Greetings all, More than just a new version Finally we have time to celebrate the release of Subrion CMS 4.x branch. We will still support Subrion CMS 3.3.5 anyhow we will release the new functionality for our new version branch only, Subrion 3.3.5 will only have minor bug fixes. Since it's a major release, there is something special that we prepared for you. Subrion 4 is something we've been working on for the past several months and finally we're are proud to share the results with you. Here is the list of the most significant changes. Migrating to new Bootstrap 3 Keeping two different frameworks in the system would be a strain on development and support, not to mention confusing. So we're not just deprecating the old templates framework, we're removing it entirely and will migrate some of our templates & plugins to the new framework, which is based on Bootstrap 3. This means more flexibility, mobile-friendlyness, and less loading time for your websites. Good catch, isn't it? Better performance Every new release of Subrion is faster than the last, but in this release we did something special. We removed a lot of legacy code which existed in our software since its birth. We added more and more functionality in each release to make the software more abstract, so the development could be easier and faster. Sometimes, we had to keep the obsolete functionality to have plugins compatible with the new version. This is something we sacrify in 4.0 in favor of a faster and stable code. Github development We made the major step in becoming more open to the public. Now you can see the core development progress on Github and take part in the development. We would be happy to see you joining our forces to make the software better. Fork us and contribute your stuff! There are some contribution guidelines for you though. You should also report your issues to github. Every plugin has its own repository now. Semantic versioning Sometimes Subrion versioning system is a pain to understand. So this is something we finally take care of since 4.x version. Given a version number MAJOR.MINOR.PATCH, increment the: MAJOR version when you make incompatible API changes, MINOR version when you add functionality in a backwards-compatible manner, and PATCH version when you make backwards-compatible bug fixes. Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.
