Due to Murphy's law, I introduced an important bug at the very end of my tests, just before releasing Solarus 1.0.2. This bug made you fail to push blocks completely (the last pixel of the movement was not done). So here is a new patch release (1.0.3) that just fixes this bug. You really want to upgrade.
There are no changes in our games (ZSDX and ZSXD) but they get a new version number (1.6.1) because on some systems, the engine is included with the game.
(I really should make unit tests one day!)
