This is a proposed Change for Fedora Linux.
This document represents a proposed Change. As part of the Changes process, proposals are publicly announced in order to receive community feedback. This proposal will only be implemented if approved by the Fedora Engineering Steering Committee.

Summary

Update Zlib-ng on Fedora 42 to version 2.2.x. Currently, Fedora distributes Zlib-ng 2.1.7.

Current status

  • Targeted release: Fedora Linux 42
  • Last updated: 2024-09-24

Detailed Description

Update zlib-ng to the latest version from branch 2.2.x. Currently, that's version 2.2.2, but it could change until the release considering that updates on the same branch are expected to be API/ABI stable.

Feedback

Benefit to Fedora

Major version 2.2.x provides new optimizations, rewrites deflate memory allocation and improves the buildsystem and tests.

More details are available in the following pages:


Scope

  • Policies and guidelines: N/A (not needed for this Change)
  • Trademark approval: N/A (not needed for this Change)
  • Alignment with the Fedora Strategy:

Upgrade/compatibility impact
