-
-*** Changes in avr-libc-1.8.0:
-
-* Bugs fixed:
-
- [#17815] Configure does not honor --mandir option
- [#23234] Alternate interrupt macro
- [#24861] Interrupt documentation contains extra include
- [#32103] Support for Target-Triplets

-* Contributed Patches:
-
- [#7531] Bad name of bit in TCCR0A : WGM0 instead of CTC0 for ATtinyX61
- [#7362] iom16a.h: USART vectors inconsistently named for ATmega16A
- [#7226] ATMEGA8U2 Patches
-
-* Other changes:
-
- - The old prog_* typedefs are now deprecated, and are only included
- if requested by the user. This request is expressed by declaring
- the macro __PROG_TYPES_COMPAT__, either by a #define directive
- before including <avr/pgmspace.h>, or by a -D compiler option.
-
- - Optimized strlen_P, thanks to Jan Waclawek. Rename strlen_P to be
- __strlen_P and add new strlen_P inline function in header file that
- checks if value is a constant and known at compile time. If not,
- then the new inline function calls __strlen_P as normal.

-
-* Other changes:
-
- - Added 'avr35' architecture. Now 'MOVW' and 'LPM Rx, Z[+]' instructions
- supported for AT90USB82 and AT90USB162 devices. GCC 4.3 or above is
- necessary to use this.
-
- - Function vfscanf() is rewriten. The float point version is optimized
- considerably: the expense of a stack was cut by half, and the size of
- function has decreased approximately on 1KB. Opportunities of standard
- and minimal versions are expanded, and their size has remained at a
- former level.
-
- Briefly:
- . Restrictions of a float point format are eliminated.
- . Conversion '%[' is present in standart version now.
- . The minimal version differs from standard only absence of '%[' conv.
- . The 'hh' type qualifier is added ('char *', C99).
- . The maximal field width is increased up to 255 (65535 in float
version).
- . All known bugs are fixed.
-
- New vfscanf() concedes old in:
- . The size of the minimal and standard versions has increased for old
- branches of compiler (less 4.1) and ancient chips (without MOVW).
- . The maximum quantity of conversions now is limited (255).
-
- - EEPROM functions are rewriten. Now they are pure asm functions. The
- reading of long word or block is speed up. New functions for 32-bit
- words and floats are added. The group of 'update' (burn only different
- bytes) functions is added. A set of Avr-libc bugs are fixed.
-
- - Added support for XMEGA architectures.
-
- - The Postscript documentation build has been removed in favour of
- building only the PDF (and HTML and man page) versions. PDF offers
- the same printing quality as postscript at a smaller file size.
- This also works around a bug in doxygen 1.5.7 where it appears to
- be no longer possible to set GENERATE_HTML = NO.
-
- - A sleeping BOD API was added to <avr/sleep.h>. This allows you to disable
- the Brown Out Detector (BOD) before going to sleep, thereby reducing
- power even further.
-
- - The note about signbit() implementation is removed from documenatation.
- The reason is that the GCC can replace it with inline code and the
- nonzero value is unpredictable in such case.
-
- - Signature API added in <avr/signature.h>.
-
- - All functions are now placed in the .text.avr-libc section, and the
- floating point functions are placed in the .text.avr-libc.fplib section.
This
- allows the user the ability to relocate all avr-libc routines to a
different
- address using a custom linker script.
-
- - The port/pin assignments of the HD44780 LCD controller in the
- stdiodemo example can now be distributed across more than a single
- AVR port. The only remaining requirement is that all data bits
- are assigned to a single port in ascending order.
-
- - Added support for avrtiny10 architecture, to support the ATtiny10 Family.
-
- - Added new headerfile: <avr/cpufunc.h>; currently contains _NOP() and
- _MemoryBarrier().
-
- - The twidemo can now optionally address 24C32 and larger EEPROMs
- that require 16-bit word addressing.
-
- - Add a "memory barrier" to the cli() and sei() macros.

