 Hello! Thank you for using Jupyter Notebook. We're glad you're here.
 
 Right now, you're opening an issue. Before you do, let's make sure this is the right place to post your question/issue.
 
-First, it's important to know that Jupyter Notebook development has moved into a phase of maintenance-only. There are very few people with limited time maintaining this repository. This means, we won't likely accept new features here. Instead, we recommend that you check out JupyterLab (https://github.com/jupyterlab/jupyterlab)—Jupyter's next generation Notebook interface.
+Jupyter Notebook 6.x development is in maintenance-only mode. Bugs found in Notebook 6.x and that don't reproduce in Notebook 7.x may not get fixed.
+
+Work in this repository is focused on Jupyter Notebook 7.x, the former RetroLab project. The code base for Notebook 7.x is very different than Notebook 6.x. If you can, please try reproducing Notebook 6.x bugs with Notebook 7.x using the main branch of this repository.

+We recommend that you check out JupyterLab (https://github.com/jupyterlab/jupyterlab), Jupyter's next generation Notebook interface.
 
-Here, we're looking for specific bugs in the Jupyter Notebook codebase. If you think you've identified such a bug, you can continue opening your issue here. We'd appreciate if you include as much detail as possible, i.e. links to the offending code, snapshots of the UI issue, code-blocks with your console logs, etc.
