This release contains all of the same code and therefore release notes as 0.3.12.
The following changes are specific to 0.2.19:
- The EventMachine ActiveRecord adapter and EM Fiber driver have been removed. You should use https://github.com/igrigorik/em-synchrony instead as it's being maintained there.
- The ActiveRecord adapter now symbolizes the keys from the connection options hash as early as possible to ensure hash lookups on that hash will work before the
Mysql2::Clientobject is created.
- Make sure a default LIMIT is set when an OFFSET is set.
- A couple of small fixes related to newer ActiveRecord versions since the last mysql2 release
