 - Documentation how to run ED using singularity
 - PEcAn.DB gains new function `get_postgres_envvars`, which tries to look up connection parameters from Postgres environment variables (if they are set) and return them as a list ready to be passed to `db.open`. It should be especially useful when writing tests that need to run on systems with many different database configurations (#2541).
 
+### Removed
+- Database maintenance scripts `vacuum.bety.sh` and `reindex.bety.sh` have been moved to the [BeTY database repository](https://github.com/PecanProject/bety) (#2563).
+- Scripts `dump.pgsql.sh` and `dump.mysql.sh` have been deleted. See the ["BeTY database administration"](https://pecanproject.github.io/pecan-documentation/develop/database.html) chapter of the PEcAn documentation for current recommendations (#2563).
+- Old dependency management scripts `check.dependencies.sh`, `update.dependencies.sh`, and `install_deps.R` have been deleted. Use `generate_dependencies.R` and the automatic dependency handling built into `make install` instead (#2563).
