In particular, writing Text Editors requires tracking lots of information and changes from various sources. Sometimes those changes come from 2nd-degree objects via the object you really care about.
To make that easier, we now have GSignalGroup and GBindingGroup merged directly into GObject. At their core, they allow you to treat a series of signals or bindings as a group and connect/disconnect them as a group. Furthermore, you can use g_object_bind_property() to bind the target instance to the binding/signal group removing even more code from your application. More than likely you’ll be better about supporting how things can change out from under you too.
In the process of upstreaming these objects, we did a bit of hardening, API cleanup, and thread-safety guarantees.
Now, go and delete some code!
