+
+The Boxing Update
+
+This release is a hotfix for 2022.01.16.fr3.1. It fixes major bugs, including one massively impacting Termux.
+
+Changes:
+
+- sshyp now uses a symlink to the temporary storage directory, allowing for easy implementation of different temporary directories on different platforms
+    ^ the first usage of this is enabling the use of temporary storage on Termux
+- sshync now properly auto-generates its config directory 
+
+Additions planned for minor releases:
+
+** updated the manpage with more information regarding how sshyp works and how to set it up
+** ensured that it is now impossible for ghosts of entires to remain in /dev/shm
+** reduced total lines of code with small optimizations
+
+&&
+
+Planned for next major update (fr4, The sshyp Doing a Split Update):
+
+sshyp:
+** sshyp has recieved a major visual overhaul
+    ^ this includes the new file list and thematic text art
+
+sshync:
+** sshync has been split into a separate package and now has standalone functionality as a backup/syncing utility
+    ^ more details will be available in the sshync repo, once it is created
+
+&&
+
+Planned for next, next major update (fr5, The Farmer Shearing the sshyp Update):
+
+** allow for multi-client deletion... somehow (in sshync)
+** when syncing, a check is made to see if any folders are not on all devices - if the check comes back true, it is corrected (in sshyp)
+** imporove password generator to guarantee more secure results
+** enforce permissions on the server-side
+** allow for copying entire notes (not just first line)
+** ability to pass entries as arguments for more functions
+
+&&
+
+Backlog:
+
+** create separate gui frontend targetting mobile and desktop Linux
+** auto-completion on tab (currently unsure of best way to make this work)

 The Boxing Update
 
-This release is a hotfix for 2022.01.13.fr3. It fixes sshync/syncing support after the changes in the last release.
+This release is a hotfix for 2022.01.16.fr3.1. It fixes major bugs, including one massively impacting Termux.
 
 Changes:
 
-- sshync has been updated to work with the new config directory
-- sshync now uses its own directory to store the database file
-    ^ this is preperation for separating sshync into its own package
-- expanduser lines in sshyp have been simplified (no user-facing impact)
+- sshyp now uses a symlink to the temporary storage directory, allowing for easy implementation of different temporary directories on different platforms
