Some features were recently uploaded but they were developed some time ago, it's been a few months since I stopped messing for real with Steem. For the moment there's nothing more I want to do with it. Currently, the v4.2 beta doesn't offer any real emulation improvements, only features. That would be the first time for a major release...
Emulation improvements are different from features, they're far more interesting. For example, adding native support for STX disk images was interesting because there were some emulation issues to solve, but those improvements are already in v4.1.2. The Control Panel was still fun because it's a hybrid feature. DirectMusic and TCP/IP were frankly boring (probably buggy as hell too).
So until I find something fun to do or get new ideas or new emulation insights, there will be a little pause in development. Release date of v4.2 is undetermined (features must be tested).
