We are happy to announce the release of Brian 2.2. This release includes a number of important fixes and performance improvements. It also makes sure that simulation no longer give platform-dependent results for certain corner cases that involve the division of integers. For a full list of changes, see the release notes. We recommend all users of Brian 2 to update.
