Changelog

0.3.6 (June 17th, 2011)

  • fix bug in Time/DateTime range detection
  • (win32) fix bug where the Mysql2::Client object wasn't cleaned up properly if interrupted during a query
  • add Mysql2::Result#count (aliased as size) to get the row count for the dataset this can be especially helpful if you want to get the number of rows without having to inflate the entire dataset into ruby (since this happens lazily)

0.3.5 (June 15th, 2011)

  • bug fix for Time/DateTime usage depending on 32/64bit Ruby

0.3.4 (June 15th, 2011)

  • fix a long standing bug where a signal would interrupt rb_thread_select and put the connection in a permanently broken state
  • turn on casting in the ActiveRecord again, users can disable it if they need to for performance reasons

0.3.3 (June 14th, 2011)

  • disable async support, and access to the underlying file descriptor under Windows. It's never worked reliably and ruby-core has a lot of work to do in order to make it possible.
  • added support for turning eager-casting off. This is especially useful in ORMs that will lazily cast values upon access.
  • added a warning if a 0.2.x release is being used with ActiveRecord 3.1 since both the 0.2.x releases and AR 3.1 have mysql2 adapters, we want you to use the one in AR 3.1
  • added Mysql2::Client.escape (class-level method)
  • disabled eager-casting in the bundled ActiveRecord adapter (for Rails 3.0 or less)

0.3.2 (April 26th, 2011)

  • Fix typo in initialization for older ActiveRecord versions
