+* 3.6.0 (March 31, 2014)
+
+ This version contains a critical bug fix for a regression present in 3.5.0 and
+ 3.5.1.
+
+ Bug fixes:
+ - Fix a regression in arena_chunk_alloc() that caused crashes during
+ small/large allocation if chunk allocation failed. In the absence of this
+ bug, chunk allocation failure would result in allocation failure, e.g. NULL
+ return from malloc(). This regression was introduced in 3.5.0.
+ - Fix backtracing for gcc intrinsics-based backtracing by specifying
+ -fno-omit-frame-pointer to gcc. Note that the application (and all the
+ libraries it links to) must also be compiled with this option for
+ backtracing to be reliable.
+ - Use dss allocation precedence for huge allocations as well as small/large
+ allocations.
+ - Fix test assertion failure message formatting. This bug did not manifect on
+ x86_64 systems because of implementation subtleties in va_list.
+ - Fix inconsequential test failures for hash and SFMT code.
+
+ New features:
+ - Support heap profiling on FreeBSD. This feature depends on the proc
+ filesystem being mounted during heap profile dumping.
+
* 3.5.1 (February 25, 2014)
This version primarily addresses minor bugs in test code.
