A long list of stuff, though much of it gamepad-related in preparation for console release, improved playability of some of the more annoying missions, and made 60hz physics more fair:

Fixed Remap Controls shows controller buttons, and they are a bit blurry (only fix if it's easy)
Fixed "DO NOT DESTROY" objective text is not translated (m9-4)
Fixed text in multiple areas of Build & Destroy are not translated to its supported languages.
Fixed gamepad icons during the build section text width
Fixed B key glyph rather than the B button controller glyph showing on custom vehicles
Made Flip/Swap Vehicle prompts flash when you push the corresponding input
Fixed pause menu default gamepad selection being incorrect
Updated options menu to show LB/RB and LT/RT for swapping menus and scrolling respectively
Fixed issue with B&D Reset All Instructions not working for gamepad
Added potential null-crash fix for EntityOutline crash (m4-4 killing outlined car corpses)
Made plants kill themselves a lot faster in player collisions, and they also have 50% less mass.
Fixed “Show Controls” option still showing text for the controls
Fixed Build Mode Settings buttons being all messed up with gamepad
Fixed holding A toggling/repeating presses in the options menu
Fixed dialogue box saying “Press X to continue” but not really working that way
Fixed not being able to reset instructions for building with a gamepad
Fixed BnD mission 3-3 boxes not returning to their home when they went in the water
Fixed bridge-heavy levels not appearing to count destruction for a bit
Added a bit of HUD to the Kraken-control mission, and made the UI transitions between the states smoother
Fixed returning to Island Select often picking a random island to highlight instead of the one you just played, or being started at the spot of the other campaign
Fixed pausing the game and changing vehicle control remapping not updating right away
At 60hz physics, player takes 50% damage, structures take 25% more, and kraken is 10% slower.
Reduced enemy turret/drone HP at 60hz
Increased homing and damage at 60hz for player projectiles
Reduced earthquakes strength at 60hz
Added Secret Mode logo to intro
Added Secret Mode people to credits (and made multiple tweaks to credits)