-*** Changes in avr-libc-1.6.0:
-
-* Main changes from avr-libc 1.4 to 1.6:
-
- + The fplib/math library is completely rewritten. Now features of the IEEE
- 754 standard are supported all: negative zero, subnormals, Infs and NaNs.
- It concerns both to base operations (arithmetic, comparison...), and to
- all functions. Speed of performance is increased, sometimes considerably.
- A number of mistakes (not reflected in the Bugs) which led severe losses
- of accuracy for some arguments is corrected. A number of new functions is
- added. It is necessary to note, that the new library concedes old under
- the charge of flash memory a little.
-
- Incompatibilities:
-
- - Conversion from float to long (make similar to GCC/x86): in case if
- overflow was or if input is NaN return 0x80000000 for signed result and
- return 0 for unsigned result. Negative input (not too big in absolute
- value) is permissible for cast to unsigned long, for example: (unsigned
- long)(-1.0) returns ULONG_MAX.
-
- - The signbit() function: return 1 as nonzero value (make similar to
- builtin GCC).
-
- - Make frexp() similar to GCC/x86 in case of nonfinite arg: write 0 by
- exponent pointer. Early Avr-libc's frexp() skips exponent storing in this
- case. Make the NULL a legal address to skip a storing.
-
- + Functions of numbers to ascii conversion are completely rewritten:
- dtostre(), dtostrf() and printf() family. They more do not use float point
- operations. Speed of int/float to ascii has increased in some times. For
- printf() the stack usage is reduced.
-
- + Test suite is added to the Avr-libc project.
-
- + A few new util's headers: util/atomic.h, util/setbaud.h .
-

- macros to manipulate the Power Reduction Register(s) and the System Clock
- Prescaler register across multiple processors.
-
- [patch #4611] sleep.h sleep_mode() not interrupt safe
-
- - The simple demo has been modernized a bit. Documentation now
- generally refers to the ATmega8 rather than the AT90S2313, and
- the #ifdef spaghetti has been moved out into iocompat.h.
-
- - A new demo project ("largedemo") has been added. It extends
- the simple demo by adding some controls, and thereby touches
- a good number of avr-libc concepts. It has originally been
- written for the ATmega16, but can also be run on an ATmega8
- or a member of the ATmegaX8 family, as well as on an ATtiny2313.
-
- - Another demo project ("stdiodemo") has been added. It
- demonstrates the setup of the standard IO facilities using
- a practical small application.
-
- - The demo projects now install their source code as part of
- the documentation tree.
-
- - The simple demo has been ported to ATmega8515, ATmega8535,
- ATmega164P, ATmega165, ATmega169, ATmega324P, ATmega325,
- ATmega3250, ATmega329, ATmega3290, ATmega640, ATmega644,

- cable for the largedemo as it is not part of the STK500.
-
- - Integrate a copy of the license file into the documentation.
-
- - Include an alphabetical index of all globals (functions,
- macros, types, variables) into the documentation.

- round
- lround

-* Optimized functions:
-
- dtostre
-
-*** Changes in avr-libc-1.4.0:
-
-* Major API changes:
-
- - The INTERRUPT() macro has been deprecated, and it will be
- removed in a future version. Use __attribute__((interrupt))
- explicitly if this functionality is really needed.
-
- - A new ISR() macro has been added, and is now the preferred
- for to introduce an interrupt service routine. It is
- equivalent to the old SIGNAL() macro, which might become
- deprecated in a future version.
-
- - A new header file, <compat/deprecated.h> has been established.
- Its purpose is to collect deprecated items from older versions of
- the library, starting out with the enable_external_int(),
- timer_enable_int(), and INTERRUPT() macros/functions, as well as
- the old obsoleted inp/outp/sbi/cbi macros.
-
- - A new include file subdirectory named "util/" has been created.
- The files <compat/twi.h>, <avr/crc16.h>, <avr/delay.h>, and
- <avr/parity.h> have been moved into the new util/ subdirectory.
-
- - A new set of interrupt vector names has been added, closely
- matching the names given in the datasheet, and more compatible to
- other compilers available for the AVR platform. The table of
- interrupt vector names in the documentation is now automatically
- generated, and explicitly mentions the MCU type for each vector
- name.
-
- - The standard IO facilities API has been enhanced
-
- . The backend functions put and get that are passed to fdevopen()
- during the setup of a stream now take the stream itself as an
- additional argument.
- By defining the macro __STDIO_FDEVOPEN_COMPAT_12 before
- including <stdio.h>, an fdevopen() function prototype will be
- declared that is backwards-compatible with avr-libc version
- 1.2 and before.
- . It is possible to tie user data to a stream using
- fdev_set_udata(), and to retrieve them using fdev_get_udata().
- Together with the additional argument to the backend functions,
- these functions can now e.g. keep track of internal user state,
- or distinguish two different devices using the same backend
- function.
- . The get backend function can now return _FDEV_EOF to indicate an
- end-of-file condition, in addition to _FDEV_ERR for an error
- condition. This will affect the internal state that can be
- queried using the standard feof() and ferror() functions.
- . A new macro fdev_setup_stream() is provided to setup a
- user-supplied stream without the need to call fdevopen(), and thus
- without requiring malloc(). A similar macro FDEV_SETUP_STREAM()
- exists that can be used to initialized a FILE object. The
- floating-point implementations of vfscanf() and vfprintf() now
- allocate their conversion buffer on the stack, so they do not need
- malloc() anymore either.
-
- - An API has been added to track the library version number. See the
- documentation of the new header file <avr/version.h>.

