[tor-commits] [onionoo/release] Extend "version" parameter to support lists and ranges.
commit f0f57879d6074a979c33a46873ad5d9e60c6d72e
Author: Karsten Loesing <karsten.loesing@xxxxxxx>
Date: Sun Jul 29 20:01:49 2018 +0200
Extend "version" parameter to support lists and ranges.
Changes the current behavior of the "version" parameter by moving away
from string prefix matching to actually parsing provided (partial)
versions. As a result, for example, "version=0.3.2.1" doesn't
magically include versions 0.3.2.10 to 0.3.2.19, 0.3.2.100 to
0.3.2.199, etc. anymore. Without this change, version ranges would
have become just too confusing. The downside is that this change
requires a major version bump.
Implements #6947.
