+## [2.0.0.beta1] - 2023-09-08
+### Added
+- The gem now comes bundled with the underlying re2 library and its dependency,
+  abseil. Installing the gem will compile those dependencies automatically. As
+  this can take a while, precompiled native gems are available for Linux,
+  Windows and macOS. (Thanks to Stan Hu for contributing this.)
+
+### Changed
+- By default, the gem will use its own bundled version of re2 rather than
+  looking for the library on the system. To opt back into that behaviour, pass
+  `--enable-system-libraries` when installing. (Thanks to Stan Hu for
+  contributing this.)
+
+### Removed
+- Due to the new dependency on MiniPortile2, the gem no longer supports Ruby
+  versions older than 2.7.