- . <avr/io.h> (cbi, sbi, inb, outb, inw, outw, inp, outp, BV),
- . <avr/pgmspace.h> (PRG_RDB).
- + . <avr/timer.h> removed completely.
-
-* Moved header files:
-
- + <avr/ina90.h> moved to <compat/ina90.h>
- + <avr/twi.h> moved to <compat/twi.h>
-
-* New devices supported:
-
- + ATmega165
- + ATmega325
- + ATmega3250
- + ATmega645
- + ATmega6450
- + ATmega48
- + ATmega88
- + ATmega168
- + ATtiny13
- + ATtiny2313
- + AT90CAN128
-
-* Pin names for ports are now consistent for all devices.
-
-* dtostrf() now uses movw where possible
-
-* realloc() has been implemented.
-
-* Extend pgmspace API.
-
-The pgmspace API has had the following macros added to allow accessing of
-unsigned 32-bit values:
-
- pgm_read_dword_near
- pgm_read_dword_far
- pgm_read_dword
-
-* Change boot API.
-
-The boot API internals have changed such that it is not compatible with the
-1.0.x API.
-
-These macros have been changed so that they no longer wait for SPM and EEPROM
-operations to complete. It turns out that doing those checks all the time is
-not needed and tends to bloat the code. Removing the checks allows you to
-write more compact code (see the example in avr/boot.h).
-
- boot_page_fill
- boot_page_erase
- boot_page_write
- boot_rww_enable
- boot_lock_bits_set
-
-If you want the old behaviour (1.0.x compatible), use these new macros:
-
- boot_page_fill_safe
- boot_page_erase_safe
- boot_page_write_safe
- boot_rww_enable_safe
- boot_lock_bits_set_safe
-
-* Extend eeprom API.
-
-New macro:
- eeprom_busy_wait
-
-* Extend crc16 API.
-
-New functions:
- _crc_xmodem_update
- _crc_ccitt_update
-
-* Extend stdio API.
-
-New functions:
- vfprintf_P
- vfscanf_P
- vsprintf
- vsprintf_P
- vsnprintf
- vsnprintf_P
-
-* Extend malloc API.
-
-Implement realloc().
-
-* Extend delay API (<avr/delay.h>).
-
-Implement inline functions for specifying delays in microseconds, or
-milliseconds directly (based on the macro F_CPU specifying the CPU
-clock frequency).
-
-* Documentation changes:
-
- + Use newer Doxygen.
- + Many fixes and added documentation.
- + Unix-style man pages are generated now when doc generation has been
- enabled in ./configure
-
-* Optimize slightly strtol and strtoul functions.
-
-* Unified copyright.
-
-All of the avr-libc files are now distributed under a single license.
-All of the authors of the files agreed to this step. The new license
-is a 3-clause simplified ``BSD-style'' license which is believed to be
-fully compatible with the GPL on one hand, yet imposes as minimal
-restrictions as possible for any kind of commercial use in
-applications based on avr-libc.
-
-To build the documentation, doxygen-1.3.4 or newer is strongly recommended.
-
-*** Changes in avr-libc-1.0:
-
-* Move source to cvs repositiory at http://savannah.gnu.org/projects/avr-libc
-
-Anonymous cvs access to the source is now available. There is also a mailing
-list set up for discussion of development of avr-libc.
-
-* License changes.
-
-All the files in the project now are covered by a modified BSD license. This
-allows royalty free use of the library in commerical products. All of the
-public domain files in the project have been switched to the new license and
