-[6.0alpha5]
-===========
+== [6.0alpha5] ==

asm. Some versions of gcc apparently optimize away writes to local volatile
line.
-[6.0alpha4]
-===========
+== [6.0alpha4] ==
* Moved up the detection of mostly full blocks to the initiation of the
sweep phase. This eliminates some lock contention in the PARALLEL_MARK case,
* Made it possible (with luck) to redirect malloc to GC_local_malloc.
-[6.0alpha3]
-===========
+== [6.0alpha3] ==
* Fixed the /proc/self/maps code to not seek, since that apparently is not
reliable across all interesting kernels.
To turn it on, define SAVE_CALL_CHAIN.

* There were lots of spurious leak reports in leak detection mode, caused
around a Windows 95 GetOpenFileName problem.
-[5.2]
-=====
+== [5.2] ==
* dyn_load.c declared GC_scratch_last_end_ptr as an extern even if it

adding as a standard facility.
-[4.11]
-======
+== [4.11] ==
* Rationalized (hopefully) GC_try_to_collect in an incremental collection
environment. It appeared to not handle a call while a collection was in
environments.
-[4.10]
-======
+== [4.10] ==
* Fixed a typo around a call to GC_collect_or_expand in alloc.c. It broke
handling of out of memory.
