+# BREAKING CHANGES
+
+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
 
-Another issue with the new LaTeX hook mechanism surfaced in the external
-library which is being worked around now.
+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.
