* 3.5.0 (XXX)
+ This version focuses on refactoring and automated testing, though it also
+ includes some non-trivial heap profiling optimizations not mentioned below.
+
+ New features:
+ - Add the *allocx() API, which is a successor to the experimental *allocm()
+ API. The *allocx() functions are slightly simpler to use because they have
+ fewer parameters, they directly return the results of primary interest, and
+ mallocx()/rallocx() avoid the strict aliasing pitfall that
+ allocm()/rallocx() share with posix_memalign(). Note that *allocm() is
+ slated for removal in the next non-bugfix release.
+ - Add support for LinuxThreads.
+
Bug fixes:
- Unless heap profiling is enabled, disable floating point code and don't link
with libm. This, in combination with e.g. EXTRA_CFLAGS=-mno-sse on x64

point registers during dynamic lazy symbol loading, and the symbol loading
code uses whatever malloc the application happens to have linked/loaded
with, the result being potential floating point register corruption.
+ - Report ENOMEM rather than EINVAL if an OOM occurs during heap profiling
+ backtrace creation in imemalign(). This bug impacted posix_memalign() and
+ aligned_alloc().
+ - Fix a file descriptor leak in a prof_dump_maps() error path.
+ - Fix prof_dump() to close the dump file descriptor for all relevant error
+ paths.
+ - Fix rallocm() to use the arena specified by the ALLOCM_ARENA(s) flag for
+ allocation, not just deallocation.
+ - Fix a data race for large allocation stats counters.
+ - Fix a potential infinite loop during thread exit. This bug occurred on
+ Solaris, and could affect other platforms with similar pthreads TSD
+ implementations.
+ - Don't junk-fill reallocations unless usable size changes. This fixes a
+ violation of the *allocx()/*allocm() semantics.
+ - Fix growing large reallocation to junk fill new space.
+ - Fix huge deallocation to junk fill when munmap is disabled.
- Change the default private namespace prefix from empty to je_, and change
--with-private-namespace-prefix so that it prepends an additional prefix
rather than replacing je_. This reduces the likelihood of applications
which statically link jemalloc experiencing symbol name collisions.
+ - Add missing private namespace mangling (relevant when
+ --with-private-namespace is specified).
+ - Add and use JEMALLOC_INLINE_C so that static inline functions are marked as
+ static even for debug builds.
+ - Add a missing mutex unlock in a malloc_init_hard() error path. In practice
+ this error path is never executed.
+ - Fix numerous bugs in malloc_strotumax() error handling/reporting. These
+ bugs had no impact except for malformed inputs.
+ - Fix numerous bugs in malloc_snprintf(). These bugs were not exercised by
+ existing calls, so they had no impact.
