We're excited to announce that the Clearspace and Clearspace X betas are now part of the release train and will be released every three weeks on the Wednesday directly following when the prior general release is made available. The first beta is available today for version 1.6, just after the final release of 1.5 came out last week.
Please don't use these beta releases in production, and please don't upgrade your production instances to the beta releases. Instead, install the beta as a new installation or use a copy of your production system to try out the beta upgrade. We don't officially support the betas, but would love to get your feedback on them in Jivespace.
