* raco now supports an experimental "demodularizer" that collapses a module's dependencies into a new module comprising the whole program. This currently provides no performance improvement, but will be the basis for providing cross-module optimization and dead-code elimination. It is currently useful, however, for static analysis of whole Racket programs. > > Mike: > fa854f62fc22a81cbb3aa0efa1997ade18c9e7c3 > Add vector signatures, and `vector-of' to the HtDP signature syntax. > > Vincent: > 4ac36fd59bc35cb0d60cb050cfaae21d213064c8 > Added the new single-precision float function to TR. > ac76d963b0e4b70c17753b22833c630f3d71cd1b > Enable single-precision floats by default. > 46f086282d7302e7e015109c9f945a92350e384c > Bytes are a sequence of the new Byte type. > d4c93cc12e6df893ba2e782f0e0ea5529738315a > TR's numeric tower is now built from unions of non-overlapping base > types. > > A lot of the work that was done by special-casing number types can > now be > done by TR's handling of unions.
