Nevertheless, some changes might +be needed after upgrading: +- The utmp daemon has been removed and is not supported by glibc anymore. + If it has been in use, it should be switched off. +- Programs using IPv6 have to be recompiled due to incompatible changes in + sockaddr_in6 by the IPv6 working group. +- The Berkeley db libraries have been removed (for details see ??nssdb). +- The format of the locale files has changed, all locales should be + regenerated with localedef. All statically linked applications which use + i18n should be recompiled, otherwise they'll not be localized. +- glibc comes with a number of new applications. For example ldconfig has + been implemented for glibc, the libc5 version of ldconfig is not needed + anymore. +- There's no more K&R compatibility in the glibc headers.
