|
|
|

|
* (As the version-number jump hints, this is a major new release: |

|
* Support for recent kernel ABI changes (e.g. new arg to mremap) |

|
* Several new unittests to test, e.g., thread-contention costs |
|
* Lots of small (but important!) bug fixes: e.g., fixing GetPC on amd64 |
|
*** KNOWN PROBLEMS: |
|
* CPU-profiling may crash on x86_64 (64-bit) systems. See the README |
|
* Profiling/heap-checking may deadlock on x86_64 systems. See README |
