Comment 7 for bug 1717040

Oh, I must have done something wrong before, because zstd 0.5 did decompress a file compressed by 1.3 in my test. Now I can see that's not the case:

$ zstd -d snap.v1.3.zst -o decompressed #using zstd 0.5.1
zstd: snap.v1.3.zst: not in zstd format

So that shows files compressed with 1.3 cannot be decompressed by 0.5. That could be used as an argument *against* the SRU, though :) Do you have pointers showing that 0.5 was experimental, that things changed and that it should be dropped?

Checking the release notes, looks like v0.8 is the first release with the final compression format? https://github.com/facebook/zstd/releases/tag/v0.8.0
