Bump version after stablizing with niv

There was a hash mismatch between the build artifact and the release .8xp. Assuming that the assembler is deterministic (I haven't checked), the sha256sum should be 698543ffeea730058f7878626e3a9c660fb4f99da7e318c8486a49b391ea4332.

Previous release info

• REPL no longer prints OK verbosely
• Numbers no longer need to be preceded by the NUM word (i.e. 1234 3456 + . works as expected).
