[2020-06-11] Source-based upgrades from FreeBSD 11.2 on the i386 architecture may fail to compile clang due to the amount of RAM consumed.
Adding CFLAGS+=-O1 to
/etc/make.conf or
/etc/src.conf has been observed to work
around the compile-time RAM
exhaustion.
See PR 246274 for additional details.
[2020-06-16] The FreeBSD 11.4 release notes erroneously state the KDE desktop environment has been updated to version 5.8.4.1.19.12.3. The correct version is 5.18.4.1.19.12.3.
