### Deprecated
- Many things have been deprecated. See [Changes in Craft 3](https://docs.craftcms.com/v3/changes-in-craft-3.html) for a complete list.

### Fixed
- Fixed a bug where a PHP session would be started on every template rendering request whether it was needed or not. ([#1765](https://github.com/craftcms/cms/issues/1765))

### Security
- Craft uses OpenSSL for encryption rather than mcrypt, which is far more secure and well-maintained.
