+### New feature
+- feat(sourcemaps): Multi-project sourcemaps upload (#2497) by @szokeasaurusrex
+   - Sourcemaps can now be uploaded to multiple projects at once by passing each project to the `sentry-cli sourcemaps upload` command, like so:
+     ```sh
+     sentry-cli sourcemaps upload -p project1 -p project2 /path/to/sourcemaps
+     ```
+  - Note that users on old versions of self-hosted Sentry may need to upgrade their self-hosted server to a newer version to take advantage of multi-project uploads.
