 * "(15:45:28) notch will we be able to use water as block? [...] (15:45:35) in build mode? [...] (15:46:45) <@Notch> taodih: I already can in 0.0.14, but it's DANGEROUS"

Offset test (May 25, 2009)
Word of Notch post, YouTube video (reupload)
 * General
 * Online level saving re-enabled.
 * Blocks
 * Vertex and colour offset tests
 * Vertex offsets cause "wavy" blocks, making the world look more realistic.
 * Colour offsets cause every block to be a slightly different colour.
 * Was later removed as Notch didn't like the idea.

Trivia

 * Respawning when pressing worked just like in 0.0.13a_03 and prior, as this was not changed until the public release of 0.0.14a.
 * The mouse features (auto breaking/building when left-click is held down, scroll-wheel block picking support and pick-block with middle mouse button) were all added on May 27, 2009 for the full release of 0.0.14a.
