FIRS 4.8.0 is not savegame-compatible with any previous version of FIRS.
Changes
- reworked Electric Arc Furnace
- entirely new sprites
- new larger layouts using 'outpost' approach
- tweaked fences at Basic Oxygen Furnace so that the casting line is always fenced, even if a station is adjacent
- added ECS Basic Vector II to list of incompatible grfs
- removed pink scaffolding pixels from Basic Oxygen Furnace, as they are hidden with original baseset, but show up with OpenGFX
- note in docs that since OpenTTD 12.0, FIRS is supported by default vehicles
- translation updates (thanks translators)
