That means that python 2.7 should be dropped as well, right?

[AbhiPrasad]

We probably can’t think about dropping 2.7 support, a ton of users still rely on it.

It is important to note that 3.5 and 3.4 might stick around for a while. This issue exists to make sure we adequately track progress when we eventually make the decision to phase them out.

I understand it, I was just interested because of the linked page. Do you have public sentry specific python version usage stats available?

[beliaev-maksim]

it is important to track down the version of the package used. For example PyPi tracks Python version (eg 2.7) but lots of projects with Py27 are frozen/security maintenance projects. So, most probably they are not interested in new features and new stats are triggered by pipelines or package is installed but using some old fixed version.

We will drop Python 3.4 support. (This will happen in the next 2-3 months) Python 2.7 and 3.5 will live on a bit longer, because a lot of Sentry users still use this versions.
