* 3.3.0 (January 23, 2013)
|
||||
|
||||
This version includes a few minor performance improvements in addition to the
|
||||
listed new features and bug fixes.
|
||||
|
||||
New features:
|
||||
- Add clipping support to lg_chunk option processing.
|
||||
- Add the --enable-ivsalloc option.
|
||||
- Add the --without-export option.
|
||||
- Add the --disable-zone-allocator option.
|
||||
|
||||
Bug fixes:
|
||||
- Fix "arenas.extend" mallctl to output the number of arenas.
|
||||
- Fix chunk_recycyle() to unconditionally inform Valgrind that returned memory
|
||||
is undefined.
|
||||
- Fix build break on FreeBSD related to alloca.h.
|
||||
|
||||
* 3.2.0 (November 9, 2012)

Don't export public APIs. This can be useful when building jemalloc as a

static library, or to avoid exporting public APIs when using the zone

--enable-ivsalloc

Enable validation code, which verifies that pointers reside within

performance hit.

Disable zone allocator for Darwin. This means jemalloc won't be hooked as

the default allocator on OSX/iOS.

--enable-utrace

Enable utrace(2)-based allocation tracing. This feature is not broadly
