Bamboo 10.0 dies Thursday, Jira 10.0 dies Friday —
the same clock, one day apart.
Bamboo 10.0 reaches end of life on August 21, 2026. Jira Software 10.0 follows on August 22. Two products, one day apart, and most Atlassian Data Center shops run both — Bamboo builds what Jira tracks. The pairing is not a coincidence: both shipped their 10.0 releases on consecutive days in August 2024, and Atlassian’s support policy retires every Data Center release exactly two years after it was released. Consecutive release days become consecutive death days.
This is the third piece of a set. We covered Confluence and Bitbucket 9.1 under the same rule this week; this one closes out the Data Center family, and the advice converges on the same point for all four products.
The rule that produces the pairing
Atlassian’s end-of-life policy: the company “supports releases for two years after the initial feature or Long-Term Support (LTS) release.” No tiers, no extension, and — the part that matters here — no distinction in duration between a feature release and an LTS. Both get two years. What LTS buys is backports for the whole window; a feature release is superseded within weeks and only its date lingers.
Bamboo 10.0 shipped August 21, 2024; Jira Software 10.0 shipped August 22, 2024. Add two years. That is the entire explanation, and it is why every August since will look similar: the Data Center products release in loose synchrony, so they retire in loose synchrony too.
Every date, both products
| Product | Version | Type | Released | End of life | Risk score |
|---|---|---|---|---|---|
| Bamboo | 12.1 | LTS | 2025-12-16 | 2027-12-17 | 10 |
| Bamboo | 10.2 | LTS | 2024-12-19 | 2026-12-20 | 18 |
| Bamboo | 10.0 | feature | 2024-08-21 | 2026-08-21 | 25 |
| Jira Software | 11.3 | LTS | 2025-12-03 | 2027-12-03 | 10 |
| Jira Software | 10.3 | LTS | 2024-12-05 | 2026-12-05 | 18 |
| Jira Software | 10.0 | feature | 2024-08-22 | 2026-08-22 | 25 |
The feature releases in between (Bamboo 10.1, 11.0, 12.0; Jira 10.1–10.7, 11.0–11.2) follow the identical two-year rule; every one is on the Bamboo and Jira Software lifecycle pages.
The four-month LTS trap
The natural instinct on losing 10.0 is to move to “the LTS” — Bamboo 10.2 or Jira 10.3. Both are still supported. Both also end in December: Bamboo 10.2 on December 20, 2026, Jira 10.3 on December 5, 2026. Landing there buys four months and then requires the exercise again, over the holidays. It is the same trap we flagged for Bitbucket 9.4 LTS — the LTS label tells you a line gets backports, not that it has runway left.
The releases with a year of runway are the next LTS on each product: Bamboo 12.1 (to December 17, 2027) and Jira Software 11.3 (to December 3, 2027). Two upgrades in four months versus one upgrade now: the arithmetic favours skipping the near LTS entirely.
Where to land
If you are on Bamboo 10.0 or 10.1: go to 12.1 LTS. It is a two-major hop, but 10.x → 12.x is the path Atlassian documents, and 12.1’s window runs to December 2027.
If you are on Jira Software 10.0–10.2: go to 11.3 LTS. Same reasoning; the 10.3 LTS is only worth it if something pins you to the 10.x line, and then only as a staging point.
If you run both, plan them together. The retirements landed one day apart because the releases did; the upgrades can be sequenced in one change window rather than two. Bamboo first is usually the lower-risk order — a build server has fewer plugin dependencies than a Jira instance — and it validates the environment before the Jira change.
If you are on 9.x of either: Jira 9.12 LTS died November 29, 2025; every Bamboo 9.x is gone. You are past overdue, and unlike Confluence and Bitbucket neither product carries a CISA KEV entry — which is a fact about the catalog, not a reason to wait. Our Atlassian Server and Data Center guide covers the broader transition.

Frequently Asked Questions
When do Bamboo 10.0 and Jira Software 10.0 reach end of life?
Bamboo 10.0 reaches end of life on August 21, 2026 and Jira Software 10.0 on August 22, 2026 — two years to the day after each was released (August 21 and 22, 2024), under Atlassian's policy of supporting every Data Center release for two years after its initial release.
Are Bamboo 10.0 and Jira 10.0 LTS releases?
No. Both are feature releases. The LTS lines are Bamboo 10.2 (end of life December 20, 2026) and 12.1 (December 17, 2027), and Jira Software 10.3 (December 5, 2026) and 11.3 (December 3, 2027). Feature releases and LTS releases get the same two-year window; the difference is that LTS lines receive bug-fix and security backports for their whole window.
Which version should I upgrade Bamboo and Jira to?
Bamboo 12.1 LTS (to December 17, 2027) and Jira Software 11.3 LTS (to December 3, 2027). The nearer LTS lines — Bamboo 10.2 and Jira 10.3 — are still supported but end in December 2026, four months from the 10.0 retirements, so landing there schedules a second upgrade almost immediately.
How long does Atlassian support Data Center releases?
Two years after the initial feature or LTS release, per Atlassian's end-of-life policy. There is no extended-support tier. The same rule governs Confluence, Bitbucket, Jira and Bamboo, which is why their retirement dates cluster — a version of something in the Data Center family retires most months.
