Discourse Container Lifecycles: Upgrade Schedules and Key Numbers
Self-hosting community discussion software with Docker containers requires administrators to navigate regular software rollouts and end-of-life dates. In late October 2026, forum owners evaluating their container maintenance schedules must balance monthly release branches against designated Long Term Support baselines. According to the Discourse endoflife.date API data, the software follows a structured calendar release progression that defines exact maintenance deadlines for every standalone container deployment.
Cycle 2026.9: Active Standard Deployment Milestones
The active production release in the standard development branch is cycle 2026.9. Official records define the specific release boundaries for administrators managing current production containers:
- Initial release date: 2026-09-22
- End-of-life cutoff: 2026-11-24
- Latest point release: 2026.9.1
- Long Term Support status: false
Because standard cycles do not carry Long Term Support status, administrators tracking this branch must prepare for rapid maintenance intervals. Before applying monthly rebuilds to production environments, forum owners can review server requirements and networking configurations in our guide to Discourse container architecture, ports, mail, and diagnostics.
Cycle 2026.7: The Designated Long Term Support Baseline
For community administrators who prioritize operational stability over rapid feature shifts, Discourse designates select versions for extended maintenance. The primary long-term reference point in 2026 is cycle 2026.7. The lifecycle figures documented in the Discourse endoflife.date API data highlight its maintenance status:
- Initial release date: 2026-07-28
- Long Term Support status: true
- Latest point release: 2026.7.4
Choosing an LTS branch reduces the frequency of mandatory rebuilds while preserving access to critical stability patches. For a broader perspective on selecting discussion software for your community, consult our Discourse forum platform profile.
Cycle 2026.1: Retired 2026 Long Term Support Data
Cycle 2026.1 provided the primary Long Term Support base earlier in the year. Its lifecycle tracking milestones show the complete support timeline for that branch:
- Initial release date: 2026-01-28
- End-of-life cutoff: 2026-09-22
- Latest point release: 2026.1.9
- Long Term Support status: true
The retirement of cycle 2026.1 on 2026-09-22 coincided with the debut of cycle 2026.9. Containers operating on cycle 2026.1 are past official project support, signaling that administrators must migrate their setups to a supported release.
Cycles 2026.2 Through 2026.6: Standard Monthly Progression
The standard releases published across early and mid-2026 illustrate the monthly schedule used for non-LTS releases. Each release reaches its end of life as newer cycles arrive:
- Cycle 2026.6: released 2026-06-30, reached end of life on 2026-08-25, latest build 2026.6.3 (released 2026-08-25).
- Cycle 2026.5: released 2026-05-28, reached end of life on 2026-07-28, latest build 2026.5.2 (released 2026-07-28).
- Cycle 2026.4: released 2026-04-28, reached end of life on 2026-06-30, latest build 2026.4.2 (released 2026-06-30).
- Cycle 2026.3: released 2026-03-31, reached end of life on 2026-05-28, latest build 2026.3.1 (released 2026-05-18).
- Cycle 2026.2: released 2026-02-26, reached end of life on 2026-04-28, latest build 2026.2.2 (released 2026-03-31).
All versions in this group carry a non-LTS status. Because standard cycles expire promptly as subsequent versions launch, forum owners running monthly branches must rebuild their containers frequently to maintain upstream support.
Cycles 3.4, 3.5, and the 2025 Transition Milestones
The lifecycle data records the evolution from legacy semantic numbering to calendar-based versioning. Key milestones from that period include:
- Cycle 3.4: marked as LTS (true), released 2025-02-04, reached end of life on 2025-08-19, latest build 3.4.7 (released 2025-07-29).
- Cycle 3.5: marked as LTS (true), released 2025-08-19, reached end of life on 2026-01-28, latest build 3.5.4 (released 2026-01-28).
- Cycle 2025.11: marked as non-LTS (false), released 2025-11-25, reached end of life on 2026-01-28, latest build 2025.11.2 (released 2026-01-28).
- Cycle 2025.12: marked as non-LTS (false), released 2025-12-30, reached end of life on 2026-02-26, latest build 2025.12.2 (released 2026-02-26).
By reviewing these historical cutoff points alongside active releases, forum administrators can structure predictable maintenance intervals that keep community containers stable and secure.
