generally, 'out-of-date' are not bugs, nor packaging requests - there could be a category for them on the bug tracker; but there is not, intentionally - for existing packages, which could be upgraded to a new upstream release, the 'out-of-date' flags on the packages website is the proper mechanism, for users to indicate that

that alone, justifies closing this ticket; but i will make an exception, to explain/address the request, for the sake of documentation/education/pedantry

the standard arch 'prusa-slicer' is version 2.3.3 - the parabola mission statement promises to keep in sync with arch, whenever possible; so 2.3.3 is the correct parabola version today - there are no open bug reports for that package (arch nor parabola); so 2.3.3 is the only version, which parabola users should want to use today - new upstream releases of that software are not significant to parabola; because that package is managed exclusively by arch

the package is flagged 'out-of-date'; so the new upstream release is probably known to the arch maintainer already - the arch package is only one month old though; its upgrade is probably not urgent - generally, the package maintainer knows best, how to maintain each package - new upstream releases are not always desirable, for the sanity of the OS as a whole

the most important misconception to clarify though, is that upstream releases are generally not interesting to any typical user of the OS - the arch 'out-of-date' flags mechanism, is not a common feature of distros - it mainly indicates that arch has a high percentage of atypical expert users, who are willing to help the maintainers - ie: most arch and parabola users can simply ignore the versions of everything - they are truly irrelevant/inconsequential to the experience of most users

• out-of-date packages are not packaging requests for the bug tracker
• users may notify package maintainers of out-of-date packages, via the packages website
• the package maintainer knows best, how to maintain each package
• most packaging decisions are made by arch
• parabola keeps in sync with arch software
• parabola will normally not over-ride arch's packaging decisions
• newer is not always better
• it is wiser to prefer "better", where ever that differs from "newer"
• the 'out-of-date' flags are non-essential; but purely informative (an "advanced nerd thing")
• most users of most distros, are rarely affected by versions of anything, so can ignore versions
• the previous point is true, precisely because the packager may decide that the newest upstream release, is not the best version for the system, as it is, at the time
