Description

Cut the 1.31.0 release.

• Bump the version from 1.30.1 to 1.31.0.
• Move the [Unreleased] entries under a [1.31.0] heading dated 2026-11-11.
• Add the [1.30.1] - 2026-10-28 section that the 1.30.1 release (chore(no-ticket): pushing 1.30.1 release #566) left out. Its entries sat under [Unreleased] with the 1.31.0 ones. I sorted each entry by checking whether its PR is in the v1.30.1 tag.
• Put the fixes back under ### Fixed. On master, that heading was missing after the deprecation table, so every fix showed under ### Deprecated.
• Add the PR number to every entry.
• Rewrite the feat(no-ticket): use /usr/bin/env sh as shebang for credential helpers on UNIX #586 shebang entry so it says what changes for users.
• Add an entry for fix(no-ticket): bumping python runtime versions to expedited security patches #565 under 1.30.1: the binaries and the Docker image use Python 3.14.10 (the eMudhra CA fix), and the minimum certifi is 2026.10.23.

What 1.31.0 adds, in short:

• cloudsmith credential-helper install maven, gradle and sbt (feat(ENG-15139): set up the Cloudsmith Maven tools for Maven, Gradle, and sbt #520).
• cloudsmith upstream skills, plus --changelog and --compress on cloudsmith push skills (feat(ENG-15434): Add skills upstream command #575, feat(ENG-15336, ENG-15560): Add changelog option to AI Skills package push, and zip support for directories on push #564).
• push skills --compress leaves out .git, .env and OS clutter, and refuses symbolic links (fix(ENG-15593): Add dot and sensitive file filtering pattern to skills compressed push #599).
• Deprecation warnings for the old names of renamed options, environment variables and config keys. Version 2.0.0 removes them (feat(ENG-15245): warn when deprecated option, env var and config names are used #574).
• Many fixes to the credential helpers, the network timeouts and retries, and error handling.
