The UM2 firmware wasn't updated for a long time, I would say the latest is 3 years old or so.


The Firmware is bundled with Cura so when you connect the printer via USB you can update it, no need to download it first.

    The latest UM2(+) firmware is included with Cura and had its last update with the Cura 3.3 release in April 2018.


    There is also a beta version which fixes some bugs but never made it to an official release:

     https://github.com/Ultimaker/UM2.1-Firmware/blob/UM2.1_JarJar/releases/beta/MarlinUltimaker2plus_20181007.hex  (right click on link, and then 'save link as').


    These are the changes compared to the v3.3 Cura release:

    Copied stepper module fixes from UM3 / Open source Marlin project. These fixes solve the problem where during fast movements you sometimes heard a loud tick sound like some mechanical hiccup was occurring.
    - Fix: the multiply routine could have an overflow, solved by adding a 24x32-bit routine
    - Fix: ensure the stepper interrupt triggers immediately again when it takes too long.
    Improve material import:
    - Fix: a material name length of 8 (or more) would crash the printer. Now consistently allow a length of 8 characters everywhere.
    - Fix: illegal values for the material retraction-length and retraction-speed are now set to default values.
    - Change: Improve error handling for very large positive or negative numbers.
    Other changes:
    - New: added Tough PLA (TPLA) material profile.
    - Fix: retract at end of print. Contributed by TinkerGnome.
    - Fix: another bug with retraction at end of print. If we were already retracted (G10), then we were retracting too much.
    - Fix: M117 was missing a character when printing via USB. Cherry-picked from UMO repository. Contributed by AmedeeBulle
    - Change: Changing material during a print is made 15 to 30 seconds faster by removing an unneeded filament heat-up (the filament is already hot).
    - Returning from the preset menu did not set focus on the preset menu (1 off)
    - Several trivial beautifications.
