High Level Milestones

Milestones	JIRA ID	Owner	Target Completion	Comments
Primitive rendering		Oracle/JetBrains		Implementation is done
Image rendering		JetBrains		Implementation is done (except for Bicubic interpolation - for which SW rendering fallback exists)
Text rendering		Oracle		Implementation is done
1st early access (EA-1)		Oracle/JetBrains	15 May 2020	Released
Stabilization and bug fixing		Oracle/JetBrains		In progress
IDE performance Testing		Oracle/JetBrains	TBD
Execute JTREG tests and match current passrate		Oracle	TBD	Metal pipeline should pass all the same jtreg tests as OpenGL : i.e. no functional regressions
Pass all JCK tests		Oracle	TBD
Functional complete with performance		Oracle/JetBrains	TBD
2D Alias Review Start		Oracle/JetBrains	TBD	Lanai does not require reviews before pushing. Once we are functional complete, we should start reviews of the code to make sure it conforms to style/quality/etc expectations, as well as reviewing the code for correctness, robustness etc.
