1.5.2

2011-12-13

1.5.1

2011-11-29

Release due to corrupted gemspec. This was a bug having to do with rubygems. Apparently, gems must still be built with Ruby 1.8.

1.5.0

2011-11-28

This releases fixes bugs introduced in 1.4.0 and 1.4.1 that were introduced as a result of adding replica set refresh modes.

  • Removed :async refresh mode.
  • Disabled auto refresh mode by default. If you want the driver to automatically check the state of the replica set, you must use :sync mode. Note that replica set refresh is designed only to account for benign changes to the replica set (adding and removing nodes that don't affect current connections).
  • Fixed bug with commands being sent to secondary nodes. The next release will allow you to specify where commands can be sent.
  • Support :j safe mode option.
  • Fix :max_scan and :show_disk_loc Cursor options.

You can see the remaining issues at https://jira.mongodb.org/secure/ReleaseNote.jspa?projectId=10005&version=10992
