Hi Team Are there any plans to back port bug fixes to older releases as well?

Usually we will fix forward, unless it is an important vulnerability fix, e.g. 1.5.1

Any plans to port bug fixes in existing releases as well going forward?

No official release unless raised as a significant issue. but it’s easy to create bug fix branches and release docker images.

Would it be possible to maintain last and current release version? Considering Pinot has matured a lot over the years, maintenance overhead shouldn't be too much with fewer new bugs but it would still give an option for users to adopt bug fix without version upgrade.

Typically OSS community won't maintain bugfix version unless it's broadly impacted. Users should cherry-pick and manage for themselves, Or you can find some vendor which provide this service
