+# 0.2.0 - (*2022-11-20*)
+
+### Notable changes  
+### 0.1.0 -> 0.2.0
+
+Version 0.2.0 is obviously a massive overhaul with far more changes than the changelog indidicates from 0.1.0.
+This is due to several factors and not doing any type of regular releases.
+
+Development is rather ad-hoc and small updates but with the huge upgrade from gitlab and kubernetes, a minor 
+release feels appropriate.
+
+Going forward and as the project matures, the CHANGELOG.md will play a more important role.
+
+That being said, some notable things below with many unlisted:
+
+- Convert 95+% script based provisioning into ansible
+- Upgrade to ubuntu lts 22.04 for Digital Ocean
+- Upgrade gitlab to 15.5.3
+- Upgrade kubernetes to 1.24.7
+- Deprecate shell runners except for build servers
+- Deprecate cert-based gitlab integration for agent-based integration
+- Add Digital Ocean cloud volume support
+  - AWS will be soon to follow, Azure eventually
+- Add buildkitd pod for in-cluster docker builds
+- Add helm, skaffold, and buildctl to gitlab k8s runner image
+- Add basic azure support
+- Add mongoDB clustering logic
+  - All databases will soon be project/container based however
+- Add alpha stage implentation for managed_kubernetes
