+## Fixes for amsmath (luatex)
 
+[Work in progress. Skips below are sometimes too large with the version
+currently available. To be improved.]
 
+There are new fixes which will make amsmath useable in the most typical
+cases, with labels at the right and at the left; `align` (but not
+`align*`), `multline(*)`, `aligned`, `gather` `subequation`, `equation`.
 
+The commands `\text` and `\intertext` has been patched to set the
+correct direction (but `\hbox` won’t work as expected).

+Fixing `equation` turned out to be much more involved as expected
+before the long-standing bugs in `\eqno` and `\leqno`. Not only the the
+label may be misplaced with the latter (sometimes), but the
+computations for the skip before the equation are reversed (the skip
+for `\eqno` is that for `\leqno` and vice versa). So, a dirty trick has
+been added to overcome this bug.
