The category "Construction" under Infrastructure has been split into three sub categories:
- Construction sites
- Developable areas: Greenfields and Brownfields.
Details and other changes to categories which were added recently:
- Construction sites: landuse=construction, highway=construction, building=construction, railway=construction and all items with a tag prefixed with 'construction:'.
- Proposals: landuse=proposed, highway=proposed, building=proposed, railway=proposed and all items with a tag prefixed with 'proposed:'.
- Developable areas: landuse=greenfield and landuse=brownfield.
- Public transport amenities: Now includes airports (although I'm considering creating a whole "Aeroways" category and move them there)
- Individual Traffic / Maxspeed: now include maxspeed=walk (cyan) and maxspeed=none (magenta).
