This is primarily a bugfixes release. However, it does add a new bonus mission. This mission is unlocked after completing mission 200 "Chrysalis". If you've
already completed that mission, you'll need to clear it again to trigger the
unlock; the "Win Mission" assist should be sufficient.

Gameplay:

Improved handling of extremely wide aspect ratios

Missiles are drawn in the short-range radar

Slightly tweak the briefing for mission "The Cat's Away"

Several new parts added, associated with the new bonus mission

The 4" 50cal gun and QF 4" guns use the same ammo

AI ships should be a bit better at avoiding collisions

New weapon: "Squid" ASW mortar

Sinking projectiles sink twice as fast

Autofire weapons that are targeting regular ships (i.e. not planes or PT boats) now focus-fire instead of distributing across multiple targets

170mm and 250mm gatling weapons now have proper masses and ammo counts

Bugfixes:

Autofire guns should not be able to fire before the mission starts

You no longer need to manually re-enable all workshop mods each time the game launches

Fixes to the mission "Storm Descendant":

Fix tripods not spawning

Fix tripods being active during cutscenes

Fix autofire weapons not shooting at tripods

Hopefully fix a bug causing the music to cut out

Fix briefing music playing over the cinematic

Fix a bug causing "noShortNameDetected" ammo counts to be displayed in the mission summary

Fix main guns refusing to fire on the second form of the Apotamkin boss

Hopefully fix ships getting paradropped onto land

Fix missing objective in mission "Shadowy Waters"

Fix certain buildings being active from the start of the mission in "The Cat's Away"

Fix flag strands breaking if the "Lights" style was ever selected

Fix York and Mogami underdecks being too small

Adjust Quinn's "happy" portrait so that their chair doesn't slide around during dialog

Fix the options UI always showing the difficulty settings

Fix the Denali's spotlights having poor freedom of movement

Ship thumbnails (shown in the load-ship screen) are now higher-resolution. Unused ship thumbnails get deleted when a new ship is saved. If no thumbnail can be found, a default image is shown.

Flagged several weapons with belowdecks collision as being unable to be placed on superstructure

Fix the loading bar overestimating how much needed to be loaded

Fix autofire weapons sometimes aiming at the wrong part of the target

Fix being unable to build on part of the Portland aft bridge

Modding:

Added a flag to specify that a hull should be immune to being cut in half (when the ship dies)

Missions can now set and unset flags, and then use those flags as part of mission triggers

[*]Weapons can be flagged as automatically exploding when they hit their maximum depth
