2.89.0

This release exports the path of the installed .desktop file as the DESKTOP_FILE environment
variable for commands in --scie-icon and --scie-desktop-file PEX scies. The DESKTOP_FILE
path may not exist, but if it does it can be used to implement desktop application uninstallation
in the PEX scie application code.

• Export DESKTOP_FILE for PEX scie .desktop apps. (#3100)

2.88.1

This release fixes .desktop files installed by --scie-icon and --scie-desktop-file PEX scies
to be more robust. They now work even if the original PEX scie they were installed by is (re)moved
as well as properly handling a SCIE_BASE with spaces in the path.

• Fix .desktop files installed by PEX scies. (#3099)

2.86.1

This release fixes a bug in constraints file requirement parsing. Previously, Pex tried to validate
constraints beyond its own needs, anticipating Pip's needs, leading to a failure to handle direct
reference URL requirements, including VCS requirements.

• Fix constraints file parsing for URL requirements. (#3090)

2.86.0

This release adds support for Linux PEX scies installing themselves with a desktop entry on first
run. This is enabled via either of --scie-icon or --scie-desktop-file. By default, the end-user
is prompted to approve a desktop install but this can be bypassed at build time with
--no-scie-prompt-desktop-install or at runtime using the PEX_DESKTOP_INSTALL environment
variable.

• Add PEX scie Linux .desktop install support. (#3087)

This release makes running a PEX using venv-execution and sh-bootstrapping (that is, build with
--sh-boot --venv) more likely to behave identically with a cold or warm PEX_ROOT cache. This
includes running with PEX_PYTHON=..., PEX_PYTHON_PATH=..., PEX_PATH=..., PEX_VENV=... and
PEX_IGNORE_RCFILES=....

• Avoid fast-path in --sh-boot script for more variables. (#2729)
