 - In the JavaScript API, added multi-project support to `releases.newDeploy()` method. This method now accept a `projects` option (array of project slugs), aligning them with the Rust CLI's multi-project capabilities and matching the existing behavior of `releases.new()` and `releases.uploadSourceMaps()` ([#3001](https://github.com/getsentry/sentry-cli/pull/3001)).
 
+### Improvements
+
+- This release includes some changes to enable support for older self-hosted Sentry versions. With these changes, Sentry CLI now officially self-hosted Sentry versions 24.11.1 and above ([#3070](https://github.com/getsentry/sentry-cli/pull/3070))
+
 ### Fixes
 
 - Fixed a bug that prevented project IDs from being used with the `sentry-cli releases new` command for users with self-hosted Sentry instances on versions older than 25.12.1 ([#3068](https://github.com/getsentry/sentry-cli/issues/3068)).

-Although some Sentry CLI features may work with versions of Sentry Self-Hosted prior to 25.11.1, we recommend users upgrade their self-hosted installations to a compatible version.

-For users who cannot upgrade their self-hosted installation, we recommend using the latest compatible Sentry CLI version, per the table below:
+For self-hosted installations, only those features which were available in Sentry CLI at the time of the release of the given self-hosted version are supported, as new features may require server-side support. Additionally, some features, like the `sentry-cli build` commands, are restricted to Sentry SaaS.

+Users who are using Sentry Self-Hosted versions older than 24.11.1 are encouraged to upgrade their Sentry Self-Hosted installations before using Sentry CLI versions 3.0.0 and above. For users who cannot upgrade, please use the version indicated in the table below.
