TLDR:
UltraCam beta 18 focuses on bringing massive improvements to the Actor Spawner, a new Hotkey system, stability improvements, less memory allocations and less memory usage overall. Beta 18 adds the ability to spawn Actors with custom Weapons/Shields/Fuses, custom health amount and a custom drop table. A lot of this should help creators with testing their own mods as well as make the spawner more fun for users to use, like now you can spawn actors with a hotkey of your choice anywhere you want! If you want to see more about the Actor Spawner 2.0 check this guide.
Beta 18 also adds json loader to the Actor Console, allowing custom enemies to be spawned with the console as well as saved from the UltraCam Menu. Beta 18 completely redid the entire input system, this is a major overhaul, each input now works as it's own object, in order to allow end-user control for every input in UltraCam, you don't like pressing P to pause the game? You can now turn that off, or change the hotkey/hotkey combination(s).
Beta 18 brings a new facial Animation system, this is meant to allow you to use facial animations for link, like smiling etc.
Beta 18 massive improves the Config system once again, making it easier to add new values as a developer, but also the code is a lot cleaner now too.
With beta 18, In order to improve stability the STD(Standard C++ library) usage has been absolutely reduced to almost none and replaced with an embed system friendly library (ETL). The NX Optimizer has been updated to add support to the new config system and currently the TKMM team is also working on implementing support for thew config system as well.
