glibc (2.32-0experimental1) experimental; urgency=medium
The libc0.3-xen and libc6-xen packages have been removed in this version,
due to the removal of the "nosegneg" support from glibc and due to the
removal of 32-bit Xen PV support from Linux kernel 5.9. PVH or PVHVM guests
should be used instead.

glibc (2.31-5) unstable; urgency=medium
Starting with glibc 2.31-5, the NIS and NIS+ name service modules
libnss_nis.so.2.0.0 and libnss_nisplus.so.2.0.0 are not provided anymore by
the libc6 package. People needing those modules have to install the
libnss-nis and/or the libnss-nisplus packages, which are recommended by
the libc6 package.

glibc (2.31-0experimental2) experimental; urgency=medium
Starting with glibc 2.31, the DNS stub resolver does not blindly trust the
AD (authenticated data) flag, indicating a DNSSEC validation:
- By default the name servers and the network path to them are treated as
untrusted. In this mode, the AD flag is not set in queries, and it is
automatically cleared in responses, indicating a lack of DNSSEC
validation.
- A new trust-ad option, set via the options directive in /etc/resolv.conf
(or if RES_TRUSTAD is set in _res.options), indicates that the name
server is trusted. In this mode, the AD bit, as provided by the name
server, is made available to the applications.
Therefore if you trust your name servers, for example because you use a
locally running validating resolver (e.g. unbound, systemd-resolved or
dnsmasq), you might want to add the following line to /etc/resolv.conf:
options trust-ad

glibc (2.26-5) unstable; urgency=medium
Starting with version 2.26-1, the glibc requires a 3.2 or later Linux
kernel. If you use an older kernel, please upgrade it *before*
installing this glibc version. Failing to do so will end-up with the
following failure:
Preparing to unpack .../libc6_2.26-5_amd64.deb ...
ERROR: This version of the GNU libc requires kernel version
3.2 or later. Please upgrade your kernel before installing
glibc.
The decision to not support older kernels is a GNU libc upstream
decision.
Note: This obviously does not apply to non-Linux kernels.

eglibc (2.13-25) unstable; urgency=medium
Starting with the eglibc package version 2.13-5, the libraries are
shipped in the multiarch directory /lib/<triplet> instead of the more
traditional /lib, where <triplet> is the multiarch triplet and can be
retrieved with 'dpkg-architecture -qDEB_HOST_MULTIARCH'. Similarly the
includes are now shipped in /usr/include/<triplet> instead of the more
traditional /usr/include.
The toolchain in Debian has been updated to cope with that, and most
build systems should be unaffected. If you are using a non-Debian
toolchain to build your software and it is not able to cope with
multiarch, you might try to pass the following options to your
compiler:
-B/usr/lib/<triplet> -I/usr/include/<triplet>
Alternatively if the build system makes hard to pass the above options,
you might try to set the LIBRARY_PATH and CPATH environment variables:
LIBRARY_PATH=/usr/lib/<triplet>
CPATH=/usr/include/<triplet>
export LIBRARY_PATH CPATH

glibc (2.9-8) unstable; urgency=low
Starting with version 2.9-8, unified IPv4/IPv6 lookup have been enabled
in the glibc's resolver. This is faster, fixes numerous of bugs, but is
problematic on some broken DNS servers and/or wrongly configured
firewalls.
If such a DNS server is detected, the resolver switches (permanently
for that process) to a mode where the second request is sent only when
the first answer has been received. This means the first request will
be timeout, but subsequent requests should be fast again. This
behaviour can be enabled permanently by adding 'options single-request'
to /etc/resolv.conf.

glibc (2.6.1-2) unstable; urgency=low
Starting with version 2.6.1, glibc ships a /etc/ld.so.conf.d/libc.conf that
enforces /usr/local/lib to take precedence over /usr/lib. This is the
intended behaviour (it works like the $PATH where /usr/local/bin takes
precedence over /usr/bin).
To revert that (though doing so is discouraged) you can add /usr/lib to the
beginning of /etc/ld.so.conf.d/libc.conf. (see bug#440394).

glibc (2.5-1) unstable; urgency=low
The script tzconfig has been removed from glibc 2.5-1 and following
versions. Please use 'dpkg-reconfigure tzdata' instead to configure
the timezone.

glibc (2.5-1) unstable; urgency=low
Starting with version 2.5-1, the glibc requires a 2.6.1 or later
kernel. If you use a 2.4 kernel, please upgrade it *before*
installing glibc.
This also means that it is not possible to use LD_ASSUME_KERNEL with a
version lower than 2.6.1. If you have set such a thing in /etc/profile,
~/.bashrc or any other initialization file (something you should have
never done!!!), please remove that *before* installing glibc.
Note: This does not apply to the m68k architecture and to non-Linux
kernels.
