+
+The D7 release cycle
+====================
+
+* One long-running branch
+* Minor versions for bug fixes (7.80, April 2021)
+* No big, new features
+* Long time for changes to get committed to core

+
+The D8 release cycle
+====================
+
+* Semantic versioning for core
+* Minor release (new features) every 6 months
+* Patch release (bug fixes) every month
+* Multiple supported versions of core (8.9, 9.0, 9.1)

+Drupal 8 vs Drupal 9
+====================
+
+* No new functionality

+* Major versions of dependencies updated

+.. raw:: pdf
+
+    TextAnnotation "Different to previous major version updates"

+========
+
+- Dependency management tool for PHP
