Update 5.91:

- Fixed damage multiplier for the Shield Cannons vs the mod's custom materials; they were still damaging them.

Update 5.9:

- Added the 4th Ultra Cannon: the Ultra Impact Cannon
- Added custom shell eject effects to every Cannon
- Tweaked the Shield Cannons; they now have better fire arcs and stronger shields; however, the shield itself only stays around for 10 seconds, as opposed to 20 seconds
- Improved fire arcs for Flak Cannons so that they can better perform anti air
- Reduced damage for Lasers to Shields, increased it for firebeams
- Made it so that the shields from Shield Cannons do not collide with your own structure; they still however collide with your own devices, changing that would be quite complicated.

Update 5.88:

- Added beam collision to the Shield Cannons (this requires Moonshot to work); lasers and firebeams are now blocked by the shields, though they do burn through them; firebeams destroy a small amount while lasers burn through quite a lot.

Update 5.87:

- Added custom fire and shell eject effects to the Ultra Cannons

- Increased the recoil of the Ultra Cannons

Update 5.86:

- Fixed the fire cost and amount of projectiles for the upgrade version Shield Cannons

- Made it so that the Shields of different Shield Cannons do not collide with one another

Update 5.85:

- Fixed the expire time for the Shield Cannon projectiles; it was 600 seconds for testing purposes, is now 20.

Update 5.84:

- Reworked the AI for the Flak Cannons, they should hopefully be autofiring correctly now.

- Heavily reduced the amount of projectiles for the Shield Cannons, to help with lag.

- Made Disruptor Cannons counter Shield Cannons.

- Reworked Implosion Cannons to be more effective.

- Reduced fire costs for the Shield Cannons.

- Fixed the reload animation sprites for the Heavy Shotgun, Implosion, Shield cannons.

- Made Shotgun Cannons, Implosion Cannons more effective against Shield Cannons.

Update 5.81:

- Halfed the projectiles made by the Shield Cannons for performance reasons. The projectile health has been doubled to compensate.

Update 5.8:

- Re-added the Shield Cannons

Shield Cannons create an arc of projectiles which sit in the air for a while and block projectiles. They are a purely defensive weapon.

Update 5.71:

- Fixed repair station bug
