This change brings a number of ergonomic improvements to job control, datetime and working with structures.

Deprecation Warnings

Please read out compatibility commitmentopen in new window to understand how features are deprecated.

the ? pipe will be deprecated to make way for a the ternary operator. You can achieve the same result with <err> <!out>, eg command <err> <!out> parameters... | next-command ...
the = and let builtins are now officially deprecated. They've been marked as deprecated in the documentation for a couple of years but you'll now receive a deprecation warning when using them. This warning will not impact any functions that call them (they bypass the stdout and stderr pipes and write directly to your TTY) but it is still recommended that you update any existing code not to use it. The change is very simple, Murex supported expressions as first class primitives, so you can simply drop the = and let command names from your expressions
tread has been deprecated for a while due to read supporting all tread's use cases. tread will officially be removed in the next release
@[] syntax for ranging has been deprecated for a while. It will be officially removed in the next release in favour of []
backtick strings (````) has been an undocumented hack for several years. This release officially sees that hack as deprecated and will be removed in the next release
die has been deprecated because it just adds a feature for no purpose. It was original borrowed from Perl but realistically you can do the same with exit 1 so this removal is to bring the language complexity down.

None

runtime: new flag: --about reports information about the Murex system. Useful for debugging (issue #896open in new window)
runtime: --go-gc now forces the garbage collector to deallocate memory rather than just marking memory as unused (issue #896open in new window)

expr fix panic when using parentheses in dot notation (issue #892open in new window)
versioning: only auto-version if $MUREX_DEV is set
versioning: 0 pad semver revision to 4 characters

IO redirection: smarter file pipes which solve the race condition seen in traditional shells where you try to write to the same file you're reading from (EXPERIMENTAL) (issue #851open in new window)
private functions: these can now be undefined (issue #429open in new window)
core: (expressions) are supported in dot notation. eg:
```
» bob = %[foo bar baz]
» out $bob.(1+1)
baz
```
elements: negative values are supported for counting backwards. eg:
```
» bob = %[foo bar baz]
» out $(bob.-1)
baz
```
core: support added for Bash-like job IDs (%n) in job control (issue #889open in new window)
bg / fg: support for command line parameters, as well as Bash-like job IDs (issue #889open in new window)
function: support for optional parameters when using named parameters (issue #888open in new window)
autocomplete: improved autocompletion for kill (issue #867open in new window)
datetime: numerous ergonomic improvements (read moreopen in new window, commitopen in new window)
readline: MaxTabCompleterRows is now more granular (commitopen in new window)
mxtty: updated csv support (commitopen in new window, read moreopen in new window)

private functions: mutex added to mitigate a potential race condition (issue #883open in new window)
core: line numbering bugfix (commitopen in new window)
readline: when in Vim mode, a and A should move the cursor right (commitopen in new window)
index: support for null values (commitopen in new window)
core: improvements with how raw command line parameters are passed to internal routines, which fixes a number of reporting bugs in process management tools

Thank yous for this release goes to tiymatopen in new window, atagenopen in new window for your testing and feedback.
