Sitecore Experience Platform 9 Update 2 (aka Sitecore XP 9.0.2) was out two months ago. Personally, I wanted to wait for the new release of awesome ones such as Glass.Mapper.Sc version 5, Unicorn version 4.0.4 so that I had a chance to upgrade all of them as well. Finally, my simple Sitecore development framework version 2.2 is out:

• Upgrading to Glass.Mapper.Sc Version 5 (thanks my fellow Sitecore MVP Micheal Edwards)
  • a summary of the changes
  • find out how to upgrade to Glass.Mapper.Sc v5
• Upgrading to Unicorn 4.0.4 (thanks my fellow Sitecore MVP Mark Cassidy)
  • find out the issues and fixes
  • have a look at the new features
  • 
• Upgrading Sitecore References via Nuget from Sitecore XP 9.0.1 to Sitecore XP 9.0.2 ones
  • 
• Upgrading to Sitecore module Custom Icon Injector version 1.1 to make it work properly with Sitecore 9, otherwise you would see something like this
  • 
• Adding a new gulp task Sync-Unicorn-Root-Nodes so that we don’t have to perform Sitecore serialization for non-transparent-sync items such as languages, field types, content editor, the root folders + the layer folders of layouts, templates, renderings, placeholder settings, etc
  • 
• Refining the Sitecore template structure (there are some places violate Helix principles)
• Refining the project templates as well
  • 

Additional one

• Notes for building your own one based on my simple one

Happy Sitecore Coding!
