JQL: Allow fuzzy matcher for versions (fixVersions, affectedVersions)

The tasks I have (actually via Rest API currently) in a project containing issues for version branches 1.x.x and 2.x.x:

• Find all issues in the latest released version 1.x.x of project ABC
• Find all bugs in versions 1.x.x which are unresolved (known issues filter)
• Find all issues fixed in version 1.x.x

As both branches are continuously released the version management in Jira resembles to this:

• 2.0.3-SNAPSHOT (next 2.0 release)
• 1.0.13-SNAPSHOT (next 1.0 release)
• 2.0.2 (latest release)
• 2.0.1
• 1.0.12 (latest 1.0 release)
• 1.0.11
• 2.0.0
• ...

My only idea: JQL should support fuzzy matching for versions. Examples for the three examples above:

• Find all issues in the latest released version 1.x.x of project ABC

  project=ABC
    AND fixVersion in latestReleasedVersion("ABC","~1.")
    AND resolution = Fixed
  

  I think it makes most sense here to extend the JQL function latestReleasedVersion. If the fuzzy operator should be part of the string I don't know. I think the assumption is totally valid that all strings specified here are for fuzzy matching so the prefix could be skipped. Unclear: How to extend latestReleasedVersion to find all released 1.0 versions across all projects? Perhaps: latestReleasedVersion("*","~1.")

• Find all bugs in versions 1.x.x which are unresolved (known issues filter)

  project=ABC
    AND type=Bug
    AND (affectedVersion in releasedVersions("ABC","~1.")
      OR affectedVersion is empty)
    AND resolution = Unresolved
  

• Find all issues fixed in version 1.x.x

  project=ABC
    AND fixVersion ~ "~1."
    AND fixVersion in releasedVersions("ABC")
    AND resolution = Fixed
  

  alternatively:

  project=ABC
    AND fixVersion in releasedVersions("ABC","~1.")
    AND resolution = Fixed
  

As you can see most of the time (for my use cases) it is sufficient to extend the JQL functions releasedVersions() and latestReleasedVersion().

If it is easier to implement a new JQL function than you could introduce: matchesVersion("ABC", "1.". So for example the last JQL query would look like this:

project=ABC
  AND fixVersion in releasedVersion("ABC")
  AND fixVersion in matchesVersion("ABC", "1.x")
  ...

But I think this approach will not work nicely for to find the latest released version.
