• fix: the debug-mode deprecation warning for a language code without a region no longer says that v27 replaces aliases. 26.7.0 and 26.7.1 warned that v27 turns 'iw' into 'he' or 'tl' into 'fil' and asked you to rename them. v27 only gives such codes their canonical casing ('EN' becomes 'en', 'IW' becomes 'iw'), so iw, tl, eng and similar codes stay as they are. If you renamed them because of that warning, you can keep or restore the old codes. The warning now only appears when the casing changes.
