14 - Fix xallocx(..., MALLOCX_ZERO) to zero trailing bytes of huge allocations
15 when resizing from/to a size class that is not a multiple of the chunk size.
16 - Fix prof_tctx_dump_iter() to filter out nodes that were created after heap
23 This bugfix release addresses a few bugs specific to heap profiling.
26 - Fix ixallocx_prof_sample() to never modify nor create sampled small
29 - Fix irallocx_prof_sample() to always allocate large regions, even when
31 - Fix prof_alloc_rollback() to read tdata from thread-specific data rather
36 This is a bugfix release that is somewhat high risk due to the amount of
37 refactoring required to address deep xallocx() problems. As a side effect of
38 these fixes, xallocx() now tries harder to partially fulfill requests for
41 fixes that were integral to disovering most of the other bugs.
48 - Optimize irallocx_prof() to optimistically update the sampler state. The
49 prior implementation appears to have been a holdover from when

59 - Fix chunk purge hook calls for in-place huge shrinking reallocation to

75 + Fix prof_realloc() to call prof_free_sampled_object() after calling
76 prof_malloc_sample_object(). Prior to this fix, if tctx and old_tctx were
82 + Rename index_t to szind_t to avoid an existing type on Solaris.
83 + Add JEMALLOC_CXX_THROW to the memalign() function prototype, in order to

99 - Normalize size class spacing to be consistent across the complete size
103 --with-lg-tiny-min options, which can be used to tweak page and size class
108 + Internal fragmentation is limited to 20% for all but the smallest size
111 + Chunk fragmentation tends to be lower because there are fewer distinct run
112 sizes to pack.
115 MALLOCX_TCACHE(tc) and MALLOCX_TCACHE_NONE flags to the *allocx() API

243 - Fix tls_model configuration to enable the initial-exec model when possible.

260 libraries it links to) must also be compiled with this option for
261 backtracing to be reliable.
277 - Configure Solaris/Illumos to use MADV_FREE.
297 - Add the *allocx() API, which is a successor to the experimental *allocm()
298 API. The *allocx() functions are slightly simpler to use because they have
308 systems, makes it possible to completely disable floating point register
309 use. Some versions of glibc neglect to save/restore caller-saved floating
311 code uses whatever malloc the application happens to have linked/loaded

435 - Auto-detect whether running inside Valgrind, thus removing the need to
437 - Add the "arenas.extend" mallctl, which allows applications to create
446 - Disable tcache by default if running inside Valgrind, in order to avoid
447 making unallocated objects appear reachable to Valgrind.

707 - Fix strerror_r() usage to deal with non-standard semantics in GNU libc.

709 to be underreported (though the reported number of objects and bytes were
712 cause memory corruption, but it was hard to trigger.
714 multiple threads raced to create a new run of backing pages.
715 - Enhance the heap profiler to trigger samples based on usable size, rather
717 - Fix a heap profiling bug due to sometimes losing track of requested object
724 profiling). This bug could cause zero-length backtraces to be reported.
726 threads raced to initialize malloc, some of them could end up permanently
