What "LTS" Actually Means

LTS stands for Long-Term Support. It is a term borrowed from the wider software world, and in Moodle it means something precise: certain releases are officially designated as Long-Term Support releases and are kept maintained for much longer than the rest.

When people say a Moodle version is "the LTS", they mean it is the release an organisation is expected to standardise on if it wants stability and a predictable support window: install it once, stay on it, and receive fixes for years instead of months. It is the version you build policies, integrations and training around, rather than chasing the latest one every six months.

That is the whole idea, but the useful details are in the numbers: which releases get how much support, and what that changes for you.

How Moodle's Release Cycle Works

Moodle follows a fixed calendar, which is what makes an LTS meaningful in the first place:

  • Major releases arrive twice a year, in April and October. These are the "version" releases (5.1, 5.2, 5.3 and so on) that bring features, not just fixes.
  • Minor (point) releases land roughly every two months (February, April, June, August, October, December) and contain bug fixes and security patches for the versions already supported.

Every major release is then supported for a defined period, and this is where the standard-versus-LTS distinction sits:

Release typeGeneral (bug-fix) supportSecurity support
Standard release12 months18 months
Long-Term Support (LTS)12 months36 months

Read it carefully, because the difference surprises people: general bug-fix support is 12 months for both types. What an LTS actually buys you is the security window: 36 months instead of 18. For an institution that treats patches as a compliance matter, doubling the security-support horizon from a year and a half to three years is the entire point.

Moodle designates a new LTS roughly every two years. Past LTS releases include 1.9, 2.7, 3.5, 3.9, 4.1 and 4.5. The next one follows the established October cadence.

Standard Release vs LTS: The Trade-off

Neither option is better in the abstract; they optimise for different things.

  • A standard release gives you features sooner. Because a standard release only lives 18 months for security, you upgrade more often, but every upgrade brings the newest functionality: new AI providers, new activity and grading tools, refreshed interfaces. If your organisation wants to be near the front of Moodle's roadmap, this is the path.
  • An LTS gives you stability and a longer horizon. You inherit a large, consolidated batch of features when you move to it, and then you stop: the platform stays patched for three years on security. You trade "always newest" for "predictable and low-churn".

A useful way to think about it: you are not choosing between a better and a worse Moodle. You are choosing between more frequent change and fewer, bigger, better-planned migrations.

What an LTS Gives You in Practice

Choosing an LTS is not just about dates on a support table. It changes how you run the platform day to day.

  • A stable target for plugins and themes. A three-year security horizon means your plugin and theme ecosystem has a stable core to build against, instead of re-testing customisations against a new major version every six months.
  • Lower operational churn. Every major upgrade carries risk: the larger the batch of changes, the more testing it needs. Fewer upgrades means fewer risky windows.
  • Simpler budget and planning. An LTS makes recurring work plannable: you know roughly when the next migration is, so you can schedule it, budget it and communicate it.
  • Easier compliance conversations. "This platform receives security patches until year X" is a sentence auditors and IT policies understand. An LTS puts a concrete date behind your security posture.

When to Choose an LTS (and When Not To)

An LTS is usually the right choice when:

  • You run a large or institutional LMS where unscheduled change is expensive.
  • You have custom themes, plugins or integrations that are costly to re-test.
  • You have limited maintenance capacity and need predictability.
  • Compliance, auditability or a defined security window is a hard requirement.
  • You would rather migrate less often and in a planned way.

A standard release can be the better fit when:

  • Access to the newest features is a priority (for example, adopting new AI capabilities early).
  • You have the team and process to upgrade on a six-to-eighteen-month rhythm.
  • Your platform is small, or your course delivery does not depend on long-term stability.

Many organisations land on a hybrid: run a standard release on a staging or pilot site to evaluate what is coming, while the production platform tracks the LTS.

How LTS Releases Shape Your Upgrade Planning

Understanding LTS changes your upgrade strategy in a concrete way:

  • You can skip intermediate versions and land on the LTS. Because an LTS consolidates everything that shipped in the standard releases before it, moving from one LTS to the next is a legitimate, supported path. You do not have to adopt every six-month release along the way.
  • Cross-version jumps have rules. Moodle only supports upgrading from certain older versions, so an old site may need one or more intermediate steps before it can reach the LTS. Planning around the LTS cadence is the moment to sort that out.
  • Support ending is the deadline that matters. With a standard release, that deadline arrives fast: security support runs out 18 months after release, and once it does, the version stops receiving fixes while you are still running it. Moving to the current LTS is how you reset that clock.

Key Takeaways

  • LTS = Long-Term Support. A designated Moodle release maintained far longer than a standard one.
  • The difference is the security window: 18 months for a standard release, 36 months for an LTS. General bug-fix support is 12 months for both.
  • Major releases ship in April and October, and a new LTS is designated roughly every two years.
  • Standard releases give you features sooner; an LTS gives you stability and a longer support horizon. Choose based on how much change you can absorb and how long a security window you need.
  • Upgrade planning should follow the LTS cycle, not the six-month release cadence.
