The mosquitto repository is now hosted on github: https://github.com/eclipse/mosquitto This is now the canonical location for mosquitto development work.
Bug reports should also be made on github and the existing bug reports will be migrated over shortly.
The documentation still needs updating with the new location and processes, so please do be patient with regards that.
Contributions can now be made through a github pull request. If you want to contribute a bug fix, please base your work off the "fixes" branch, if you are developing a new feature please use the "develop" branch.
Here's to a new stage in the mosquitto project!
