+* 2.2.5 (November 14, 2011)
+
+ Bug fixes:
+ - Fix huge_ralloc() race when using mremap(2). This is a serious bug that
+ could cause memory corruption and/or crashes.
+ - Fix huge_ralloc() to maintain chunk statistics.
+ - Fix malloc_stats_print(..., "a") output.
+
+* 2.2.4 (November 5, 2011)
+
+ Bug fixes:
+ - Initialize arenas_tsd before using it. This bug existed for 2.2.[0-3], as
+ well as for --disable-tls builds in earlier releases.
+ - Do not assume a 4 KiB page size in test/rallocm.c.
+
+* 2.2.3 (August 31, 2011)
+
+ This version fixes numerous bugs related to heap profiling.
+
+ Bug fixes:
+ - Fix a prof-related race condition. This bug could cause memory corruption,
+ but only occurred in non-default configurations (prof_accum:false).
+ - Fix off-by-one backtracing issues (make sure that prof_alloc_prep() is
+ excluded from backtraces).
+ - Fix a prof-related bug in realloc() (only triggered by OOM errors).
+ - Fix prof-related bugs in allocm() and rallocm().
+ - Fix prof_tdata_cleanup() for --disable-tls builds.
+ - Fix a relative include path, to fix objdir builds.
+
+* 2.2.2 (July 30, 2011)
+
+ Bug fixes:
+ - Fix a build error for --disable-tcache.
+ - Fix assertions in arena_purge() (for real this time).
+ - Add the --with-private-namespace option. This is a workaround for symbol
+ conflicts that can inadvertently arise when using static libraries.
+
* 2.2.1 (March 30, 2011)
Bug fixes:
jemalloc overlays the default malloc zone, but makes no attempt to actually
replace the "malloc", "calloc", etc. symbols.
+--with-private-namespace=<prefix>
+ Prefix all library-private APIs with <prefix>. For shared libraries,
+ symbol visibility mechanisms prevent these symbols from being exported, but
+ for static libraries, naming collisions are a real possibility. By
+ default, the prefix is "" (empty string).
+
--with-install-suffix=<suffix>
Append <suffix> to the base name of all installed files, such that multiple
versions of jemalloc can coexist in the same installation directory. For
@objroot@lib/libjemalloc@install_suffix@.$(SO)
