Rename Outdated to Legacy

We don't use legacy that way in the US.

"legacy" is just a euphemism for "outdated". We picked the latter for a reason: to discourage its use.

But feel free to use "legacy" in the en_GB translations ;-) (I may need to 'unreview' it for that, just let me know)

Brainstorm:
Previously used suffix for v2.x
Formerly in use
Old-fashioned // It's not about wh1skey
VSOP //Yes, It's about br4ndy and it has nothing to do with the issue :)

More brainstorming:

• "deprecated"
• "obsolete"

"deprecated" usually means that the option will go away one day. Here the oposite is true, it got (re-)added.
"obsolete" doesn't really cut it either, there's still pleny of programs that produce these types of files.
"Legacy" (and "vintage" ;-)) are just euphemisms, marketing speak.
I do prefer to call a spade a spade rather than a manual excavation implement and therefor still support "outdated".

I've never heard "outdated" used in a technical sense. It is more for figures of speech, fashions, ideas or methods since discredited, abandoned, or disproven. "Legacy compatibility" is my suggestion.

Because there's all this marketing nonsense, esp. around the commercial products.
Your proposal is just way too long.
Maybe "out-of-date". Although I don't see the difference to "outdated" there

"Legacy" just have a way too positive conotation, like your example perfectly demonstrates. At least one meaning of "legacy" is "heritage" or "inheritance". Doesn't fit here at all.

Howbout just :"(Old format)"

Not negative and discurraging enough.

How about "stale"?

In computing, a legacy system is an old method, technology, computer system, or application program, "of, relating to, or being a previous or outdated computer system," yet still in use. Often referencing a system as "legacy" means that it paved the way for the standards that would follow it. This can also imply that the system is out of date or in need of replacement. – Wikipedia

Thanks. That was my feeling, but I never thought of asking Wikipedia. "Legacy" is perfect.

It is the marketing term for outdated. An euphemism.

In UK English it is more than that and it's perfect for this situation. Perhaps other languages use a different term for such computer systems.

The string being discussed here though is supposed to be American English, just like all the strings in the sources of MuseScore. "Translating" it to "legacy" for British English is still possible.
Although IMHO American English is even more prone to use Euphemisms than British English.
As said already, "legacy" also means "heritage", and that doesn't fit here, not in its positive conotation.

But whatever it'll become, the German translation would remain "veraltet" and would never ever become "geerbt" or some such.

Many words have several shades of meaning but each shade does not have to apply in every sematic context.

We have a couple of legacy systems at work but there's no connotation of "marketing" involved.

Isn't the wiki entry American?

What (inaproriate) "shade of meaning" does "outdated" have?

I was referring to "legacy" which you objected to.

I was only referring to "legacy", which you objected to.

Second best option: "obsolete".

Well, the legacy meaning of "legacy" is "heritage". Hence using it for something that really is outdated is a euphemism.

It's anything but a euphemism:

In computing, a legacy system is an old method, technology, computer system, or application program, "of, relating to, or being a previous or outdated computer system," yet still in use. Often referencing a system as "legacy" means that it paved the way for the standards that would follow it. This can also imply that the system is out of date or in need of replacement. – Wikipedia

One "shade" of meaning of legacy is heritage but this shade does not apply in the current sematic context, although if this obsolete file format had led to a newer format then that shade would apply too.

It is a euphemism. You may not realize that (anymore), I'd call this professional blindness.
There are even words (and many languages) where no non-euphimist variant exists. Think of e.g. toilet, water closet, rest room, lavatory, all euhpemisms, no non-euphemistic word in sight, at least none that wouldn't be seen as vulgar (some German ones: Scheißhaus, Kackstuhl)

"legacy" has several shades maybe, but does "outdated" have any? It IMHO is very unmistakenly getting the message across that the partiticular file format (or rather: extension, .xml) is still (rather: again) there, but should better not get used, as a better alternative (.musicxml) exists.

I think that "outdated" is just fine but "legacy" is better.

Once again, "toilet, water closet, rest room, lavatory" are not necessarily euphemisms, it depends completely on the context. They are more like synonyms.

Euphemisms are often used as a substitute for something unpleasant. "Pushing up the daisies" is an English euphemism for "dead" and really has no meaning apart from this euphemism, (unless someone contrives one).

"The word toilet was by etymology a euphemism, but is no longer understood as such." - Wikipedia. So I guess that your example of "toilet" is actually outdated, but definitely not legacy.

I can never resist a discussion about English usage. I suggest that "outdated" tends to imply that the thing so described now has no utility, whereas "legacy" implies the thing has some use, even if it is old fashioned and not optimal. So an electric light shop may sell "legacy" 240 V tungsten filament lightbulbs for applications that can't use LEDs, but would not sell 110 V DC carbon filament lightbulbs as there are no fittings that require them; in other words, the 110V lightbulbs are "outdated". There is no euphemism here. The meanings are subtly different.

A well chosen example.

Hence, this is why I'm growing to like the word "stale" in this instance. "Stale" implies an element of undesirability on account of its age, e.g. stale bread.

"Defunct" : can mean no longer in use.
"Stale" strikes me as odd but appropriate. :-)

"Defunct" means: doesn't work anymore. Not suitable.
"Stale" is a pretty bad term for translators, "Outdated" though is easy to tanslate, as it has only one single meaning.

Does it even need anything in brackets? I reckon users techie enough to need this format will manage without being told that it's stale, legacy, outdated, old, rusty, obsolescent or anything else.

There are parentheses, not brackets ;-) And yes, they are needed

What are "paretheses"? ;-)

a typo ;-)

Parentheses ()
Brackets []
Braces {}

:-) Perhaps we should end this 'pedant war' :-]
