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.

@fweimer, I've prepared a release note for the glibc update in F31. Could you please review it?

== glibc has been updated to 2.30

The GNU C Library (`glibc`) has been updated to version 2.30. This version provides:

* 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=HEAD[].

Thanks!

@mareksu I would list the following features:

Unicode 12.1.0 support for character encoding, character type information, and transliteration.
New functions twalk_r, getdents64, gettid, tgkill, pthread_cond_clockwait, pthread_mutex_clocklock, pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock, sem_clockwait.

I'm not sure if we should go into detail about potential backwards compatibility issues.

The link should go to https://sourceware.org/git/?p=glibc.git;a=blob;f=NEWS;hb=release/2.30/master.

Thanks, @fweimer, I've fixed the link and added the features.

Here's the current pull request with my release notes for reference: https://pagure.io/fedora-docs/release-notes/pull-request/405

Regarding the backwards compatibility, I'll leave that up to you. If you decide that it should be mentioned in the release notes, let me know as soon as possible because the release is near.
