- Updated the Japanese language translation files.

- Heavy bridges (stone or metal bridges which can support heavy construction) can now only be built once "Advanced Bridge Building" has been researched. Basic wooden bridges can still be built from the very beginning of a game.

- Squashed the bug that was causing floors under boardwalks to disappear when a game was reloaded. Sadly, this doesn't fix tiles already affected by the bug.

- Also squashed a bug that was allowing floors to be built over mud (or under bridges) if this mod was being used in conjunction with Fluffy's "Stuffed Floors."

- Since bridges and boardwalks can't be destroyed, they no longer burn at all. (Yeah, I should have thought to make that change a month ago.)

- Improved the "under boardwalk" terrain distinctions.

- Boardwalks built over non-vanilla terrains will now provide pawns with a 100% walk speed.

- The mod is now compatible with "Nature's Pretty Sweet." Most notably, it's now possible to build boardwalks over salt fields or wet sand.

- The mod now also works the the "Mod Sync Ninja" updater.

- Bridges and boardwalks no longer have hit points. On the one hand, this means wooden bridges are unrealistically immune to fire. On the other hand, it means bridges and boardwalks are no longer "raider magnets" undermining raid AI.

- Bridges are now placeable in two dimensions, to make construction of large bridges a bit easier.

- Boardwalks can now once again be constructed over floors, or floors under boardwalks, in order to allow cleaner transition lines between the two.

- Fixed a bug that was screwing up terrain under bridges when games were saved and reloaded, which led to oddities when bridges were deconstructed.

- Deconstructing a bridge on a snowy map will no longer leave snow sitting on top of the water.

- Walk speed on bridges and boardwalks is now 100%. (This change doesn't impact bridges or boardwalks built before the change was implemented.)

- To cover mud tiles, you should now build boardwalks rather than bridges. (This change doesn't impact bridges already built over mud.)

- Boardwalks placed over marshy soil will now support heavy construction, as they ought to. (Repeat after me: This change doesn't impact boardwalks already constructed before the change was implemented.)

- Boardwalks, unlike bridges, are now placeable in two dimensions instead of just one.

- Boardwalks can no longer be placed over floors or over other boardwalks.

- It is now possible to build boardwalks over marshy terrain even if no water is nearby.

- Added Chinese language translation files provided by kghostSATORI.
