 ### Added
 
+- The SQLITE_DBPAGE extension is now enabled by default, which implements an eponymous-only virtual table that provides direct access to the underlying database file by interacting with the pager. See https://www.sqlite.org/dbpage.html for more information. [#578] @flavorjones
 - `Database#optimize` which wraps the `pragma optimize;` statement. Also added `Constants::Optimize` to allow advanced users to pass a bitmask of options. See https://www.sqlite.org/pragma.html#pragma_optimize. [#572] @alexcwatt @flavorjones
 - `SQLite3::VERSION_INFO` is a new constant that tracks a bag of metadata about the gem and the sqlite library used. `SQLite3::SQLITE_PACKAGED_LIBRARIES` and `SQLite3::SQLITE_PRECOMPILED_LIBRARIES` are new constants indicating how the gem was built. [#581] @flavorjones
