I would argue that the version is actually often important - there have been significant changes through the versions and I certainly would not expect any but the most generic (as in, "would apply to any Linux distro") answers for a ten year old version to work perfectly on a recent release.
Just major changes off the top of my head, there's the recent ...
Ubuntu versions don't differ much.
I am by far not an Ubuntu expert and even I know that there are significant differences between a Ubuntu version released in 2009 and one released in 2019.
Having used older versions in a VM I can think of several problems that stem from using an older version, when attempting to upgrade the installation, to a newer ...
Perhaps we don't need a tag for every single version, but I agree that over time, there have been significant changes that justify some type of differentiation. But there's another key difference that justifies some form of differentiation, LTS vs. interim releases.
LTS releases are stable, built from interim releases after components of those have stood ...
I would say that we absolutely don't need so many version tags. I would argue that all we need is ubuntu and then the version can be mentioned in the body of the question. Yes, there are difference between Ubuntu versions but they tend to not be very important. Also, most of them are down to the various pieces of software bundled with the distribution.
As optical was only used on 9 questions I have gone ahead and removed it.
It was abused to be a modifier for several different things
optical lenses in 3D modelling
As such it was a meta tag and deserved burnination.
As stated by fixer external is a meta tag, meaning that it does nothing to clarify the problem except when used as a modifier for other tags. Tags should be clear, well defined and accurate rather than requiring a list of them to nail down the problem.
If a tag can be applied to almost anything then it is a good target for burnination.
A short list of the ...
Safety & security are often synonymized in non-computer fields, and to be honest they are similar in many places. Typically, people who need to know the difference, like computer security experts, know the difference, while people who have never tried to secure a system of any type from attack, like regular users (who should still know but often don't) ...
The general flow I follow when merging tags is
Propose a synonym from the individual tag page
Approve it from tag synonyms
Merge the questions from both the tags using the merge option
When following the same for the above tag, I ran into the above error. I went over to the tag synonym page, swapped the mapping & proceeded with the merge, at which ...
