BUG FIXES

- Fixed a bug where the nudge part inputs would not work until the transform part panel was opened
- Fixed a bug where the download progress bar would report very high values on Mac
- Fixed bug which could cause the propeller engines to hunt for target pitch and never be able to reach it...could cause wild swings in lift.

- Fixed a bug where the fuselage properties would revert player's input text if their number ended in a zero.

MODDING SUPPORT
- The build process and format of mods has slightly changed. When building mods for Windows/Mac, Unity will need both the Windows and Mac build components installed (mod tools should warn you if this is not the case). PC/Mac mods now include separate asset bundles for both platforms in a single mod file. You will likely noticed larger mod file sizes with this update. A new 'Debug' build option is available which builds the mod only for Unity's current target platform with the DEBUG symbol defined (should be a faster build than the other build options).
- A bunch of classes received interfaces which have been added to the mod tools. You may be able to get away with using less reflection code by taking advantage of these interfaces. These live in the "Jundroo.SimplePlanes.ModTools.Interfaces" namespace.
- Fixed a bug with the starting locations reflection proxy code which may have caused the spawining of AI aircraft to fail.
- Fixed a bug with mod level duplication when saving mods.
- Fixed a bug that prevented the cloning of parts with a hinge joint.
- Mod Builder Window style/layout tweaks
- Some additional info on changes and upgrading can be found on the modding wiki

POTENTIAL MOD-RELATED ISSUES
- Since we updated Unity with this upgrade, several mods are likely to be broken. For this reason, mods will be automatically disabled the next time you start SimplePlanes. Nathan has been able to find some very clever ways to allow some mods to still function, but several mods will be broken with this update. We recommend turning them on one by one and testing each one to verify whether or not they still functions and don't cause any problems.
- Changes since last beta

BUG FIXES
- Fixed collider misalignment on helicopter blades
- Fixed issue w/heli blade collider being incorrect when the hub is scaled.
- Fixed a bug where the camera could move wildly after un-pausing.

Simpleplanes 1.11 "An Inside Job"

Normally, this is the part where a helpful user would post the body of the update in a neatly organized list.
But since Jundaroo have already helpfully done that and the changelist is quite massive, I'd like to encourage you to peruse this yourself.

SimplePlanes 1.12 "Now in VR!"

Along with the VR support (superfluous I presume, on GOG), there are a number of minor tweaks and changes.

https://www.simpleplanes.com/Blog/View/1829113/v1-12-200-beta-is-now-available

Rest well, Simpleplanes. I imagine that due to Unity's lacking any sense, that this will indeed be the final SimplePlanes update.
