Bugfixes

• The SSLContext caching feature originally introduced in 2.32.0 has created
  a new class of issues in Requests that have had negative impact across a number
  of use cases. The Requests team has decided to revert this feature as long term
  maintenance of it is proving to be unsustainable in its current iteration.

Deprecations

• Added support for Python 3.14.
• Dropped support for Python 3.8 following its end of support.
