v0.8

CHANGES:

• Implementation of RFC1951 (task from @cfcs)

• breaking change New interface of decompress

  We wrap API in Zlib_{inflate/deflate} and add RFC1951_{inflate/deflate}.

• Move to jbuilder/dune (task from @samoht)

• Better check on zlib header

• Fixed infinite loop (task fron @cfcs)

  See 2e3af68, decompress has an infinite loop when the inflated dictionary
  does not provide any bindings (and length of opcode is <= 0). In this case,
  decompress expects an empty input and provide an empty output in any case.

• Use re.1.7.2 on tests

• Use camlzip.1.07 on tests
