v2.4

This release introduces a strict mode for variables, new builtin, performance improvements, and better error messages; plus a potential breaking change

There are a number of new features in this release

Breaking Changes:

mkarray (a et al) no longer returns an error if the start and end ranges are the same. Instead it returns an array of 1 value.

User Facing Changes:

Strict variables now supported (like set -u in Bash). This will mean any variables passed that haven’t been initialized beforehand will cause that pipeline to fail. Currently this is opt in, a future release of Murex will flip that and make it opt out. So take this opportunity to enable it in your ~/.murex_profile and test your scripts. Enable this via config:
```
config: set proc strict-vars true
```
This feature was requested in issue #380.
New builtin: datetime. This builtin allows you to convert date and/or time strings of one format into strings of another format. datetime is a supercharged alternative to the UNIX command date aimed at making scripting easier.
mkarray (a et al) now supports dates. eg [01-Jan-20..05-May-21]. If no start nor end date appears then mkarray assumes range starts or ends at current date.
openagent profile for image data types has been improved. Murex now better supports tmux and iTerm2.
runtime --config now displays FileRef for every set as well as define, named FileRefSet and FileRefDefine respectively. So you can now easily trace where global config is being set and defined.
Better error messages in the interactive terminal.

Prompt now defaults to only displaying current directory rather than the full path. You can revert this change by adding your own prompt in config. eg:

config: set shell prompt {
    out "{RESET}{YELLOW}${pwd_short} {RESET}» "
}

config: set shell prompt-multiline {
    let len = ${pwd_short -> wc -c} - 1
    printf "%${$len}s » " $linenum
}

Parser updated to better support multiline pipelines where the newline is escaped and a comment exists after issue #379. This only applies to shell scripts, the interactive terminal hasn’t yet been updated to reflect this change.
Fixed regression bugs with autocomplete parameters that affected some dynamic blocks.
readline now caches syntax highlighting and hint text to improve the responsiveness of the interactive terminal. This is set to a hard limit of 200 cached items however that will be a configurable metric in a future release. Also planned for the future is caching autocompletion suggestions.
Loading message added for the default profile, ie the one that is compiled into and thus shipped with Murex.
Fixed bug with fid-list and jobs where they were outputting the p.Name struct rather than p.Name.String(). This lead to the process name appearing garbled under some circumstances.
{BG-BLUE} emitted the wrong ANSI escape code, this has been corrected.
Several readline bug fixes.

Non-User Facing / Maintenance Changes:

Thread safe copying of parameters upon fork. The previous code never actually generated any race conditions and I don’t think ever could. However it was ambiguous. This new code makes the copy more explicit and appears to have also brought some minor performance improvements in benchmarks too.
Behavioural test framework has been refactored to make it easier to add new behavioural tests.
Lots of new tests added.
Updated documentation.