-copyright given to the contributors of the files.
-
-There were some files taken from GNU GPL'd projects which were removed from
-avr-libc to simplify the licensing. The removed files only supplied alternate
-implementations, so nothing was lost by their removal.
-
-* Requires latest binutils and gcc
-
-Marek did some fairly major work with binutils and gcc to make adding support
-for new devices easier. His changes in those tools required changes to
-avr-libc which make it incompatible with older versions of binutils and gcc.
-Gcc versions >= 3.3 and binutils versions >= 2.13 are required.
-
-* New malloc implementation.
-
-Joerg Wunsch has supplied an improved malloc implementation which is less
-prone to fragmentation.
-
-* Documentation!
-
-Joerg Wunsch and Ted Roth and have been working on using the doxygen program to
-embed documentation comments into source code. Additionally, Harald Kipp's
-inline asm cookbook and Rich Neswold's Avr Tools document have been merged into
-the user manual. The goal is to have a single place for all the documentation
-a user would need to get started developing for AVR microcontrollers using
-the GNU development tool chain.
-
-The latest documentation is available online at
- http://www.freesoftware.fsf.org/avr-libc/
-
-* I/O registers accessible directly in C expressions
-
-You can now do this in your code:
- PORTA |= 0x02;
-
-See the "Special Function Registers" documentation for details. This method is
-preferred over the use of the deprecated inp(), inb(), inw(), outp(), outb()
-and outw() functions.
-
-* New devices supported
-
-mega128
-mega169
-mega16
-mega32
-mega64 [untested]
-mega8515 [untested]
-mega8535 [untested]
-tiny26
-76c711
-43usb320
-43usb355
-86rf401
-
-* Improved trigonometrical functions:
-
-Reiner Patommel provided complete rewrites for asin(), atan() and atan2()
-that feature a better (for some argument ranges even much better)
-accuracy than the previous versions. Note that since acos() uses asin(),
-it also benefits from this.
-
-* Incompatibilities with previous version.
-
-The arguments for outb()/outw() have been reversed.
- (value,port) -> (port,value)
-
-* New pgmspace.h API.
-
-Changed function names and added new functions to read the Program Space
-FLASH. Added new functions to read 16-bit (word) values. The new API should
-also clear up problems with reading data from devices with > 64K of FLASH.
-
-The API now includes:
-pgm_read_byte (maps to the *_near function below)
-pgm_read_word (maps to the *_near function below)
-pgm_read_byte_near
-pgm_read_word_near
-pgm_read_byte_far
-pgm_read_word_far
-
-
-* New bootloader support API.
-
-#include <avr/boot.h>
-
-This provides bootloader support functions to those processors that have
-builtin bootloader support.
-
-* inb / outb / inw / outw / cbi / sbi macros are deprecated.
-
-* New string functions and optimized string functions.
-
-strlcpy (optimized)
-strlcat (optimized)
-strsep (new)
-strtok_r (new)
-strlcat_P (new)
-strlcpy_P (new)
-strncat_P (new)
-
-Contributed by Reiner Patommel with some work on strlcpy, strlcat by
-Eric Weddington.
-
-* New eeprom functions by Artur Lipowski <LAL@pro.onet.pl>
-
-eeprom_write_word
-eeprom_write_block
-
-

