+sshyp 2022.02.16.fr4
+
+The High-Tech Shears Update
+
+This release adds in a major feature: multi-client deletion (details below)
+
+Note: This release requires the configuration ("sshyp tweak") to be re-done, as a device name now must be set (for multi-client deletion).
+
+Features:
+
+- added multi-client deletion
+    ^ this means that when an entry is deleted from one client (and thus the server), if another client that has a copy of the deleted entry tries to sync, instead of re-uploading the deleted entry, it will now also have its entry deleted.
+    ^ the current implementation requires a new Python script in addition to sshyp and sshync
+
+Changes:
+
+- fixed an issue where sshyp would use the wrong SSH key when trying to delete entries from or create folders on the server
+    ^ this is a fix that was recently applied to sshync - turns out I made the same mistake in sshyp
+- deleting folders should now work properly with "sshyp shear" if the directory is entered with a following "/"

 .SH LIMITATIONS
 The following limitations will be corrected in future updates:
 
-Currently, if multiple clients are connected to a single server and a client deletes an entry, the entry is correctly deleted from the client and the server, but since the entry still exists on the other client, the next time it syncs the file will be re-uploaded. This will be fixed in an upcoming release of the syncing backend, sshync.
+    Currently, folders (for sorting) are not replicated onto new clients (they need to be manually created before syncing).
 
-Currently, folders (for sorting) are not replicated onto new clients (they need to be manually created before syncing).
+    Currently, the entry list displays each entry with the file extension ".gpg" visible (which you do not type when reading, modifying, or creating an entry). This will be corrected when the new entry list is added.

 .SH SETUP
 sshyp operates on a client-server model, and thus requires you to have access to your own server (whether it be a physical home server or a cloud rental) with remote access via SSH.
