With the release upcoming we've switched to reviewing blockers and desirable changes.

 * NEW/NOBODY 290 patches
 * [v7] elf: Properly align all PT_LOAD segments [BZ #28676]
  * Adhemerval to review alignment patch.
 * linux: Fix ancillary 64-bit time timestamp conversion (BZ #28349, BZ #28350)
  * Florian to review.
 * posix: Add terminal control setting support for posix_spawn
  * Carlos to finish review Monday.
 * Multiple rtld-audit fixes
  * Adhemerval to rebase patch set.
  * Szabolcs looked at the aarch64 pieces and gave feedback.
 * Properly handle --disable-default-pie
  * Siddhesh is going to look at this.
 * Carlos and Adhemerval discussed 64-bit time_t testing.
  * No way to change library default time_t size, just testing can test it.
 * Prelink discussion
  * Adhemerval: May I submit patches to remove prelink?
  * Carlos: Yes.
  * Discussed Intel, Arm, Linaro involvement in prelink.
  * Carlos: IHVs and ISVs need to invest upstream if they want to see prelink maintained.
 * Paul sends his regrets and includes two items:
  * I have done a review of the accuracy of the libmvec functions (in master)
    both with sse4.2, avx2 and avx512. Apart from a minor issue with atan2
    in binary64 which was fixed (#28765), I found no error larger than 4 ulps,
    both in binary32 and binary64. 
  * we are making good progress in the CORE-MATH project: 17 out of 26
    functions are now available in single precision (binary32).
    See https://homepages.loria.fr/PZimmermann/CORE-MATH/.
    In most cases the correctly-rounded CORE-MATH code outperforms the
    GNU libc one (see the "perf" graphs). The only exceptions so far are
    the cosf function on i7, and the expf function.