+
+*** Changes in avr-libc-1.8.0:

+ [#7362] iom16a.h: USART vectors inconsistently named for ATmega16A
+ [#7226] ATMEGA8U2 Patches
+
+* Other changes:
+
+ - The old prog_* typedefs are now deprecated, and are only included
+ if requested by the user. This request is expressed by declaring
+ the macro __PROG_TYPES_COMPAT__, either by a #define directive
+ before including <avr/pgmspace.h>, or by a -D compiler option.
+
+ - Optimized strlen_P, thanks to Jan Waclawek. Rename strlen_P to be
+ __strlen_P and add new strlen_P inline function in header file that
+ checks if value is a constant and known at compile time. If not,
+ then the new inline function calls __strlen_P as normal.

+ - Function vfscanf() is rewriten. The float point version is optimized
+ considerably: the expense of a stack was cut by half, and the size of
+ function has decreased approximately on 1KB. Opportunities of standard
+ and minimal versions are expanded, and their size has remained at a
+ former level.
+
+ Briefly:
+ . Restrictions of a float point format are eliminated.
+ . Conversion '%[' is present in standart version now.
+ . The minimal version differs from standard only absence of '%[' conv.
+ . The 'hh' type qualifier is added ('char *', C99).
+ . The maximal field width is increased up to 255 (65535 in float
version).
+ . All known bugs are fixed.
+
+ New vfscanf() concedes old in:
+ . The size of the minimal and standard versions has increased for old
+ branches of compiler (less 4.1) and ancient chips (without MOVW).
+ . The maximum quantity of conversions now is limited (255).
+
+ - EEPROM functions are rewriten. Now they are pure asm functions. The
+ reading of long word or block is speed up. New functions for 32-bit
+ words and floats are added. The group of 'update' (burn only different
+ bytes) functions is added. A set of Avr-libc bugs are fixed.
+
+ - Added support for XMEGA architectures.
+
+ - The Postscript documentation build has been removed in favour of
+ building only the PDF (and HTML and man page) versions. PDF offers
+ the same printing quality as postscript at a smaller file size.
+ This also works around a bug in doxygen 1.5.7 where it appears to
+ be no longer possible to set GENERATE_HTML = NO.
+
+ - A sleeping BOD API was added to <avr/sleep.h>. This allows you to disable
+ the Brown Out Detector (BOD) before going to sleep, thereby reducing
+ power even further.
+
+ - The note about signbit() implementation is removed from documenatation.
+ The reason is that the GCC can replace it with inline code and the
+ nonzero value is unpredictable in such case.
+
+ - Signature API added in <avr/signature.h>.
+
+ - All functions are now placed in the .text.avr-libc section, and the
+ floating point functions are placed in the .text.avr-libc.fplib section.
This
+ allows the user the ability to relocate all avr-libc routines to a
different
+ address using a custom linker script.
+
+ - The port/pin assignments of the HD44780 LCD controller in the
+ stdiodemo example can now be distributed across more than a single
+ AVR port. The only remaining requirement is that all data bits
+ are assigned to a single port in ascending order.
+
+ - Added support for avrtiny10 architecture, to support the ATtiny10 Family.
+
+ - Added new headerfile: <avr/cpufunc.h>; currently contains _NOP() and
+ _MemoryBarrier().
+
+ - The twidemo can now optionally address 24C32 and larger EEPROMs
+ that require 16-bit word addressing.
+
+ - Add a "memory barrier" to the cli() and sei() macros.

+*** Changes in avr-libc-1.6.0:
+
+* Main changes from avr-libc 1.4 to 1.6:
+
+ + The fplib/math library is completely rewritten. Now features of the IEEE
+ 754 standard are supported all: negative zero, subnormals, Infs and NaNs.
+ It concerns both to base operations (arithmetic, comparison...), and to
+ all functions. Speed of performance is increased, sometimes considerably.
+ A number of mistakes (not reflected in the Bugs) which led severe losses
+ of accuracy for some arguments is corrected. A number of new functions is
+ added. It is necessary to note, that the new library concedes old under
+ the charge of flash memory a little.
+
+ Incompatibilities:
+
+ - Conversion from float to long (make similar to GCC/x86): in case if
+ overflow was or if input is NaN return 0x80000000 for signed result and
+ return 0 for unsigned result. Negative input (not too big in absolute
+ value) is permissible for cast to unsigned long, for example: (unsigned
+ long)(-1.0) returns ULONG_MAX.
+
+ - The signbit() function: return 1 as nonzero value (make similar to
+ builtin GCC).
+
+ - Make frexp() similar to GCC/x86 in case of nonfinite arg: write 0 by
+ exponent pointer. Early Avr-libc's frexp() skips exponent storing in this
+ case. Make the NULL a legal address to skip a storing.
+
+ + Functions of numbers to ascii conversion are completely rewritten:
+ dtostre(), dtostrf() and printf() family. They more do not use float point
+ operations. Speed of int/float to ascii has increased in some times. For
+ printf() the stack usage is reduced.
+
+ + Test suite is added to the Avr-libc project.
+
+ + A few new util's headers: util/atomic.h, util/setbaud.h .
+
+* Bugs fixed:
+
+ [no-id] iscntrl() return true for some values from 0x80 to 0xff.

