giac-1.9.0.27-bp155.2.8

- Update to version 1.9.0.23:
  + English documentation new layout/fixes.
  + improvements mainly in nlpsolve (implements now a fast and
    robust interior-point algorithm, alongside Nelder-Mead and
    differential evolution methods for derivative-free
    optimization) and global minimization of a continuous function
    on a segment (find_minimum).
  + Integration of the 3d renderer for calculators, gives now a
    simpler alternative to OpenGL (useful if OpenGL inside Xcas
    raises bugs like black screen).
  + compatibility with new Numworks calculator bootloader.

- Update to version 1.7.0.43
  * changing interpreter in Xcas web is now much easier, improved Numworks connectivity
  * improvements and fixes by Luka Marohnić in graph theory commands, better graphs inside texmacs
  * Numworks connectivity
  * override build date from SOURCE_DATE_EPOCH (boo#1047218)

- Update to version 1.7.0.13:
  * polynomial system solver optimizations (rational univariate
    representation computation and real root isolation).
- Changes from version 1.7.0:
  * Javascript interpreter added: QuickJS.
- Changes from version 1.6.17:
  * Compatibility with calculators (KhiCAS sessions for Numworks,
    TI nspire CX).
  * Inclusion of a MicroPython interpreter (with builtin modules
    for teaching), you can switch interpreter by typing python or
    xcas in an empty commandline.
- Changes from version 1.6.0:
  * Improved FFT over finite field, half-GCD implementation.
- Enforce '-std=c++14' for openSUSE >= 1550 to build with gcc 11,
  as giac codebase isn't C++17 ready.
- Fix a few more script-without-shebang issues.
- Drop install_info post scriptlets and associated BuildRequires;
  these have been managed by file triggers for a while now.

- Modernize RPM constructs. Remove %post(un) logic that expands
  to empty strings.
- Remove pkgconfig(ao) from giac-devel, the headers do not use it.

- Replace undefined %info_add/%info_del.

- Update to version 1.5.0.85

- Remove devel-static subpackage. There is no reason to ship these.
- Remove .la files. These do not constitute static libs, either.
- Use find -delete rather than expensively calling -exec rm.

- Fix building on Leap 42.3

- Update to version 1.5.0.21
- Split xcas gui into own subpackage

- Update to 1.4.9:
  * Python compatibility mode
  * User manual corrected
- Change in 1.2.3:
  * Some speedups and bug fixes

- Fix postun scriptlet failed:
  * use install_info_delete instead of info_del

- Update to 1.2.2:
  * improved Groebner basis engine

- Initial release
