This errata document contains “late-breaking news” about FreeBSD 11.4-RELEASE. Before installing this version, it is important to consult this document to learn about any post-release discoveries or problems that may already have been found and fixed.
Any version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the “current errata” for this release.

[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.
