I've never noticed it, but this comes directly from upstream tarball.
We probably also re-touch it when downloading the stage0 snapshot.
I'm not sure if this has already been reported upstream...

Cargo too, but IIRC jquery2 is not packaged at the moment.

It is computed at runtime, see mk/main.mk:
"""
# Append a version-dependent hash to each library, so we can install different
# versions in the same place
CFG_FILENAME_EXTRA=$(shell printf '%s' $(CFG_RELEASE) | $(CFG_HASH_COMMAND))
"""

It is basically a truncated md5 of the version string.

Yes I agree that it is a bit ugly in the long term.
Braindump: can we introduce a generic versioned provide (without the hash 
suffix) and breaks on that instead, based on version?

Cheers, Luca
