Each entry carries a release number, a date and the release notes of everything that changed for you, grouped by where you notice it: **Platform**, **Secure environment**, **Python SDK**, **CLI** and **Docs**. A collapsed block at the end of every entry lists the Helm chart, CLI, Python SDK and data ingestor versions the release corresponds to, so you can tell which of them to update. **How the number moves.** The middle number (`0.19.0` to `0.20.0`) moves when a release changes something you can notice. The first number moves when a compatibility floor or an install-time contract changes: read those entries first, they name what you have to do. Releases that change nothing for you are not listed here. **Where to act.** When an entry asks you to update something: * the secure environment updates itself by default; to update by hand or pin a version, follow [Upgrade](/environment-setup/operations#upgrade), or [roll back](/environment-setup/operations#roll-back) if you have to * update the tracebloc CLI with the one-liner under [Install](/environment-setup/cli#install) * update the Python SDK as described under [Installation](/tools-help/tracebloc#installation) * setting up a new secure environment starts at the [Quick Start](/environment-setup/quickstart) **Follow releases.** Every entry on this page is also published as an RSS item at `https://docs.tracebloc.io/changelog/rss.xml`; the RSS button at the top of this page links the same feed. Filter the entries by surface with the tags in the side panel. No release is listed yet. Entries appear here with the first release that changes something for you.
