Q&A
- How does the backport work? Ans: We recommend to backport one version back only if there is a critical bug.
- Is there something like LTS in PX4 as there are for Ubuntu for example? Ans: Based on the large regressions, it is not recommended to do backports or make changes more than a version back. There are plans to bring an LTS release cycle maybe a long time from now which needs proper support and funding and dedicated people as LTS mangers.
