However, this release also +fixes all known Year 2000 (Y2K) bugs in zsh 3.0. + +History changes: + - whitespace between words is ignored in history searches. + - new option HIST_REDUCE_BLANKS removes extra whitespace in the stored + history. + - support for reading (but not writing) version 3.1.6 history files. + +Globbing changes: + - the a, c, and m glob qualifiers can now test time in seconds. + - globbing of number ranges behaves more like character ranges in that + it can match a prefix of a number, e.g. `<1-5>*' matches 1, 2, 3, 4, + 5, 17, 23skiddoo, 5986, etc., but not 6, 7, 8ball, 911, etc. + +Parameter and expansion changes: + - expansion of ~ and other globbing flags via ${~param} do not depend + upon EXTENDED_GLOB (bug fix). + - nested parameter substitutions require braces (this was always the + documented behavior, but previous parsers didn't enforce it). + - quote only nested expansion, e.g. ${(f)"$(<file)"} reads complete + `file', then splits lines into array. + +Builtin and function changes: + - `typeset -U' works on the colon-array version of linked parameters. + - `typeset +f' and `functions +' output the names (only) of functions. + - `emulate -L' has the effect of `setopt localoptions'. + - in fn1() { local foo; unset foo; foo=bar; }, foo is restored at local + level, whereas if the `unset foo' appeared in a nested function it + would have been restored at global level, which was presumably wrong. + - `foo=bar >&file' is a redirection, not a NULLCMD. + - any single complex command, such as `case ... esac', parses as if + semicolon-terminated (bug fix). + - the shell function `preexec', if defined, is run after parsing each + command line but before executing the command. + +Other changes: + - the option PRINT_EIGHT_BIT causes zsh to emit raw bytes in prompts + and completion lists even if the system ctype(3) package says that + those bytes are not "printable." + +Debugging enhancements: + - LINENO is now very much more useful in scripts and functions and is + reported correctly in most error messages. + - ERREXIT behavior is now consistent with newer Bourne-like shells, + e.g. with respect to `if' tests that fail. Configuration changes: - Large file and 64-bit integers on 32-bit machines supported where provided by OS. - - generation of signal names should be more reliable - - Customizable installation of shell functions from distribution. + - a few more system features, such as getpwnam/getpwuid, are tested for.
