I stumbled across this email from Travis CI on another project’s tracker (emphasis mine):
In an effort to ensure that all of our users - whether you build open-source, public or private repositories - receive regular feature updates, security patches and UX/UI enhancements, we are announcing that travis-ci.org will be officially closed down completely on December 31st, 2020, allowing us to focus all our efforts on bringing new features and fixes to travis-ci.com and all of our awesome users like yourself on the travis-ci.com domain.
I didn’t receive this email; couldn’t find anything on https://blog.travis-ci.com; and the FAQ doesn’t mention the new year deadline, nor any other deadline:
Please could you confirm this deadline, and publicise it more widely? For example, send the mail out to more people, put it on your FAQ and blog and other channels.
