Stack fails to build for LTS-6.15 and LTS-6.16 on Windows due to Yaml library

[azverkan]

6.15 fails to build with this issue:
snoyberg/yaml#94

6.16 dies with this issue:
snoyberg/yaml#96

Is policy for LTS to fix regressions in older releases? Or should those releases just be blacklisted for Windows clients?

[DanBurton]

We usually treat images as immutable, and address such issues by releasing a new image in the series. (e.g. LTS 6.17) Perhaps we should also maintain an image blacklist for those with known issues.

That's what I was expecting. It is just that the nomenclature of calling it a "Long Term Support" release is a bit weird if it is not actually supported.

Well the problem is we only build stackage for Linux...

[DanBurton]

The "support" comes not from supporting a specific point release (e.g. 6.16), but rather by having subsequent releases that are backwards compatible. The idea is that if you have a trouble with 6.X, you should be able to upgrade safely to a later version in the LTS 6 series.

And 6.16 was rolled early specifically to address snoyberg/yaml#94 :)

It would be nice if someone could confirm the next yaml release works on Windows before we roll 6.17...

(FWIW personally I don't think the name "LTS" makes so much sense either, but it has kind of stuck now - and I don't have a better name... :-)

[azverkan]

The word "release" has been used in this context for quite a while now and the typical short version "rel" I have seen in use for various projects going back at least 20 years :)

LTS-6.17 is now out with an upgraded yaml version.
