Well, the absolute most-recent tweaks (not updates) Ive installed are pretty minor: Better Switcher Position, and No Page Dots.
But the recent addition one I would recommend most strongly is SlideCut, and there is really no contest. I added it a few months ago, and it has made typing and text editing a world-and-a-half easier.
I also recently installed Cylinder, and I now use a page-swipe animation (of my own Lua-script creation) that shows the icons flipping over in place one after another like dominoes rather than sliding off the page.
Before that I installed Fully Masked Passwords, which hides the most recent character in password fields of websites and such, but does not seem to work with popups like when installing something from the App Store.
Prior to that was BatteryInfo Lite, solely to check the internal temperature.
A few more minor tweaks: Status Bar Switcher, Morse Buzz, and StatusTab. StatusTab is nice because I use fullscreen apps frequently, and I never use the Notification Center (I have it essentially disabled), and now I can quickly check the time or my battery level when in fullscreen mode just by swiping down from the top to make the status bar appear.
Two months ago I added BytaFont and started using Source Sans, and about the same time I installed rpetrichs SearchSettings which unfortunately only lets you search the current page of Settings, so it does not help you find where something is buried three or four levels deep.
And a month before that I added ActIf, but I have never actually used it.
