--- ## 2.91.2 This release fixes hermeticity of the Pex boot code against the Python stdlib itself.

--- ## 2.90.2 This release fixes bugs resulting from imperfect isolation of Python interpreters by Pex. In particular, `sys.path` pollution from items in the `CWD` is mitigated for many common use cases.

--- ## 2.85.0 This release introduces a new `--interpreter-selection-strategy` option for use when building PEXes that use `--interpreter-constraint`s. When multiple interpreters satisfy the specified `--interpreter-constraint`s, the `--interpreter-selection-strategy` allows you to direct Pex to select the `oldest` (the default and the existing behavior) or the `newest`. In either case, the highest available patch version will be selected from amongst multiple interpeters with the same major and minor versions. * Support an `--interpreter-selection-strategy` option.
