9 Small release for this end of december; This release contains only two notable changes:
10
11 - :ghpull:`14594` Fix completion in tuples, where the completion was
12 suggesting tuples methods instead of methods and attributes of the current
13 element.
14 - :ghpull:`14598` Fix pdb issue with Python 3.13.1, this fix is not perfect
15 (see :ghissue:`14620`) but should be sufficient for now.

22 Road to 9.0
23 -----------
24
25 The current main branch is now on it's way to be 9.0; do not expect many new
26 features but a large codebase refactor, and cleanup with many deprecated code
27 removed, and more agressive codestyle enforcement.

31
32 `Emmy Noether <https://en.wikipedia.org/wiki/Emmy_Noether>`__ was a German
33 mathematician who made groundbreaking contributions to abstract algebra and
34 theoretical physics. Her work on Noether's theorem, which describes the
35 relationship between symmetries and conservation laws, has had a profound impact
36 on the development of modern physics. Noether's work was largely overlooked
37 during her lifetime, but her legacy as one of the most important mathematicians
38 of the 20th century has been recognized and celebrated in recent years.
