- Several unusual situations that can lead to premature OutOfMemoryError can now be identified and explained
- Improved analysis of DirectByteBuffers
- Improvements in the presentation of thread stacks
- UI improvements and bug fixes
What’s new in version 2.8
- Detection of various common memory problems in JDK classes and popular 3rd party libraries
