+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`.

+* Editing a system tiddler that links or transcludes another tiddler no longer adds it as a [[backlinks|backlinks Operator]] or [[backtranscludes|backtranscludes Operator]] source; the incremental back-index update now skips system tiddlers like the initial scan always did

+`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.
