  • Fix that when the app-data seeders image creation fails the exception is silently ignored. Avoid two virtual environment creations to step on each others toes by using a lock while creating the base images. By @gaborbernat. (#1869)

v20.0.24 (2020-06-22)#

Features - 20.0.24#

  • Ensure that the seeded packages do not get too much out of date:

    • add a CLI flag that triggers upgrade of embedded wheels under upgrade-embed-wheels

    • periodically (once every 14 days) upgrade the embedded wheels in a background process, and use them if they have been released for more than 28 days (can be disabled via no-periodic-update)

    More details under Wheels - by @gaborbernat. (#1821)

  • Upgrade embed wheel content:

    • ship wheels for Python 3.9 and 3.10

    • upgrade setuptools for Python 3.5+ from 47.1.1 to 47.3.1

    by @gaborbernat. (#1841)

  • Display the installed seed package versions in the final summary output, for example:

    created virtual environment CPython3.8.3.final.0-64 in 350ms
  creator CPython3Posix(dest=/x, clear=True, global=False)
  seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=/y/virtualenv)
    added seed packages: pip==20.1.1, setuptools==47.3.1, wheel==0.34.2

  • Improve python discovery mechanism:

    • do not fail if there are executables that fail to query (e.g. for not having execute access to it) on the PATH,

    • beside the prefix folder also try with the platform dependent binary folder within that,

    by @gaborbernat. (#1545)

  • When copying (either files or trees) do not copy the permission bits, last access time, last modification time, and flags as access to these might be forbidden (for example in case of the macOs Framework Python) and these are not needed for the user to use the virtual environment - by @gaborbernat. (#1561)

  • While discovering a python executables interpreters that cannot be queried are now displayed with info level rather than warning, so now they’re no longer shown by default (these can be just executables to which we don’t have access or that are broken, don’t warn if it’s not the target Python we want) - by @gaborbernat.

  • Virtual environments created via relative path on Windows creates bad console executables - by @gaborbernat. (#1552)

v20.0.0. (2020-02-10)#

Improved Documentation - 20.0.0.#

  • Fixes typos, repeated words and inconsistent heading spacing. Rephrase parts of the development documentation and CLI documentation. Expands shorthands like env var and config to their full forms. Uses descriptions from respective documentation, for projects listed in related links - by @pradyunsg. (#1540)

v20.0.0b2 (2020-02-04)#

Features - 20.0.0b2#

  • Improve base executable discovery mechanism:

    • print at debug level why we refuse some candidates,

    • when no candidates match exactly, instead of hard failing fallback to the closest match where the priority of matching attributes is: python implementation, major version, minor version, architecture, patch version, release level and serial (this is to facilitate things to still work when the OS upgrade replace/upgrades the system python with a never version, than what the virtualenv host python was created with),

    • always resolve system_executable information during the interpreter discovery, and the discovered environment is the system interpreter instead of the venv/virtualenv (this happened before lazily the first time we accessed, and caused reporting that the created virtual environment is of type of the virtualenv host python version, instead of the system pythons version - these two can differ if the OS upgraded the system python underneath and the virtualenv host was created via copy),

    by @gaborbernat. (#1515)

  • Generate bash and fish activators on Windows too (as these can be available with git bash, cygwin or mysys2) - by @gaborbernat. (#1527)

  • Show less information when we run with a single verbosity (-v):

    • no longer shows accepted interpreters information (as the last proposed one is always the accepted one),

    • do not display the str_spec attribute for PythonSpec as these can be deduced from the other attributes,

    • for the app-data seeder do not show the type of lock, only the path to the app data directory,

    By @gaborbernat. (#1510)

  • Fixed cannot discover a python interpreter that has already been discovered under a different path (such is the case when we have multiple symlinks to the same interpreter) - by @gaborbernat. (#1512)

  • Project readme is now of type MarkDown instead of reStructuredText - by @gaborbernat. (#1531)

v20.0.0b1 (2020-01-28)#

  • First public release of the rewrite. Everything is brand new and just added.

  • --download defaults to False

  • No longer replaces builtin site module with custom version baked within virtualenv code itself. A simple shim module is used to fix up things on Python 2 only.

Warning

The current virtualenv is the second iteration of implementation. From version 0.8 all the way to 16.7.9 we numbered the first iteration. Version 20.0.0b1 is a complete rewrite of the package, and as such this release history starts from there. The old changelog is still available in the legacy branch documentation.
