OED is an open project where information about all aspects of the project are maintained on our GitHub site. In addition to seeing all the source code, the OED GitHub project allows one to view all known issues, to submit a new issue or comment on an existing issue. You can search all the issues to see if your concern is already documented and look at the conversation to date. An "Open" issue means it is not yet resolved and a "Closed" issue means it is resolved. Note that a closed issue may not yet be in the version of OED you are running. You can comment on a closed issue or open a new one if you feel the concern has not been adequately or correctly addressed.
OED has a Discord server with channels for general, developer and other conversations. Developers are especially encouraged to join and other are also welcome to interact with project members and the OED community.
