@brunobord is this ok for merging?

[brunobord]

On hold for the moment, I need to fix the Python 3.4 incompatibility.

[brunobord]

I dislike the fact that this PR introduces the dropping of Python 3.4. I see in other jobs that there's an issue with pandas ; so I'll try to find a way to solve this incompatibility more gracefully, and see if this sunsetting of Python 3.4 is necessary.
I'll keep you posted.

@brunobord good job!

[brunobord]

Please do not put new version numbers and/or release dates here.
You should rather add the "new calendars" section and your changelog item to the "master" list.
When it'll be ready, I'll make the proper release, etc, don't worry.

all right

[brunobord]

All right, so master is now Python 3.4 - ready, so you can rebase your branch from master (or you may checkout the upstream repository, and cherry-pick your commits and make another pull-request if you prefer).
You would pay attention not to remove the py34 job environment and edit the changelog file in accordance to my latest remarks.

Thank you for your nice contribution, we're almost there! :o)

updated

Looking good, now. No offense, but I'm going to retrieve your branch locally, squash commits in order to have a cleaner history. Don't worry, your work on this calendar is still ACE and I can't thank you enough for this HUGE bump in the global population that will be able to use workalendar!
