pipenv 2026.6.2 (2026-06-02)

Features & Improvements

• Added support for cool-down-period in the [pipenv] section of the Pipfile. Setting cool-down-period = "30d" instructs the resolver to only consider package versions uploaded at least the specified number of days ago, via pip's --uploaded-prior-to flag.

Bug Fixes

• Restored authentication to private indexes when [[source]] URLs use environment-variable placeholders. The GHSA-8xgg-v3jj-95m2 fix moved credentials off pip's argv onto a merged netrc, but write_credentials_netrc wrote our Pipfile-derived machine blocks BEFORE the appended user netrc — and netrc.authenticators() returns the LAST matching entry, so a stale system entry for the same host silently overrode the freshly-expanded creds. Our blocks now come AFTER the user's existing content. Additionally, the pylock.toml reader now runs expand_url_credentials over its sources so users with [pipenv] use_pylock = true see the same env-var expansion that Pipfile.lock reads have always had. [#6670](https://github.com/pypa/pipenv/issues/6670) <https://github.com/pypa/pipenv/issues/6670>_
• Restored documented pipenv update (no args) semantics of lock + sync. Since 2026.0.0, pipenv update only re-resolved Pipfile entries whose locked version no longer satisfied the Pipfile specifier, so relaxing a pin (e.g. urllib3 = "<2.7.0" → urllib3 = "*") would not pick up newer allowed releases — the lockfile silently stayed at the existing pin. pipenv update now routes through do_lock when no packages are given, re-resolving every Pipfile entry. The targeted pipenv update <pkg> path is unchanged. [#6672](https://github.com/pypa/pipenv/issues/6672) <https://github.com/pypa/pipenv/issues/6672>_
