# Release policy In the GnuTLS project there are at most two ongoing releases, one marked as 'stable' and one marked as 'next'. The former is always present and supported, while the latter is introduced on the discretion of the development team. For both release branches all the rules in [CONTRIBUTING.md](CONTRIBUTING.md) apply, but in principle the 'stable' release is more conservative in new features, while the 'next' branch allows for mild behavioral changes. The 'stable' branch always provides API and ABI compatibility, while the 'next' branch may on exceptional cases change the API. |Branch|Version|Release interval| |:----:|:-----:|:--------------:| |stable|3.6.x |as needed | |next |3.7.x |bi-monthly |
