News

Some netizens asked about follow-up updates in Issues. Here is the reply:

There are many things going on this year, so the progress is very slow. I am not sure whether I will abandon this project. The main reason is that the author has limited energy. Please forgive me. The original intention of initiating this project is to learn more about IM server development. If there is a better IM project implemented in open source Go language, I may consider participating as a contributor.

Finally, I would like to post some recent updates to thank everyone for their concern.

Client

Supported clients are:

Under development (V2)
- Android: Based on android 7.0 + java implementation, currently under development (August 2022), suitable for V2版本server.
