Hi all. I've just tagged gperftools 2.17.
We have had a few relatively simple updates since the RC release.
* Salvatore Dipietro has contributed SB instruction support for spinlock delay loops on newer ARMs.
* libgcc backtrace capturing method now handles deep backtraces better.
* PPC+musl users can now workaround some issues building PPC-specific backtrace code by adding TCMALLOC_DISABLE_PPC_FRAME_POINTER_BACKTRACER preprocessor define. Much thanks to Josef Schlehofer for reporting the problem. See details in #1602.
* Jackie Cui has contributed a small change to the page heap span selection logic that makes a big difference in reducing the amount of used memory in some workloads. See #1604 for further details.
Much thanks to all the contributors.
You can find the list of all GitHub issues fixes in this release here: https://github.com/gperftools/gperftools/issues?q=label%3Afixed-in-2.17+is%3Aclosed
