A stable release of our software is our reference implementation, at the date of that release, of all the capabilities which, we feel, are well tested and constitute a solid basis for your internal use of our software. When a new stable release is made available, you should always upgrade and make it your current installation. If and as users report problems, these are posted onto the Issues page for that stable release.

We recognise, however, that upgrading to a new release may be impeded by certain activation barriers in corporate or institutional environments, making it difficult to keep up with rapid successions of stable releases that would address these issues one by one.

Snapshot releases are intended to provide a mechanism for more frequent and more regular incremental updates of our software that may not warrant the effort of an upgrade for all users at all stages. They are meant to be fully functional, but they may contain first implementations of new features, improvements to existing ones, or bug fixes that are still more tentative than in a stable release. In case of problems, the stable release is intended as a fall-back. You should therefore make sure that you do not remove or overwrite installations of stable releases on your systems when installing snapshots releases.

We do our best to ensure that the Release Notes accompanying snapshot releases give a detailed description of the changes made, in close relation to the Issues page for the previous stable release, to enable the user to decide whether or not these changes warrant an upgrade to that latest snapshot version.
