> Light Table will continue to go on strong. We haven’t talked too much about it lately, but it’s used by tens of thousands of people and still growing. We use it every day to help us build Eve and thanks to the awesome people in the community that has sprung up around it, it gets better every week.
Judging by GitHub contribution data (https://github.com/LightTable/LightTable/graphs/contributors...), it seems there has only been 25 commits (from one author) since Sep 20, 2019.
The LT blog also had a few updates as the community drove the project forward for a few more releases.
