I use spacemacs only for an org-mode todo file. I recently re-installed spacemacs and emacs and noticed a behavior change.
Let's say I have a file like:
* TODO Header - List item 1 - List item 2
In inline mode, if I do Alt+Ret,Ret it used to be context specific. If I was on a header, then it would insert a new header at the same level; if I was on a list item line then it would insert a new list item. Now, no matter what line I am on it inserts a new header.
