Hi there –
I see that the last release on the 2.x branch was 2.6.3 (back in January 2017), and the last 3.x release was 3.12.3 (in November 2019).
Are these branches still receiving security updates? Or do I need to upgrade to 4.x to be assured that vulnerabilities will be addressed?
I couldn’t find any official statement on the status of these branches, LTS, EOL, etc.
