Ubuntu Glibc News


Groovy Gorilla (20.10) has just been released shipping glibc 2.32 [1]
bringing many new and also numerous deprecated features. The
deprecations such as the removal of Sun RPC and NIS development files
are partially mitigated by adding rpcsvc-proto, libtirpc-dev and
libnsl-dev to libc6-dev's dependencies to minimize the number of
packages failing to build in 20.10. Eventually those dependencies will
be dropped thus if you discover that a package build relies on files
not shipped in libc6-dev anymore please add the new build-dependency

If you would like to offer a Ubuntu-specific patch for glibc you are
welcome to file merge proposals against the new glibc packaging
repository [2].

Focal Fossa (20.04 LTS) has recently received a glibc update [3]
improving support for the POWER10 [4] architecture and working around
a limitation that prevented upgrading to and using 20.04 LTS in many
ways on WSL1 [5] (WSL2 did not have this limitation).

Bionic Beaver (18.04 LTS) is about to receive a glibc update [6]
including a vast amount of stability and performance fixes by merging
all of upstream's back-ported changes for 2.27 [7]. The update also
adds a new binary package, libc6-lse on arm64 for optimized
performance on systems supporting the large-system extensions (LSE)
