uscan currently, with "Uversion-Mangle: auto", applies this regex:
's/(\d)[_\.\-\+]?((?:RC|rc|pre|dev|beta|alpha)\d*)$/$1~$2/'
Some upstream projects tag prereleases as 1.2.3-BETA2 or 1.2.3-beta.2
or 1.2.3-beta-2.
I propose to use this regex instead:
s/\d\K[_.+-]?((?i)dev|pre|alpha|beta|rc)[.-]?(?=\d)/~$1/
The proposed regex is an improvement to...
* match all keywords case-insensitively
* permit trailing dot or dash after keyword
The following alternative regex covers the above, and additionally...
* stops superfluously escaping bracketed contents
(only dash may need escaping there, and not if listed last)
* lists keywords arguably more sensibly ordered
* shortens and reduces amount of capturing by use of \k
