-# BREAKING CHANGES
+Hotfix for handling of TeX conditionals on a path.  We can't forward \relax and
+frozen \relax through the parser because there is existing code that relies on
+this.
 
-If a topath is bent by any of the in=, out=, bend=, etc. options, a Bezier
-curve is constructed in the background.  To infer the positions of the control
-points the start and end coordinate are converted to absolute coordinates.
-However, this has the effect that subsequent points on the path think that the
-endpoint of the topath was absolute which can lead to counter-intuitive path
-construction, e.g.
-```latex
-\draw (2,0) to[out=0,in=180] +(1,0) -- ++(0,-1) -- +(1,0);
-```
-If old code relies on this behavior, this drawing will silently break!  Please
-open an issue if you rely on this.

-# Bug fixes
-
-This release introduces a fix for path handling which concerns expansion of
-tokens on the path in particular with respect to conditional.  Previously when
-the expansion of a conditonal resulted in a frozen \relax the parser would just
-give up.  Now the parser will skip over the frozen \relax and continue to
-expand tokens.  Whether this will result in a meaningful expansion is up to the
-user.
-
-This release also includes other bug fixes. On GitHub you can click the commit
-hashes and the issue numbers to get to the fix and the ticket, respectively.
