ChangeLog for selectlib
=======================
Version 4.78.1 - 2024-10-30 (AI)
------------------------------
+ SelectLexer.l and SelectParser.y renamed to prevent compilation with modern
flex and bison applications (SPR-7784)
Version 4.78 - 2023-08-09 (RDS)
------------------------------
+ (docs/selectlib_description.tex) - Improve documentation of the
region file COMPONENT column.
Version 4.77 - 2022-08-30 (AI)
------------------------------
+ (src/utils/OGIPgit.cc) mergeTimingAttributes method does not check if the attributes to
be added to the table belongs to the same table or not. If they belong to the same table,
the dal deletes the pointer to the attribute value and therefore, the new value is not correct.
Extra check added to the mergeTimingAttributes method to check if the keywords belongs
the same GTI table.
Version 4.76 - 2020-06-04 (AI)
------------------------------
+ (ServiceF90cxxGlue.h/cc) New definition of array descriptors
(Dope vector) compatible with the new Fortran standard 2018.
This modification of the Dope vector is only compatible
for gcc v8.0 and higher. Nevertheless we have kept backward
compatibility. SOC-SPR-7550
Version 4.75 - 2018-02-13 (EO)

---------------------------------------------------------------------
Version 4.74.1 - 2016-11-30 (AI)

error in MAC OSX (gcc 6.2) compilation.

now the contional expression is evaluated outside the method call.
Version 4.73 - 2015-13-03 (AI)
--------------
+ src/selcore/VectorFunctors.cc: The inner product of the median spacecraft attitude and the
current spacecraft attitude vectors can end up with a value greater than 1.0 (error propagation).
If this is the case, the ConeFilterLogic is wrong and the attitude is discared from the GTI returned by attfilter.
The result of the inner product is checked and if it is greater than one, the value is reseted to 1.0.
Version 4.72.1 - 2014-09-04 (EO)

build the release track.
