- Feature: Translations of baseset descriptions via language files (r25209, r25205)
- Fix: The level crossing sound is an ambient sound and not a new year sound (r25200)
- Fix: Refactor Script Debug GUI to only set widget states in OnInvalidateData [FS#5490] (r25052)

- Fix: Minimise gaps feature caused removal to only happen at the signal build interval instead of the implicit interval of 1 [FS#5479] (r25038)
- Fix: Green path signals would be shown when building them 'under' a train, and they would keep showing green until they were passed again [FS#5480] (r25037)
