6 July 2017


1. Introduction
---------------
This document briefly summarizes module by module the most important changes
made since the last release of GammaLib.

3. Configuration
-----------------
None


4. Application module
---------------------
None


5. Base module
--------------
None


6. FITS I/O Interface
---------------------
None


7. Linear algebra module
------------------------
None


8. Model module
---------------
The normalisation values of light and phase curves shall not exceed values of 1
but due to rounding problems when reading the FITS file it can happen that
slightly larger value occur. To circumvent the issue a small margin of 1e-8 has
been added to the maximum value of 1, well below the required precision for
flux normalisations (#2149).


9. Numerics module
------------------
None


10. Observation module
----------------------
None


11. Optimization module
-----------------------
None


12. Sky module
--------------
The GSkyDir class now signals that ra/dec or l/b are cached when they were
computed in the gal2equ() and equ2gal() methods, improving hence the speed
of the clients (#2148).


13. Support module
------------------
None


14. XML module
--------------
None


15. VO module
-------------
None


16. Xspec module
----------------
None


17. Test module
---------------
None


18. Multi-wavelength interface
------------------------------
None


19. Fermi-LAT interface
----------------------
None


20. CTA interface
-----------------
The GCTAPsfKing::r_max() method returned an infinite radius for a too small
gamma parameter. If the gamma parameter is too small the method now returns
a maximum radius of zero, and the GCTAPsfKing::update() method will set the
normalization to zero (#2133).


21. COMPTEL interface
---------------------
None
