alpaqa - 1.1.0a1

Major changes:

• Renamed problem functions (e.g. eval_f() becomes eval_objective(), get_n() becomes get_num_variables()) See https://kul-optec.github.io/alpaqa/1.1.0a1/Doxygen/page-problem-formulations.html for details.
• Renamed some solver statistics (e.g. lbfgs_failures becomes direction_failures)
• Installing the alpaqa Python package no longer requires CasADi.
  If you intend to use alpaqa with CasADi, use pip install --pre "alpaqa[casadi]"

Other changes: - New interface for defining custom inner solvers in Python - Expose Ipopt solver to Python - Use Conan package manager for installing dependencies - Simplified installation from source - CI maintenance - Added Python 3.14 support - Dropped CentOS 7 support - Dropped Python 3.8 support

alpaqa - 1.0.0a18

This release adds a casadi::external function loader that does not depend on the CasADi C++ library. This simplifies the installation and reduces the binary size.

The ALPAQA_WITH_CASADI option now enables this loader by default. To enable the full CasADi loader, which also supports other types of casadi::Function objects (e.g. symbolic expressions or serialized functions), use ALPAQA_WITH_EXTERNAL_CASADI (this requires CasADi to be installed).
