v2.3.4
Stellaris 4.0 compatibility patch:
- Added bioship cost triggers and modifiers to defense platform sections and T slot weapons.
- Implemented logistics trade upkeep and role selector background for standard ship sizes and removed piracy suppression data.
- Implemented triggers that block bioship empires from getting mechanical ship weapons.
- Added missing weapon tags for slot size to mecanical ship weapons.
- Added cosmic storm AI weight factors.

Other changes:
- Added new logic for using archeo-tech weapons. Empires will only use them if they have more than 2000 minor artifacts stored and more than +2 minor artifacts income. Even then empires who don't have the Archaeo-Engineers perk will prefer normal weapons, unless they have more than 5000 minor artifacts stored and more than +5 minor artifacts income.
- Energy torpedoes are now classified as explosive weapons.

v2.2
Anti-lag update: AI will focus on building big ships unless it took the Armored in Firepower ascension perk. This leads to fewer ships in the galaxy, which reduces lag.
Details:
- After researching Destroyers technology the AI will stop building corvettes.
- After researching Cruisers technology the AI will stop building frigates.
- After researching Battleships technology the AI will stop building destroyers.
- After researching Battleships technology the AI will favor using P slots on smaller ships even if PD weapons are not the most advanced weapons available.
- Added new Picket Stern for cruisers.
- If AI has the Armored in Firepower ascension perk, it will continue to build destroyers even after researching Battleships technology.
- Armored in Firepower requirements changed from 1 other perk and Battleships technology to 2 other perks and Cruisers technology.
- AI is less likely to take Armored in Firepower.
- Fixed missing AI tags on weapons and ship sections. Ship designer will now recognize the various stealth roles.

Updated recommended game version.

v2.1
- Incorporated archaeotech weapons.
- Proton and Neutron Launchers now use the cost and upkeep for medium weapons instead of the cost and upkeep for large weapons.
- Large railguns and plasma no longer have a minimum range.
- All X and T size weapons now have 45 minimum range.

v2.0
- Remade mod from scratch for the 3.6 Orion patch.
- In addition to more intelligently choosing ship sections the AI will now also more intelligently choose which weapons to put in each slot size.
- The downside of the above is a higher risk of mod conflict, but it should be compatible with most popular mods.
- Added various AI tags to ship sections and weapons to make the role selector in the ship designer more intelligent.
- Most of the new ship sections added by previous versions of the mod are gone.
- Modified standard ship sections: Destroyer Picket Bow (SSP -> MPP), Cruiser Hangar Core (PPH -> SSH), Cruiser Torpedo Core (SSGG -> GGG), Battleship Hangar Bow (HMPP -> HMSS), Battleship Carrier Core (SSPPHH -> SSSSHH)
- New standard ship sections: Multirole Frigate (PG), Destroyer Interceptor Ship Bow (SSS + extra defenses), Destroyer Torpedo Stern (G), Multirole Menacing Cruiser (LGMSP)
- Retained Armored in Firepower ascension perk, though it now provides different new sections than before: Guardian Corvette (MPP), Gunstar Corvette (MM), Guardian Frigate (GPP), Nova Frigate (GG), Destroyer Gunstar Stern (MM), Destroyer Nova Stern (GG).
- Standard Frigates and standard destroyer stern get +2 small slots for defenses (so a standard destroyer has 8 small slots for defenses total).
