December 1, 2017 release notes

Advanced filters for Aha! reports enable you to apply complex filtering rules in order to easily analyze and act on your product data.

When switching between products via the top navigation, the features list page now automatically loads the default features list for that product. It previously loaded the last accessed saved view.
It is now possible to remove a To-do's due date without having to delete and recreate the To-do.
Items that have been deleted after being added to an Aha! Notebook will now be marked "[Deleted]" when editing the Notebook.

When exporting to Excel, Windows users were encountering a warning and error that prevented them from opening the file without repairing it.
Pivot report calculations were incorrect when custom sorting was applied to them.
When presented with a login failure, users were redirected to an Aha! subdomain that matched their email address; the page now refreshes but no longer redirects the user.
When customizing a custom roadmap to color by the feature name field, the customization was not applied.
Pre-defined tag custom fields were not displaying their description when added to idea forms.
