 - Improved how AI Studio indexes large local data sources. It now works through them in steps of a few minutes, so your other data sources, such as your mailboxes, stay up to date in between.
 - Improved the plugins page with the details of each plugin. The info button next to the name of a plugin shows, among other things, its version, its authors, and where to get support.
 - Improved the details of a plugin on the plugins page, which now show when the plugin was last changed, in your time zone. Plugin authors can state this time, and AI Studio fills it in by itself when it writes a plugin for you, for example, with the Assistant Builder.
+- Improved local data sources for folders. You can now choose which files AI Studio indexes, for example, only PDF files, and whether it includes subfolders as well as hidden files and folders. By default, AI Studio now also indexes text files it did not recognize before, such as program code of any kind or a LICENSE file, so a Git repository makes a useful data source. Thanks, Paul Koudelka (`PaulKoudelka`), for this contribution.
+- Improved local data sources for folders, which now leave out hidden files and folders as well as build output and downloaded dependencies, such as the folders `node_modules`, `bin`, and `obj`. You can change this in the expert settings of the data source. When an existing data source contains such files, AI Studio removes them from its index during the next update.
+- Improved the background embeddings page, which now lists the files of a local data source that AI Studio left out, for example, images or files that are too large. It also shows which file types and folders lie outside what the data source selects.
+- Improved the Batch Processing assistant, which now leaves out hidden files and folders as well as build output and downloaded dependencies, such as the folder `node_modules`. You can change both in the expert settings of the assistant.
+- Improved local data sources for folders and the Batch Processing assistant, which now leave out files larger than 1 GB, such as images of virtual machines. You can change this limit.
+- Improved the organization-wide management of the Batch Processing assistant. IT departments can now preset whether it includes hidden files and folders, which files and folders it leaves out, and how large a file may be, either fixed or as a default which users may change.
+- Improved attaching files to a chat. You can now attach any file that contains readable text, for example, program code or configuration files of a kind AI Studio did not know before.
 - Changed the banner on the start page to a fresh design that shows what AI Studio can do today.
 - Fixed a warning about the confidence level that stayed in the dialog for adding a local data source, even after you chose an embedding provider that meets it. The dialog now checks again whenever you change either of them, so a warning also appears when you switch to a provider that falls short.
+- Fixed the list of data sources squeezing their names into a very narrow column when you opened it from a chat or from the background embeddings page, so the names were hard to read.
 - Fixed two confidence levels sharing the same name in the German user interface. Moderate is called "Mäßig" again, and Medium stays "Mittel".
 - Fixed renaming an external data source (ERI server) leaving its secret behind under the old name in the keychain of your operating system.
 - Fixed the ERI server assistant deleting files in a folder you no longer used. When it updates a server, it deletes the files it created before, and after you chose another folder for the server, it also deleted them in the old one. It now only deletes files within the folder you chose.