+
+* Other changes:
+
+ - New Power Management API in <avr/power.h>. This provides C language
+ macros to manipulate the Power Reduction Register(s) and the System Clock
+ Prescaler register across multiple processors.
+
+ [patch #4611] sleep.h sleep_mode() not interrupt safe
+
+ - The simple demo has been modernized a bit. Documentation now
+ generally refers to the ATmega8 rather than the AT90S2313, and
+ the #ifdef spaghetti has been moved out into iocompat.h.
+
+ - A new demo project ("largedemo") has been added. It extends
+ the simple demo by adding some controls, and thereby touches
+ a good number of avr-libc concepts. It has originally been
+ written for the ATmega16, but can also be run on an ATmega8
+ or a member of the ATmegaX8 family, as well as on an ATtiny2313.
+
+ - Another demo project ("stdiodemo") has been added. It
+ demonstrates the setup of the standard IO facilities using
+ a practical small application.
+
+ - The demo projects now install their source code as part of
+ the documentation tree.
+
+ - The simple demo has been ported to ATmega8515, ATmega8535,
+ ATmega164P, ATmega165, ATmega169, ATmega324P, ATmega325,
+ ATmega3250, ATmega329, ATmega3290, ATmega640, ATmega644,
+ ATmega644P, ATmega645, ATmega6450, ATmega649, ATmega6490,
+ ATmega1280, ATmega1281, ATtiny2313, ATtiny24, ATtiny25, ATtiny26,
+ ATtiny261, ATtiny44, ATtiny45, ATtiny461, ATtiny84, ATtiny85,
+ ATtiny861.
+
+ - More overhaul of the demo documentation, don't use the "squid"
+ cable for the largedemo as it is not part of the STK500.
+
+ - Integrate a copy of the license file into the documentation.
+
+ - Include an alphabetical index of all globals (functions,
+ macros, types, variables) into the documentation.
+
+ - Added 'avr25' architecture. Now 'MOVW' and 'LPM Rx, Z[+]' instructions
+ supported for AT86RF401, ATtiny13, ATtiny2313, ATtiny24, ATtiny25,
+ ATtiny261, ATtiny44, ATtiny45, ATtiny461, ATtiny84, ATtiny85 and
+ ATtiny861 devices. GCC 4.2 or above is necessary to use this.
+
+ - Add the benchmark page.
+
+ [patch #5756] New atomic.h header file (added as <util/atomic.h>)
+

+
+*** Changes in avr-libc-1.4.0:
+
+* Major API changes:
+
+ - The INTERRUPT() macro has been deprecated, and it will be
+ removed in a future version. Use __attribute__((interrupt))
+ explicitly if this functionality is really needed.
+
+ - A new ISR() macro has been added, and is now the preferred
+ for to introduce an interrupt service routine. It is
+ equivalent to the old SIGNAL() macro, which might become
+ deprecated in a future version.
+
+ - A new header file, <compat/deprecated.h> has been established.
+ Its purpose is to collect deprecated items from older versions of
+ the library, starting out with the enable_external_int(),
+ timer_enable_int(), and INTERRUPT() macros/functions, as well as
+ the old obsoleted inp/outp/sbi/cbi macros.
+
+ - A new include file subdirectory named "util/" has been created.
+ The files <compat/twi.h>, <avr/crc16.h>, <avr/delay.h>, and
+ <avr/parity.h> have been moved into the new util/ subdirectory.
+
+ - A new set of interrupt vector names has been added, closely
+ matching the names given in the datasheet, and more compatible to
+ other compilers available for the AVR platform. The table of
+ interrupt vector names in the documentation is now automatically
+ generated, and explicitly mentions the MCU type for each vector
+ name.
+
+ - The standard IO facilities API has been enhanced
+
+ . The backend functions put and get that are passed to fdevopen()
+ during the setup of a stream now take the stream itself as an
+ additional argument.
+ By defining the macro __STDIO_FDEVOPEN_COMPAT_12 before
+ including <stdio.h>, an fdevopen() function prototype will be
+ declared that is backwards-compatible with avr-libc version
+ 1.2 and before.
+ . It is possible to tie user data to a stream using
+ fdev_set_udata(), and to retrieve them using fdev_get_udata().
+ Together with the additional argument to the backend functions,
+ these functions can now e.g. keep track of internal user state,
+ or distinguish two different devices using the same backend
+ function.
+ . The get backend function can now return _FDEV_EOF to indicate an
+ end-of-file condition, in addition to _FDEV_ERR for an error
+ condition. This will affect the internal state that can be
+ queried using the standard feof() and ferror() functions.
+ . A new macro fdev_setup_stream() is provided to setup a
+ user-supplied stream without the need to call fdevopen(), and thus
+ without requiring malloc(). A similar macro FDEV_SETUP_STREAM()
+ exists that can be used to initialized a FILE object. The
+ floating-point implementations of vfscanf() and vfprintf() now
+ allocate their conversion buffer on the stack, so they do not need
+ malloc() anymore either.
+
+ - An API has been added to track the library version number. See the
+ documentation of the new header file <avr/version.h>.

