flox/flox v1.19.0 was published on 2026-10-20.

This PR adds the changelog entry for the release. The copy was drafted by Muse Spark (muse-spark-1.3-contributor, through the Meta Model API) from the release notes, and no person has edited it yet. Review it like any other docs change, then approve and merge. To change the wording, push to this branch; the workflow never regenerates an open PR. If this release doesn't merit a changelog entry, close the PR and it won't be recreated.

What to check

• Every claim matches the release notes, with nothing invented or overstated.
• The ## sections cover the changes that matter most to users.
• Each "See ..." link lands on the page and section it describes.
• Wording follows the terminology and style in AGENTS.md.

Automated checks

• 3 internal link(s) resolve to pages and headings in this repo.
• No problems found, so this PR opened ready for review.

Notes from the model

• Chose auth requirement, per-group stability, and flox list --all as the three headlines; moved other auth prompts, package selection, Docker fix, and activation race fix to Also.
• Omitted flox search and flox services status tabular alignment as minor formatting.
• Omitted login compatibility versions (1.3.5+ and 1.14.0+) and the https://go.flox.dev/auth details link to fit the sentence limit and external-link rules.
• Kept the concurrent-activation race fix without contributor attribution per style.
• No docs page found for auth-enforcement timing; linked the Authentication concept page. Stability links to package-groups choosing-a-stability rather than manifest.toml.
