For example, in 12.0.9:

12 is the major version,

0 is the minor version,

9 is the build number.

An increase in just the build number means a maintenance release – an update that only contains bug fixes.

An increase in the minor or major version number means a feature release. A feature release contains new and updated features. Since feature releases will be quite frequent, there will be fewer maintenance releases between them.

An increase in the major version number also means that some things won't be compatible with earlier versions.

Client and server, translation

For the purposes of translation, we guarantee compatibility for one major version “ahead” and “behind”: anyone using memoQ translator pro 11.x must be able to translate projects on memoQ server 10.x or memoQ TMS 12.x. Similarly, memoQ translator pro 12.x works with memoQ TMS 11.x and will work with memoQ TMS 13.x.

Client and server, project management

Major version must be the same between memoQ TMS and memoQ project manager edition. That means you can use any 11.x version of memoQ project manager to manage projects on any 11.x version of memoQ TMS, but need a 12.x version of memoQ project manager to manage projects on any 12.x version of memoQ TMS.

Projects and resources

Internal project and resource formats won't change “inside” a major version. For example, if memoQ Ltd. intends to introduce a new feature that requires a change in the term base format, we won't introduce it before major version 13. When version 13 comes out, the memoQ and memoQ TMS installers might migrate some resources to the new format, or a project might be migrated to the new format when you first open it.

Since memoQ introduces about 5 feature releases in a year, it would be problematical to install all of them side by side. To avoid this, memoQ 12.1 overwrites memoQ 12.0 by default, and 12.2 overwrites any of those. However, memoQ 12.x installs side-by-side with the previous major version, memoQ 11.x. All of the above is just the default behavior: the user can always choose to install memoQ 12.1 or a later minor version to a different folder.

What do we mean by "supported memoQ versions"?

• Our support team deals exclusively with issues reported on supported memoQ versions.
• Our services team only maintains supported memoQ versions on memoQ TMS private cloud instances.
• memoQ TMS cloud instances are always on the latest version, so they're always supported.
• Our development team only provides bug fixes (that is, maintenance releases) for supported versions.

If you don’t require any of the above, you can continue running unsupported memoQ versions.

Supported versions

With the release of 9.0, we introduced a new concept: long-term support (LTS) versions. It means that every year, at a predictable, scheduled time, we will produce a feature release that will be supported for 15 months. The first such version was 9.0.

Version support follows these rules:

• LTS versions are released each year, and are supported for 15 months.

  The current LTS version is 11.2 (released in 2025), supported until about Q4 2026 (3 months after the next LTS version is released).

  The next LTS version will be 12.3, expected in Q2 2026, and supported until late 2027.

• The latest minor version is always supported.

This means that beginning with 9.0, customers have two choices:

• Those who want to get the new features quickly, and don't mind upgrading every 3 months, can always use the latest memoQ version.
• Those who see stability more important than new features, or can't upgrade every 3 months, can always use the LTS version. To stay on a supported version, they need to upgrade once a year. This gives them time to prepare for the upgrade, and 3 months to carry it out, after a new LTS version is released.

To get a license for any major or minor version, users need to have a valid SMA on the date when that version comes out.

Due to the frequent release cycles, several bug fixes will only get into the next minor version (feature release). This means that if your SMA expires, and your version is no longer supported, you won't receive bug fixes to your latest version anymore.

Release schedule

Want to plan ahead with memoQ? Check out the release agenda below to see the upcoming releases:

• 12.3 (LTS): Q2 2026

• 12.4: Q3 2026

• 12.5: Q4 2026

As of its nature, memoQ TMS cloud has a slightly different concept. If you're a memoQ TMS cloud user, you always get the latest maintenance version of memoQ. The updates typically come in 14 days after the latest release is officially announced by memoQ Ltd.

Compatibility

Compatibility rules for memoQ TMS cloud are the same as for the other memoQ products.

SMA and eligibility for new version

memoQ TMS cloud subscription includes SMA, so users with a valid subscription are always eligible for using both memoQ support and the latest version of memoQ.
