 > #### Updates from May 2021
 > - I've entered into a contract with a generous sponsor, the [Sider Corporation](https://siderlabs.com), to update code2flow.
-> - This version runs Python3. Javascript support has been dropped temporarily. If you want javascript support for pre-ES6 projects, check out commit 258952d7123f946d320a83de3af75e7b96ea1a45.
-> - Going forward, in addition to JS, expect support for PHP8, & Ruby3
+> - Currently, Code2flow supports Python and JS. Expect PHP & Ruby in the coming weeks.
 > - The domain, code2flow.com is unrelated to this project and as far as I can tell through the internet archive, they launched their service after this repository was created. I've never heard anything from them and it doesn't appear like they use anything from here.
 > - The pip install, code2flow, has been claimed by a different unrelated project. For now, *don't install* code2flow from pip. Instead, scroll to the installation section for instructions.
