The first long-term release (LTR) of QGIS 3. This is a giant leap forward for the project - our first Long Term Release based on the 3.x platform. For users moving over from the 2.18 LTR there is a huge list of new features and impactful changes in this new LTR version. Please bear in mind that 3.x plugins are incompatible with 2.x plugins so review your plugin usage carefully - and if possible help to migrate old plugins to the new platform. If you have not already done so, take a look at the changelogs from Version 3.0 and Version 3.2 to understand the full scope of changes in the 3.0 release.
