AwsCli

The 'awscli' package has been retired and replaced with the awscli2. The awscli2 is the most recent major version of the AWS CLI and supports all of the latest features. Some features introduced in version 2 are not backported to version 1 and you must upgrade to access those features. There are some "breaking" changes from version 1 that might require you to change your scripts. For a list of breaking changes in version 2, see Migrating from AWS CLI version 1 to version 2.

LegacyXorgDriverRemoval

perl5.38

  • Core Enhancements

    • New ''class'' feature - new experimental syntax is now available for defining object classes, where per-instance data is stored in "field" variables that behave like lexicals.

    • Unicode 15.0 is supported

    • Deprecation warnings now have specific subcategories - it is still possible to disable all deprecation warnings in a single statement, but now is possible to have a finer grained control.

    • ''%{^HOOK}'' API introduced - this hash contains coderefs which are called when various perl keywords which are hard or impossible to wrap are called. The keys of this hash are named after the keyword that is being hooked, followed by two underbars and then a phase term; either "before" or "after".

    • New environment variable ''PERL_RAND_SEED'' which can be used to cause a perl program which uses ''rand'' without using ''srand()'' explicitly or which uses ''srand()'' with no arguments to be repeatable.

    • Defined-or and logical-or assignment default expressions in signatures

    • @INC Hook Enhancements and $INC and INCDIR

    • Forbidden control flow out of ''defer'' or ''finally'' now detected at compile-time

    • Optimistic eval in patterns - the use of ''(?{ …​ })'' and ''(??{ …​ })'' in a pattern disables various optimisations globally in that pattern. This may or may not be desired by the programmer. This release adds the ''(*{ …​ })'' equivalent. The only difference is that it does not and will never disable any optimisations in the regex engine.

    • REG_INF has been raised from 65,536 to 2,147,483,647

    • New API functions ''optimize_optree'' and ''finalize_optree'' for operating on optree fragments

    • Some ''goto''s are now permitted in ''defer'' and ''finally'' blocks

    • New regexp variable ''${^LAST_SUCCESSFUL_PATTERN}'' - this allows access to the last successful pattern that matched in the current scope

    • Locale category ''LC_NAME'' now supported on participating platforms

  • Incompatible Changes

    • ''readline()'' no longer clears the stream error and eof flags

    • ''INIT'' blocks no longer run after an ''exit()'' in ''BEGIN''

    • Syntax errors will no longer produce "phantom error messages".

    • ''utf8::upgrade()'' - starting in this release, if the input string is ''undef'', it remains ''undef''

  • Deprecations

    • Use of '' ' '' as a package name separator is deprecated, will be removed in Perl 5.42

    • ''switch'' and smartmatch operator ''~~'' is deprecated, will be removed in Perl 5.42

  • Internal Changes

  • Lots of modules were updated

  • Changes in [https://metacpan.org/release/RJBS/perl-5.38.0-RC2/view/pod/perldelta.pod#Diagnostics Diagnostics] can cause failures in tests

ToolbxReleaseBlocker

Up to date [https://src.fedoraproject.org/container/fedora-toolbox fedora-toolbox] [https://opencontainers.org/ OCI] images must be published on [https://registry.fedoraproject.org/ registry.fedoraproject.org] as release-blocking deliverables, and there must be release-blocking test criteria to ensure usable [https://src.fedoraproject.org/rpms/toolbox toolbox] RPMs.
