hi. i can't date it exactly, but in the last week or so, editing a source buffer (with =C-c '=) adds spaces (to the "tab location") of previously blank lines.
See https://lists.gnu.org/archive/html/emacs-orgmode/2021-05/msg00867.html The goal of the change was to fix some (electric) indentation issues when editing a src block directly.As I write in the linked thread, setting `org-src--preserve-indentation' should
revert this behaviour. Regards, -- Sébastien Miquel