+ + obsolete headers from the base include directory (moved to the avr/
+ subdirectory long ago)
+ + deprecated macros and functions from
+ . <avr/eeprom.h> (eeprom_rb, eeprom_rw, eeprom_wb),
+ . <avr/io.h> (cbi, sbi, inb, outb, inw, outw, inp, outp, BV),
+ . <avr/pgmspace.h> (PRG_RDB).
+ + . <avr/timer.h> removed completely.
+
+* Moved header files:
+
+ + <avr/ina90.h> moved to <compat/ina90.h>
+ + <avr/twi.h> moved to <compat/twi.h>
+
+* New devices supported:
+
+ + ATmega165
+ + ATmega325
+ + ATmega3250
+ + ATmega645
+ + ATmega6450
+ + ATmega48
+ + ATmega88
+ + ATmega168
+ + ATtiny13
+ + ATtiny2313
+ + AT90CAN128
+
+* Pin names for ports are now consistent for all devices.
+
+* dtostrf() now uses movw where possible
+
+* realloc() has been implemented.
+
+* Extend pgmspace API.
+
+The pgmspace API has had the following macros added to allow accessing of
+unsigned 32-bit values:
+
+ pgm_read_dword_near
+ pgm_read_dword_far
+ pgm_read_dword
+
+* Change boot API.
+
+The boot API internals have changed such that it is not compatible with the
+1.0.x API.
+
+These macros have been changed so that they no longer wait for SPM and EEPROM
+operations to complete. It turns out that doing those checks all the time is
+not needed and tends to bloat the code. Removing the checks allows you to
+write more compact code (see the example in avr/boot.h).
+
+ boot_page_fill
+ boot_page_erase
+ boot_page_write
+ boot_rww_enable
+ boot_lock_bits_set
+
+If you want the old behaviour (1.0.x compatible), use these new macros:
+
+ boot_page_fill_safe
+ boot_page_erase_safe
+ boot_page_write_safe
+ boot_rww_enable_safe
+ boot_lock_bits_set_safe
+
+* Extend eeprom API.
+
+New macro:
+ eeprom_busy_wait
+
+* Extend crc16 API.
+
+New functions:
+ _crc_xmodem_update
+ _crc_ccitt_update
+
+* Extend stdio API.
+
+New functions:
+ vfprintf_P
+ vfscanf_P
+ vsprintf
+ vsprintf_P
+ vsnprintf
+ vsnprintf_P
+
+* Extend malloc API.
+
+Implement realloc().
+
+* Extend delay API (<avr/delay.h>).
+
+Implement inline functions for specifying delays in microseconds, or
+milliseconds directly (based on the macro F_CPU specifying the CPU
+clock frequency).
+
+* Documentation changes:
+
+ + Use newer Doxygen.
+ + Many fixes and added documentation.
+ + Unix-style man pages are generated now when doc generation has been
+ enabled in ./configure
+
+* Optimize slightly strtol and strtoul functions.
+
+* Unified copyright.
+
+All of the avr-libc files are now distributed under a single license.
+All of the authors of the files agreed to this step. The new license
+is a 3-clause simplified ``BSD-style'' license which is believed to be
+fully compatible with the GPL on one hand, yet imposes as minimal
+restrictions as possible for any kind of commercial use in
+applications based on avr-libc.
+
+To build the documentation, doxygen-1.3.4 or newer is strongly recommended.
+
+*** Changes in avr-libc-1.0:
+
+* Move source to cvs repositiory at http://savannah.gnu.org/projects/avr-libc
+
+Anonymous cvs access to the source is now available. There is also a mailing
+list set up for discussion of development of avr-libc.
+
+* License changes.
+
+All the files in the project now are covered by a modified BSD license. This
+allows royalty free use of the library in commerical products. All of the
