[christianwimmer]

List of all past and upcoming meetings: #3933

New and Noteworthy

• The option --initialize-at-build-time without specifying a package/class name was already deprecated for more than a year. Now it is an error to use it: [GR-41978] Disallow --initialize-at-build-time without arguments. #5266

• JVMCI changes, avoid dependencies on HotSpot specific JVMCI classes.
  Step 1: clean up HotSpot JVMCI dependencies: [GR-41921] Centralize and reduce usage of HotSpot JVMCI internals. #5313
  Step 2: Improve JVMCI, e.g., JDK-8296958, JDK-8296960, JDK-8296961
  Step 3: Use the new JVMCI functionality: [GR-41977] Adapt to JVMCI API changes. #5455

• Improve precision of the static analysis:
  [GR-41674] Class instanceOf and isAssignableFrom checks do need to make the checked type reachable. #5224
  [GR-42250] Class constants should not make types reachable during bytecode parsing. #5438
  [GR-29145] Points-to analysis constant propagation in default policy. #5346
  [GR-29145] Strengthen graphs with constants propagated through static analysis. #5454

• Improve the traceability of the static analysis: [GR-41279] Add reason for AnalysisType instantiation. #5453

• Usability improvements: [GR-41912] More user-friendly reporting of internal errors. #5414

• Initial work on a parallel version of the stop&copy GC: [WIP] Parallel garbage collector #5362

• Monitoring / tools:
  [GR-42531] Debug info memory footprint improvements #5436
  [GR-40463] Add initial support for JMX to Native Image #4786
  [GR-41196] Provide .debug.* sections that contain build options and properties used in the build of an image. #5254
