The contest was extended until the end of the final vote and approval of a 10.2 release. Voting for ended successfully October 5th, and the 10.2 Regression Search and Destroy Contest is thereby closed. Judges will announce the winners shortly.

The Derby 10.2 Regression Search and Destroy Contest is a contest to help ensure a smooth transition for users who are migrating to 10.2 and help achieve Derby's Forward Compatiblity goal: to to allow any application written against the public interfaces of an older version of Derby to run, without any changes, against a newer version of Derby.

Contest entries can be anything to help ease transition of existing applications to 10.2. Winners will be:

The Rules

1. Valid contest entries are any action that exposes or resolves existing regressions, improves Derby compatibility with previous releases, or improves our documentation of known differences in 10.2. Below are a few examples:

2. Bugs filed against or fixed for new functionality does not count for the contest but are of course welcome.

3. Three winners are chosen by impartial judge(s) based on entries completed by the end of the final vote and approval of a 10.2 Release Candidate.. Stan Bradbury, Rajesh Kartha and John Embretsen are our judges and can meet on #derby IRC after September 15 to discuss who the winners are.

4. The winners get organic chocolate and of course glory, kudos and huge amounts of merit. (Contribution of other prizes is welcome, but wouldn't want to make the stakes so high the lawyers need get involved).
