LTS Releases and Support Policy
Legato is moving to a Long Term Support (LTS) Release model where each LTS release is supported for 2 years (24 months) from the initial stable release date. LTS releases will get security and bug fix updates minimum twice a year.
During the support period new features may be added at our discretion depending on whether
- They are needed to meet specific regulatory or MNO requirements or cellular standards for new products.
- If they carry a low risk of introducing regressions.
Pre-release versions (beta release, release candidates or development versions) are not covered by any support period. Sometimes a particular feature may be marked as "experimental" or "preview" in a release. These are also not covered by the support period.
It is recommended that customers move to the latest LTS release and regularly update to newer releases before the support period ends. Our policy is to not continue fixing bugs in releases that are beyond the support period.
Example:
Legato 19.11.0 was released in January 2020 and will be supported through January 2022.
Legato 21.05.x is estimated to be released by end of Nov. 2021 and is estimated to be supported through Nov. 2023.
