Hey there, sorry for the confusion here. Since this is on Nightly, we haven’t yet had the chance to publish our stable changelog with more details. That will happen likely tomorrow.
To answer your question, we have removed some low-utilized features, but mostly the changes to the context menu and @ symbols still exist – just that you can ask the agent directly for what you need.
The models have both gotten better at tool calling as well as self-gathering context. For example, rather than @git, the models can self-gather git history or use web search tools (instead of needing an explicit @web tag).
In terms of migration plans, for most of these, you can just ask the agent directly for what you need. There are a few that have been deprecated, though. Notably notepads, which we have a separate forum post for here.
