github - How to temporarly go back to previous versions of your code but preserve the latest changes in Git -

i have git repository 2 tags, named version-1 , version-2. i'm working on version-3 of app, code has changed lot since version-2 , still have lot of work release version-3 there changes/fixes version-2 , wondering if possible go tag version-2 make changes (bug fixes) , come left.

is possible go tag version-2 make changes (bug fixes) create new tag version-2.1 release changes , come left? if yes, process?

thanks

easiest create branch tag:

git checkout version-2 -b branchname 

to resume working on new release, check out master branch again:

git checkout master
