Release 1.5.0 -- 2025/05/03

Memory:

- Enforce ``age_limit`` is a positive timedelta for ``Memory.reduce_size``,
  to avoid silently ignoring it.
  https://github.com/joblib/joblib/pull/1613


Remove deprecated bytes_limit argument for Memory, which should

be passed directly to Memory.reduce_size.

joblib/joblib#1569


Extend functionality of the check_call_in_cache method to now also

check against cache validity. Before, it would only check for a given call

if it is in cache memory.

joblib/joblib#1584


The Memory object now automatically creates a .gitignore file in its

cache directory, instructing git to ignore the entire folder.

joblib/joblib#1674


Parallel:

• Fixed a bug that caused the timeout parameter in joblib.Parallel to be ineffective when used along with return_as='generator_unordered'. joblib/joblib#1586

• Pretty printing of Parallel execution progress when the number of tasks is known. joblib/joblib#1608

• Make it possible to pass extra arguments to the LokyBackend and MultiprocessingBackend, enabling the use of initializer. joblib/joblib#1525

• Refactor and document the custom parallel backend API. joblib/joblib#1667
