The major changes in this release are:
- MySQL's MyISAM support has been dropped. Use InnoDB instead.
- The editor for static pages now highlights the content's markup and displays
a live preview.
- Added support for Elasticsearch-based external Translation Memory servers.
- Changed connection logic and added checks for misconfigured Translation
Memory servers.
- Significant speed up when importing files.
The release notes are available in [Pootle documentation](http://docs.translatehouse.org/projects/pootle/en/stable-2.7.3/releases/2.7.3b1.html).
