FreeBSD CI Weekly Report 2020-09-06
===================================

Here is a summary of the FreeBSD Continuous Integration results for the period
from 2020-08-31 to 2020-09-06.

During this period, we have:

* 2089 builds (92.0% (+3.7) passed, 8.0% (-3.7) failed) of buildworld and
  buildkernel (GENERIC and LINT) were executed on aarch64, amd64, armv6,
  armv7, i386, mips, mips64, powerpc, powerpc64, powerpcspe, riscv64,
  sparc64 architectures for head, stable/12, stable/11 branches.
* 237 test runs (42.6% (-2.7) passed, 24.5% (-3.2) unstable, 32.9% (+5.9)
  exception) were executed on amd64, i386, riscv64 architectures for head,
  stable/12, stable/11 branches.
* 30 doc and www builds (100% passed)
