+* [CHANGE] Remove vParquet encoding [#3663](https://github.com/grafana/tempo/pull/3663) (@mdisibio)
+  **BREAKING CHANGE** In the last release vParquet (the first version) was deprecated and blocked from writes. Now it is 
+  removed entirely.  It will no longer be recognized as a valid encoding and cannot read any remaining vParquet blocks. Installations
+  running with historical defaults should not require any changes as the default has been migrated for several releases. Installations
+  with storage settings pinned to vParquet must run a previous release configured for vParquet2 or higher until all existing vParquet (1) blocks
+  have expired and been deleted from the backend, or else will encounter read errors after upgrading to this release.
