-Note: During the 1.9 series, we will keep an incremental NEWS for the
-latest prerelease, and a full NEWS corresponding to 1.8 -> 2.0.
-Changes since the 1.9.15 prerelease:
-** `unquote' and `unquote-splicing' accept multiple expressions
-As per the R6RS, these syntax operators can now accept any number of
-expressions to unquote.
-** `getopt-long' parsing errors throw to `quit', not `misc-error'
-This change should inhibit backtraces on argument parsing errors.
-`getopt-long' has been modified to print out the error that it throws
-** New helpers: `print-exception', `set-exception-printer!'
-These functions implement an extensible exception printer. Guile
-registers printers for all of the exceptions it throws. Users may add
-their own printers. There is also `scm_print_exception', for use by C
-programs. Pleasantly, this allows SRFI-35 and R6RS exceptions to be
-** `positions' reader option enabled by default
-This change allows primitive-load without --auto-compile to also
-propagate source information through the expander, for better errors and
-to let macros know their source locations. The compiler was already
-turning it on anyway.
-** `load' is a macro (!) that resolves paths relative to source file dir
-The familiar Schem `load' procedure is now a macro that captures the
-name of the source file being expanded, and dispatches to the new
-`load-in-vicinity'. Referencing `load' by bare name returns a closure
-that embeds the current source file name.
-This fix allows `load' of relative paths to be resolved with respect to
-the location of the file that calls `load'.
-** "autocompile" -> "auto-compile"
-The "--autocompile" and "--no-autocompile" arguments were renamed to
-have a dash, for consistency with the GUILE_AUTO_COMPILE environment
-variable, and with common conventions. A number of variables were also
-** `scm_primitive_load' defaults to UTF-8, not Latin-1
-Like `compile-file', `primitive-load' now defaults to UTF-8.
-** Warning now available for auto-compiled files.
-See the `%auto-compilation-options' variable. Warnings at
-auto-compilation time are preceded with the `*current-warning-prefix*'
-** Deprecated: primitive properties
-The `primitive-make-property', `primitive-property-set!',
-`primitive-property-ref', and `primitive-property-del!' procedures were
-crufty and only used to implement object properties, which has a new,
-threadsafe implementation. Use object properties or weak hash tables
-** New syntax: define-once
-`define-once' is like Lisp's `defvar': it creates a toplevel binding,
-but only if one does not exist already.
-** Added four new sets of fast quotient and remainder operators
-Added four new sets of fast quotient and remainder operators with
-different semantics than the R5RS operators. They support not only
-integers, but all reals, including exact rationals and inexact
-floating point numbers.
-These procedures accept two real numbers N and D, where the divisor D
-must be non-zero. Each set of operators computes an integer quotient
-Q and a real remainder R such that N = Q*D + R and |R| < |D|. They
-differ only in how N/D is rounded to produce Q.
-`floor-quotient' and `floor-remainder' compute Q and R, respectively,
-where Q has been rounded toward negative infinity. `floor/' returns
-both Q and R, and is more efficient than computing each separately.
-Note that when applied to integers, `floor-remainder' is equivalent to
-the R5RS integer-only `modulo' operator. `ceiling-quotient',
-`ceiling-remainder', and `ceiling/' are similar except that Q is
-rounded toward positive infinity.
-For `truncate-quotient', `truncate-remainder', and `truncate/', Q is
-rounded toward zero. Note that when applied to integers,
-`truncate-quotient' and `truncate-remainder' are equivalent to the
-R5RS integer-only operators `quotient' and `remainder'.
-For `round-quotient', `round-remainder', and `round/', Q is rounded to
-the nearest integer, with ties going to the nearest even integer.
-** Improved exactness handling for complex number parsing
-When parsing non-real complex numbers, exactness specifiers are now
-applied to each component, as is done in PLT Scheme. For complex
-numbers written in rectangular form, exactness specifiers are applied
-to the real and imaginary parts before calling scm_make_rectangular.
-For complex numbers written in polar form, exactness specifiers are
-applied to the magnitude and angle before calling scm_make_polar.
-Previously, exactness specifiers were applied to the number as a whole
-_after_ calling scm_make_rectangular or scm_make_polar.
-For example, (string->number "#i5.0+0i") now does the equivalent of:
- (make-rectangular (exact->inexact 5.0) (exact->inexact 0))
-which yields 5.0+0.0i. Previously it did the equivalent of:
- (exact->inexact (make-rectangular 5.0 0))
-which yielded 5.0.
-Changes in 1.9.x (since the 1.8.x series):
