+The <<.op makepatches>> operator uses up to two suffixes:
+
+* <<.place T>> (diff mode): `lines` to operate in line mode, `words` to operate in word mode. If omitted (default), the algorithm operates in character mode.
+* <<.place F>> (output format): <<.from-version "5.5.0">> `json` to output a structured JSON array of differences instead of a standard patch string. To use the JSON output with the default character mode, skip the first suffix with a double colon (e.g., `makepatches::json`).
+
 The difference algorithm operates in character mode by default. This produces the most detailed diff possible. In `words` mode, each word in the input text is transformed into a meta-character, upon which the algorithm then operates. In the default character mode, the filter would find two patches between "ActionWidget" and "Action-Widgets" (the hyphen and the plural s), while in `words` mode, the whole word is found to be changed. In `lines` mode, the meta-character is formed from the whole line, delimited by newline characters, and is found to be changed independent of the number of changes within the line.
 
 The different modes influence the result when the patches are applied to texts other than the original, as well as the runtime.
 
 <<.tip "The calculation in `words` mode is roughly 10 times faster than the default character mode, while `lines` mode can be more than 100 times faster than the default.">>

+description: A field name containing round brackets can no longer be used as a filter operator suffix, because `(` now starts a multi value variable operand.
+
+Two filter operators take a field name in the suffix position: `regexp` and `search`. Up to 5.3.8 such a field name could contain round brackets, for example:
+
+```
+[regexp:_cd-work(s)[(?i)suite]]
+[search:_cd-work(s)[suite]]
+```
+
+In 5.4.0 the new `(varname)` operand syntax for [[Multi-Valued Variables]] makes `(` start an operand. The parser now splits such a field name at the `(`, so the filter no longer matches.
+
+This will not be fixed. The two readings of `field(x)`, a field named `field(x)` versus the field `field` with the operand `(x)`, are genuinely ambiguous, so `(` and `)` are reserved in filter operator names and suffixes from 5.4.0 onwards.
+
+Workaround: do not use `(` or `)` in field names that are referenced as a filter operator suffix. Rename the field, for example `_cd-works`.

+
+`getCellInfo` read its loop variable before the loop declared it, so hoisting made it undefined and the parser tested the first character of the whole text rather than the first character of the cell. Any CSV opening with a separator therefore returned every cell empty, and the table rendered blank.
