urllib3 has had probably one of it's most eventful years in recent times, especially with regards to sustainability of the project thanks to sponsors and grants.

I'm looking forward to 2020 and have many ideas for where the project is headed that I'll be sharing in a future post. For now let's review what was accomplished in 2019:

Grants and Sponsorships

urllib3 received $23,580 USD throughout the year of 2019. We're very grateful for our donators and sponsors, this year would not have been as productive without you. Thank you!

Here's the breakdown on where that money came from:

The breakdown above shows that most of our funding for this year came from grants. Hopefully we can continue this into 2020 as the major accomplishments for the project were completed as a result of dedicated developer(s) spending extended periods of time working on features.

Releases and Changes

urllib3 made 10 releases during 2019, up from only 3 releases during 2018. The highlights of those releases include:


These achievements aren't related to library features but are still super-fun to celebrate!
