Expansion of such parameters must use braces, +that is, in ${.param.name} form. Parameters so named are excluded from +`typeset` and `set` output unless explicitly listed in `typeset` arguments +or matched by a pattern with `typeset -m`. + +Interpretation of exclusion-patterns following alternation-patterns has +been rationalised. This means for example that `[[ ab = (|a*)~^(*b) ]]` +is true where prevously it was false. + +Improvements to handling of terminal colors and attributes in prompts +may change the behavior of some prompt sequences, most notably in +cases where `esq=${(%)...}` is used to capture an escape sequence. + +The `which` and `functions` commands output function definitions in a +format independent of the MULTI_FUNC_DEF option. + +Math context no longer interprets a leading underscore as part of a +numeric constant. + +Nul and characters greater than \x77 are correctly handled by `read -d`. + +Return values of `sysopen` from the zsh/system module have been updated +to be more similar to other commands in that module. + +The `watch' parameter and `log' command have moved to an autoloaded module. + +Tied parameters created with the zsh/db/gdbm module may not be re-tied +as locals in nested function scope. This prevents database corruption +when a function scope ends. + +Many Completion/ functions have been updated to recent versions of their +corresponding commands, so the results offered may have changed. + Incompatibilities between 5.8.1 and 5.9 --------------------------------------- |