+public domain files in the project have been switched to the new license and
+copyright given to the contributors of the files.
+
+There were some files taken from GNU GPL'd projects which were removed from
+avr-libc to simplify the licensing. The removed files only supplied alternate
+implementations, so nothing was lost by their removal.
+
+* Requires latest binutils and gcc
+
+Marek did some fairly major work with binutils and gcc to make adding support
+for new devices easier. His changes in those tools required changes to
+avr-libc which make it incompatible with older versions of binutils and gcc.
+Gcc versions >= 3.3 and binutils versions >= 2.13 are required.
+
+* New malloc implementation.
+
+Joerg Wunsch has supplied an improved malloc implementation which is less
+prone to fragmentation.
+
+* Documentation!
+
+Joerg Wunsch and Ted Roth and have been working on using the doxygen program to
+embed documentation comments into source code. Additionally, Harald Kipp's
+inline asm cookbook and Rich Neswold's Avr Tools document have been merged into
+the user manual. The goal is to have a single place for all the documentation
+a user would need to get started developing for AVR microcontrollers using
+the GNU development tool chain.
+
+The latest documentation is available online at
+ http://www.freesoftware.fsf.org/avr-libc/
+
+* I/O registers accessible directly in C expressions
+
+You can now do this in your code:
+ PORTA |= 0x02;
+
+See the "Special Function Registers" documentation for details. This method is
+preferred over the use of the deprecated inp(), inb(), inw(), outp(), outb()
+and outw() functions.
+
+* New devices supported
+
+mega128
+mega169
+mega16
+mega32
+mega64 [untested]
+mega8515 [untested]
+mega8535 [untested]
+tiny26
+76c711
+43usb320
+43usb355
+86rf401
+
+* Improved trigonometrical functions:
+
+Reiner Patommel provided complete rewrites for asin(), atan() and atan2()
+that feature a better (for some argument ranges even much better)
+accuracy than the previous versions. Note that since acos() uses asin(),
+it also benefits from this.
+
+* Incompatibilities with previous version.
+
+The arguments for outb()/outw() have been reversed.
+ (value,port) -> (port,value)
+
+* New pgmspace.h API.
+
+Changed function names and added new functions to read the Program Space
+FLASH. Added new functions to read 16-bit (word) values. The new API should
+also clear up problems with reading data from devices with > 64K of FLASH.
+
+The API now includes:
+pgm_read_byte (maps to the *_near function below)
+pgm_read_word (maps to the *_near function below)
+pgm_read_byte_near
+pgm_read_word_near
+pgm_read_byte_far
+pgm_read_word_far
+
+
+* New bootloader support API.
+
+#include <avr/boot.h>
+
+This provides bootloader support functions to those processors that have
+builtin bootloader support.
+
+* inb / outb / inw / outw / cbi / sbi macros are deprecated.
+
+* New string functions and optimized string functions.
+
+strlcpy (optimized)
+strlcat (optimized)
+strsep (new)
+strtok_r (new)
+strlcat_P (new)
+strlcpy_P (new)
+strncat_P (new)
+
+Contributed by Reiner Patommel with some work on strlcpy, strlcat by
+Eric Weddington.
+
+* New eeprom functions by Artur Lipowski <LAL@pro.onet.pl>
+
+eeprom_write_word
+eeprom_write_block
+
+
+*** Changes up to avr-libc-20020203:
