Current status

• Targeted release: Fedora Linux 38
• Last updated: 2023-01-23

• FESCo issue: #2935
• Tracker bug: #2163527
• Release notes tracker: #958

Detailed Description

The goal is to update Fedora to the latest available version of TeXLive (2022), including its large number of associated components.

This will resolve outstanding bugs in the existing TeXLive (2021) packages, add new features, improve performance, and expand internationalization support.

Benefit to Fedora

Updating to TeXLive 2022 brings the latest versions of the TeX engines and components into Fedora, which improves document rendering and conversion. A number of Fedora packages include TeX support, which depend on the TeXLive utilities.

In each TeXLive release, a large (hundreds) number of TeX components are updated, a significant (~100) number of new TeX components are added, and core functionality is enhanced and optimized.

Documents should render properly and export into various formats without issues.

Scope

• Proposal owners:

The necessary changes are contained to the texlive and texlive-base packages. These changes have already landed in rawhide.

• Other developers:

No changes should be necessary for other packagers/developers.

• Release engineering: #Releng issue number

• Policies and guidelines: N/A (not needed for this Change)

• Trademark approval: N/A (not needed for this Change)

• Alignment with Objectives:

It does not align with any current Objectives.

Upgrade/compatibility impact

Users will need to delete old TexLive 2021 cache in order to properly use TeXLive 2022 upon an upgrade. To do this, a user simply (and carefully) needs to run:

rm -rf ~/.texlive2021

A new ~/.texlive2022 directory will be generated and used when the user invokes TeXLive related functionality, but TeXLive will attempt to use the older cache directory and it will not work properly.

How To Test

Packagers who have packages that use TeX to generate documentation should simply attempt to rebuild their package in rawhide with the TeXLive 2022 packages. If it succeeds and the documents generated are correct, nothing further is necessary. If it fails or the documents generated are corrupted/damaged, please open a bug against the texlive component.

User Experience

The way that the user interacts with TeX/TeXLive does not change in this release. A very small number of components (~10) in TeXLive have been obsoleted and removed, but they have either been silently replaced by other functionality or they were outdated documentation.

Dependencies

While other packages in Fedora do depend on texlive component packages, this is almost always for build-time generation of documentation, and not in a traditional "linking to library" approach.

Packages with tex() or texlive dependencies should not need to make any changes to use TeXLive 2022.

Contingency Plan

• Contingency mechanism: Roll back to latest texlive/texlive-base 2021 packages.
• Contingency deadline: N/A (not a System Wide Change)
• Blocks release? N/A

Release Notes

Fedora 38 has updated its TeXLive support to 2022. Users who upgrade from older versions of Fedora and who have used TeXLive previously may need to delete the ~/.texlive2021 cache directory in order to have a working TeXLive environment. A new ~/.texlive2022 cache directory will be generated on first use of TeXLive 2022, but TeX will attempt to use older cache directories if they exist.
