This release reverts the upgrade from SDL2 to SDL3. SDL3 had too many bugs to be usable - R/B channel color swaps, overly bright windows, broken scaling, crashing on wayland, etc.

These issues should now be fixed again. This also means that the fullscreen/borderless window options have been returned to their pre-155 state.

Other patch notes:

• Fixed multiplayer not working on Steam - both the host and the client will need to update to connect properly
• Fixed core database search being broken
• Fixed cyanogen synthesizer using less graphite than expected
• Fixed cross-planet launches being possible in specific scenarios
• Fixed double-clicking a sector bypassing launch checks
• Fixed more bugs with bullet collision logic
• Minor adjustments to salvo copper ammo
• 32-bit Windows builds now display an error when launching, and will be discontinued in the future entirely

• Fixed scrolling not rotating blocks/schematics on certain systems
• Fixed R and B channels of game window being swapped on some systems
• Fixed certain bullets not triggering their despawn actions
• Fixed directional shields forcing units to "stick" to them
• Fixed mods with incorrect content initialization code crashing the core database

• Fixed Precept dealing 10 damage instead of 120
• Fixed hitscan line projectiles not spawning effects/fire/etc at hit position

• Changed missile explosion visuals based on whether they exploded on a target or were shot down
• On desktop, the 'fullscreen' option now uses borderless fullscreen; the separate 'borderless fullscreen' option has been removed
• Potentially fixed the screen getting bright in fullscreen on desktop (this may need to be fixed upstream in SDL 3.4.x)

• Made flying units in waves ignore empty/inactive blocks when finding a target

• Made Interplanetary Accelerator accept resources to launch with
• Moved Cruxscape and Geothermal Stronghold off of the tech tree
• Made loadout schematics get built upon landing on Serpulo, matching Erekir
• Renamed Sea Port map submission

• Reverted Flare silicon cost increase, but added silicon to the block build cost
• Made mods skip texture packing if no new textures are present
• Added a 'iosCompatible' flag for script mods that work on iOS (experimental)
• Added a logic unit command for deconstruction; this is disabled by default in the rules

Note: 154.1 was skipped, as that version only had some internal deployment fixes for Android/iOS that did not affect other platforms.

• Nerfed Flare damage and range significantly
• Increased liquid capacity of many blocks based on consumption rate
• Fixed a possible crash
• Increased Java mod minGameVersion due to new sound effect name changes
• Removed some unnecessary debug logging during map loads

This release includes a complete sound rework for most units and blocks, with a focus on Serpulo content. The audio engine has also been improved to handle more simultaneous sounds without cutting off playback.

Full changelog:

• Made Beta's guns no longer rotate
• Improved Scepter's secondary weapon visuals and damage (Contributed by @EggleEgg)
• Made Ripple fire half as frequently with ~2x the damage per shot
• Removed Flare spawners from Omura (they were annoying and useless for its tech tier)
• New Flare attack patterns and AI, with a return to older v5 circling behavior - surprisingly, about 85% of the community voted to approve this change in the Discord
• Increased shale's oil production attribute value
• Reduced research costs for higher tier units on Serpulo
• Removed the background wave simulation system - sectors with waves that are not being played on will be frozen in time, and will not produce items
• Disabled Serpulo sector invasions by default - this system will likely be removed or reworked entirely in the future
• Enabled core incineration by default
• Increased active sound cap (32 -> 100)
• Limited sounds to a maximum of ~6 per type (one sound can't drown out all the others)
• Complete rework of most sounds in the game, with a focus on Serpulo units and turrets
• Added a large amount of new sounds to blocks/units/functions that were lacking them
• Added movement sounds for most units
• Renamed most sound effects - while this will break mods and logic, it was necessary, as the old sound naming scheme was an incomprehensible mess
• Fixed the game disabling other audio sources on startup on iOS
• Many minor bugfixes, crash fixes and improvements for the data patch system
• Fixed logic insert line button not working properly
• Fixed the window not being sized to the screen in some cases on iOS
• Fixed Intel GPUs not being detected properly on Windows

The highlight of this release is a new system for patching stats of content on servers and maps. This system will allow players to customize health, requirements, recipes, weapons, bullets, etc. individually. This is not a replacement for modding, as it does not allow adding new assets or content, but it does allow making major changes to the way the game is played and balanced.
