GNU gama 1.13 has been released.  It is available from and mirrors of that site (see list of

GNU Gama is a project dedicated to adjustment of geodetic networks.
Network adjustment in a local coordinate system and its functionality
is represented by the program `gama-local', which adjusts geodetic
(free) networks of observed distances, directions, angles, height
differences, 3D vectors and observed coordinates (coordinates with
given variance-covariance matrix).  Global coordinate network
adjustment model is based on geocentric coordinate system (adjustment
model on ellipsoid). Its functionality is represented by the program

Version 1.13

   * Fixed templates lookup name syntax errors reported by Brandon
     Invergo <address@hidden> (detected by compiler g++-4.7).
     Many thanks for your patch, Brandon.

   * Fixed a bug reported by Jacques Beilin <address@hidden>

     Function NormalDistribution ended in an endless loop for high
     values of input argument x.

   * Fixed a bug reported by Anton Horpynich <address@hidden>

     The computation of approximate coordinates failed if an angle
     needed for computing of an intersection was smaller than 0.15
     radians / 10 gons (implicit testing criterion). Although this is a
     reasonable limit for standard surveying networks, in a batch
     computation of approximate coordinates a much smaller value can be
     sometimes acceptable. It is more or less a matter of personal
     opinion if this is to be supposed a bug or not.

     Gama newly solves approximate coordinates in two main loops.
     During the first loop the default value 0.15 in class Acord is
     used.  If afterwards there  still some coordinates remain
     missing, Gama starts a second loop with series of iterations in
     which firstly tries to find a solution with the default value
     then secondly with a very tiny limit of 0.0015 radians.

     In most cases all coordinates are solved in the first loop with
     the default small angle limit 10 gons.

   * In gama-local suppressed output of running results during
     linearization iterations and several other minor fixes
