This issue tracks the release note for the following Fedora Change:

https://bugzilla.redhat.com/show_bug.cgi?id=1782545

If you own this change, please add additional information here that we should communicate to Fedora users. Specifically, please consider:

New features available because of this change - pick 2 or 3 that are important
Considerations for users of previous releases of Fedora (upgrade issues, format changes, etc.)
Links to any upstream Release Notes
If this helps Fedora be a superior environment for our target audiences, please explain how so that we can emphasize this.

Your notes to us do not need to be formally written. We will edit them and add details as needed. This is a way for you to ensure that we know what is critical about your change.

If you want to write this release note, then:

Assign this issue to yourself
Check the wiki page linked above, find out what the change is about
Determine whether the change actually made it into the release or not[0]
Write a draft release note using that information against the correct branch here, in Pagure. (or see below)
Get in touch with the contact person/people listed on the wiki page, either through IRC or e-mail, and ask them to check your draft for technical accuracy
Submit your Release Note as a PR to this repository.

Once you're done with the above, make sure to either commit the relnote to an appropriate section of the Release Notes book, or, if you're not familiar with Git, AsciiDoc, or whatever else, just add it to this issue as a comment and let pbokoc[1] know that you're done with this one and you'd like the note included. Be sure to do this at least one day before the final release (October 29 according to the current schedule). Also make sure to do this even for relnotes that haven't been checked by the change owner.

[0] You can do that by asking the change owner listed on the wiki page; alternatively you can infer it by checking the tracker bug (linked in Wiki) in Bugzilla and looking at its status; see bug comments for details. Ask someone on the mailing list or on IRC if you're not sure.
[1] In #fedora-docs on FreeNode (UTC+1 timezone, online mostly during the day on weekdays), or pbokoc @redhat.com if you can't get a hold of me on IRC.

Hi @ashankar,

does this issue need to be described in f32? Is it ready for a description?

Thanks

submachine commented 2 years ago

I expect that it does indeed need to be described. The description should go under the Development -> C section. I have written a draft, using https://pagure.io/fedora-docs/release-notes/blob/f31/f/modules/release-notes/pages/developers/Development_C.adoc as for formatting guidance.

== glibc has been updated to 2.31

The GNU C Library (`glibc`) has been updated to version 2.31. This version provides:

* Partial support for features from the draft ISO C2X standard (via the _ISOC2X_SOURCE feature test macro).
* New C function, `pthread_clockjoin_np`
* Security fixes
* Bug fixes
* Improved performance
* Improved compliance with the Portable Operating System Interface (POSIX) standard
* New localizations

For the complete list of changes, see the `glibc` release notes: link:https://sourceware.org/git/?p=glibc.git;a=blob;f=NEWS;hb=release/2.31/master[].

@codonell @fweimer, does this look okay to you?

codonell commented 2 years ago

Looks good to me. I would list CVE-2019-19126 as fixed in the "Security fixes". I would list "nmw_MM" as the new locale. Use POSIX directly instead of the full name. Add an entry for "* The DNS stub resolver will send the DNSSEC AD (authenticated data) bit if the trust-ad option is set via the options directive in /etc/resolv.conf (or if RES_TRUSTAD is set in _res.options). In this mode the AD bit is available to applications."

@pbokoc, someone already described this in /developers/Development_C.adoc probably as a part of some other issue. There is already everything @codonell mentioned in his previous comment.
