Esp-idf 3.0.5 > 3.1 ????

[Grandpa]

Pardon the 'noob question' here but I really don't understand why Espressif came out with idf version 3.0.5 AFTER releasing version 3.1 ???

I mean usually the latest development are done on the highest release number, which is 3.1 in this case, making it also the latest version but it seems that v3.0 is constantly updated even after the release of v3.1

Thanks

Critical bugfixes are backported to older versions but new features are not.

As WiFive said, we backport bug fixes to earlier versions.

Although we are in the unusual situation right now where some bugs have been fixed in v3.0.5 which are not fixed in v3.1. They are fixed if you check out a prerelease from the release/v3.1 "release branch". A 3.1.1 release is in final testing now and will be released ASAP.
