### Added
- [#1716](https://github.com/pints-team/pints/pull/1716) PINTS is now tested on Python 3.14.
- [#1715](https://github.com/pints-team/pints/pull/1715) Added methods `ProblemErrorMeasure.problem()`, `ProblemLogLikelihood.problem()`, `SingleOutputProblem.model()` and `MultiOutputProblem.model()`.
- [#1508](https://github.com/pints-team/pints/pull/1508) Added a method `OptimisationController.set_parameter_tolerance` that allows methods to stop after a fixed number of iterations with no significant movement in parameter space.
### Changed
- [#1713](https://github.com/pints-team/pints/pull/1713) PINTS now requires matplotlib 2.2 or newer.
### Deprecated
- [#1508](https://github.com/pints-team/pints/pull/1508) The methods `OptimisationController.max_unchanged_iterations` and `set_max_unchanged_iterations` are deprecated, in favour of `function_tolerance` and `set_function_tolerance` respectively.
### Removed
### Fixed
- [#1713](https://github.com/pints-team/pints/pull/1713) Fixed Numpy 2.4.1 compatibility issues.
