What
The command parser now refuses to parse two [[ ]] shapes where zsh's cond-lexer disagrees with the parser, classifying them as too-complex differential cases instead.
Details
a [[ ]] pattern leaf containing && now bails out, because zsh splits the word there
a pattern leaf containing a potential standalone ]] closer also bails out, because zsh closes the conditional differently
the nodeType field was dropped from the unbalanced-parentheses result
Evidence
shell cond-lexer divergence (zsh splits the word there)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
