Knowledge Base LTS Windows and Security Deadlines FAQ

Running a community knowledge base alongside an active discussion board requires systematic attention to software maintenance schedules. Community administrators often rely on wiki platforms to host FAQs, documentation, and user guides. In late October 2026, understanding when maintenance windows close is vital for keeping server infrastructure secure and planning timely platform upgrades.

Which MediaWiki LTS releases are currently supported?

As documented in the endoflife.date MediaWiki release data, the active Long-Term Support release is cycle 1.43. MediaWiki 1.43 was launched on 2024-12-21 and carries an end-of-life deadline of 2027-12-31. This multi-year maintenance window gives community teams ample runway to stabilize extensions, review themes, and strengthen forum admin security without undergoing disruptive yearly migrations.

The latest point update for this branch is version 1.43.11, which was published on 2026-10-02. In contrast, the preceding LTS cycle, MediaWiki 1.39, was released on 2022-11-30 and officially reached its end-of-life date on 2025-12-31, concluding with version 1.39.17 released on 2025-12-16. Community knowledge bases that remain on cycle 1.39 no longer receive upstream maintenance fixes.

What are the support deadlines for standard short-term releases?

Non-LTS branches operate on much tighter support cycles. Administrators managing knowledge bases on these intermediate branches must track upcoming cutoff dates closely:

Communities running cycle 1.45 must plan their next update immediately, as support ceases at the end of December 2026.

Which historical branches have already reached end-of-life?

Reviewing historical lifecycles helps administrators audit neglected subdomains or unmaintained legacy knowledge bases. According to endoflife.date's MediaWiki lifecycle tracker, numerous previous cycles are fully deprecated:

How do maintenance patterns differ between LTS and non-LTS releases?

Standard releases are supported for approximately one year, while LTS editions provide multi-year coverage. For instance, standard release 1.44 spanned from 2025-07-02 to 2026-07-31, whereas LTS release 1.43 spans from 2024-12-21 until 2027-12-31. Despite differing lifespans, upstream maintainers regularly coordinate security rollouts across supported branches. On 2026-10-02, synchronized point updates were issued simultaneously for 1.43.11, 1.45.6, and 1.46.2. Following structured CISA software patching principles helps administrators deploy these point releases promptly without falling behind.

What maintenance schedule should administrators follow?

To avoid operating unsupported knowledge base software, community maintainers should establish a recurring upgrade workflow:

  1. Verify your current installation branch against active lifecycle calendars to confirm it has not passed its support cutoff.
  2. Apply intermediate patch releases promptly, such as the maintenance updates deployed on 2026-10-02 across supported series.
  3. If hosting on cycle 1.45, begin migration plans toward LTS cycle 1.43 or branch 1.46 before the 2026-12-31 deadline arrives.
