Gistory

If you use bundler and git and you want to know when a gem was updated, gistory comes to the rescue, simply:

gem install gistory
cd /path/to/repo
gistory sidekiq

and you'll see something like:

Gem: sidekiq
Current version: 4.2.7

Change history:
4.2.7 on Tue,  7 Feb 2017 16:05 +01:00 (commit c6edf321)
4.2.6 on Wed, 30 Nov 2016 13:47 +01:00 (commit bf6a0d17)
4.2.5 on Tue, 22 Nov 2016 14:48 -05:00 (commit 20ff5148)
4.1.4 on Wed,  9 Nov 2016 14:31 +01:00 (commit 05a3c549)

By default gistory only looks at the last 100 commits made to the current branch. If you want to see farther back in the past run:

gistory sidekiq -m1000

If you want to look at all changes to Gemfile.lock in all branches, use the -a switch:

gistory sidekiq -a

Note that if the gem was added, then removed, and then added again, gistory will only show the latest version changes up until it was removed.

Roadmap

use red for changes in the major version, blue for changes in the minor version
support other VCSs like subversion, mercurial, etc.
detect if the gem was added, then removed and then added again
use a libgit2 binding instead of the git cli, how much faster it is?
remove bundler dep
add yard doc
do not print the warning text if there were no more changes in the lock file
link the commit SHA to the repo's hosting service, if any
