Release notes

• Version 4.0.0

  Use cmake to compile the library. Binary ABI may be broken by this major change in the compilation process. The library remains compatible at the source level: the existing application therefore only needs a recompilation.

  Add the function calceph_getidbyname and calceph_getnamebyidss.

  Fix potential crash of fortran-90 interface only, on 32-bit OS, if ephemeris file does not exist.

  Support frame name with any character except tab, space, comma, parenthese, equal, in the frame SPICE kernel file (files .tf).

  Fix system error messages to be thread-safe (remove strerror).

  Fix memory buffer overflow if the number of constants is greater than 400 in the original JPL files.

• Version 3.5.5

  Fix memory leaks when files are closed.

  Fix heap buffer overflow (read only operation) with text SPICE kernel files.

  Fix memory crash if the SPICE kernel files contain segments with a size of the directory greater than 100.

• Version 3.5.4

  Fix the documentation about the unsupported segment 19.

  Fix the window size if requested time is near a boundary for SPICE kernel files containing segments of type 18, compliant with the SPICE specifications.

  Fix random crash or double-free error when meta-kernel SPICE kernel files are closed (files .mk).

  Raise an error inside the function calceph_compute if center != 0 for the target (14,15,16,17), to conform to the documentation.

  Add the function calceph_getmaxsupportedorder, calceph_getpositionrecordindex2 and calceph_getorientrecordindex2.

  Update config.sub and config.guess to support new processors.

  Fix an incorrect result of calceph_(s)getconstant and calceph_getconstantvd with SPICE text kernel

  if the current locale has a decimal separator different than the decimal point (e.g. comma).

  Fix compilation warnings with gcc 11 about pointers and arrays.

  Fix the installation with python 3.10 or later (PEP 632).

  Fix compilation errors with the android SDK API level < 24.

  Reduce the stack size of the arrays for the evaluation with C99 compilers.

  Change the array size of the function calceph_getfileversion from the value CALCEPH_MAX_CONSTANTNAME

  to CALCEPH_MAX_CONSTANTVALUE, to conform to the documentation and examples.

  Only C and Fortran 2003 are affected by this change : previous header file contains an invalid declaration of the function.

  Few programs may be affected by this change, as the required array has a smaller size : No buffer overflow may appear.

• Version 3.4.7

  Fix a decode error of the little-endian SPICE kernel files on the big-endian architectures (e.g. processor s390x).

  Fix the transmission of the flags FCFLAGS to the fortran compilers.

• Version 3.4.5

  Fix a random crash of calceph_open_array if one of the file is invalid.

  f90calceph_seterrorhandler now ignores the parameter userfunc, instead of the requirement to set to 0, if the parameter type is 1 or 2. userfunc can be an empty function. It fixes compilation errors with gcc 10.1.
