- **fixed** — Backed out the expat library update that caused memory inflation and browser hang issues on XUL/XML and SVG files with particularly large attributes
- **fixed** — Backed out the change of the Javascript PRNG that caused intermittent issues and crashes on 32-bit platforms

This is a minor release to address some critical issues in the new milestone.

**Changes/fixes:**

- Backed out the expat library update for causing memory inflation and browser hang issues on XUL/XML and SVG files with particularly large attributes.
- Backed out the change of the Javascript PRNG for causing intermittent issues and crashes on 32-bit platforms.

Both of these issues are being investigated and can hopefully re-land with the next development release.
