Public bug reported: We discovered a bug [1] that is present in all version of Blosc from 1.11.0 to 1.13.5 (inclusive). The bug prevents data compressed with these versions using the LZ4, LZ4HC, Zlib and Zstd compressors from being decompressed using any prior versions of Blosc (it's an accidental forward-compatiblity break). So in a sense, these versions should be considered bad apples.
The bug was subsequently fixed [2] and the fix is present in the now released 1.14.0. The upstream author also blogged [3] about this incident. I alerted the Debian package maintainer (Daniel Stender) about this [4], and he was kind enough to quickly package the bugfixed version [5]. I therefore ask you to please sync this bugfixed version to bionic, since it would be unfortunate if it was released with one of the "bad" versions. Many thanks in advance!
