+There are a few things that the convert-ly cannot handle. Here's a list of limitations
+that the community has complained about.
+
+This bug report structure has been chosen because convert-ly has a structure that doesn't
+allow to smoothly implement all needed changes. Thus this is just a wishlist, placed
+here for reference.
+
+1.6->2.0:
+ Doesn't always convert figured bass correctly, specifically things like {< >}. Mats' comment on working around this:
+   To be able to run convert-ly
+   on it, I first replaced all occurencies of '{<' to some dummy like '{#'
+   and similarly I replaced '>}' with '&}'. After the conversion, I could
+   then change back from '{ #' to '{ <' and from '& }' to '> }'.
+ Doesn't convert all text markup correctly. In the old markup syntax,
+ it was possible to group a number of markup commands together within parentheses, e.g.
+   -#'((bold italic) "string")
+   This will incorrectly be converted into
+   -\markup{{\bold italic} "string"}
+   instead of the correct
+   -\markup{\bold \italic "string"}
+2.0->2.2:
+ Doesn't handle \partcombine
+ Doesn't do \addlyrics => \lyricsto, this breaks some scores with multiple stanzas.
+2.0->2.4:
+ \magnify isn't changed to \fontsize.
+    - \magnify #m => \fontsize #f, where f = 6ln(m)/ln(2)
+ remove-tag isn't changed.
+    - \applymusic #(remove-tag '. . .) => \keepWithTag #'. . .
+ firstpagenumber isn't changed.
+    - firstpagenumber no => printfirstpagenumber = ##f
+ Line breaks in header strings aren't converted.
+    - \\\\  as line break in \header strings => \markup \center-align <
+      "First Line" "Second Line" >
+ Crescendo and decrescendo terminators aren't converted.
+    - \rced => \!
+    - \rc => \!
+2.2->2.4:
+ \turnOff (used in \set Staff.VoltaBracket = \turnOff) is not properly converted.
+2.4.2->2.5.9
+ \markup{ \center-align <{ ... }> } should be converted to:
+ \markup{ \center-align {\line { ... }} }
+ but now, \line is missing.
+2.4->2.6
+ Special LaTeX characters such as $~$ in text are not converted to UTF8.
