AMICI v0.25.2

Fixes

• Fixed a bug in PEtab import which led to incorrect gradients
  w.r.t. estimated initial values specified via the condition table
  BREAKING CHANGE:
  amici.petab.sbml_import.{import_model_sbml,import_model} no longer supports
  passing individual PEtab tables, but only the PEtab problem object.
  This functionality was deprecated since v0.12.0 (2022-08-26).
• Fixes for numpy 2.0 compatibility
  NOTE: As long as some amici dependencies don't support numpy 2.0 yet,
  you may need to pin numpy to <2.0 in your requirements
  (pip install amici "numpy<2.0").

Full Changelog: v0.25.1...v0.25.2

AMICI v0.25.1

Fixes

• Avoid clashes with sympy-entities in plot_expressions
  by @dweindl in #2440
• PEtab: fix KeyErrors for missing parameters in fill_in_parameters
  (default values are now used if only a subset of parameters is provided)
  by @dweindl in #2449
• CMake: Fix Intel MKL detection when not using environment modules
  by @dweindl in #2443

Full Changelog: v0.25.0...v0.25.1

AMICI v0.25.0

This release requires Python >= 3.10.

Fixes

• Fixed a bug in event handling that could lead to incorrect simulation
  results for models with events that assign to compartments and have
  additional event assignments
  by @dweindl in #2428
• SBML import: handle useValuesFromTriggerTime attribute on events.
  This attribute was previously ignored. It is possible that now AMICI fails
  to import models that it previously imported successfully. For cases where
  useValuesFromTriggerTime=True made a difference, AMICI might have produced
  incorrect results before.
  by @dweindl in #2429
• Faster code generation for models with events if they don't have
  state-dependent triggers
  by @dweindl in #2417
• Most warnings now come with a more informative code location
  by @dweindl in #2421
• amici.ExpData was changed so that isinstance(edata, amici.ExpData) works
  by @dweindl in #2396

Features

• Event-assignments to compartments are now supported. Previously, this only
  worked for compartments that were rate rule targets.
  by @dweindl in #2425
• Releases are now deployed to Docker Hub
  by @dweindl in #2413

Full Changelog: v0.24.0...v0.25.0

  (positive value: check; non-positive: don't check).
