    Gauche 0.8.8: Major maintenance release
      + Important Changes:
          o Exact rational number is supported; now you get 1/3 from (/ 1 3).
            To obtain inexact number from division of two exact numbers, you
            have to use exact->inexact explicitly. With this change you can get
            more exact result, but if your code has relied on the old Gauche
            behavior that automatically converts rationals to inexact reals,
            your code may run very slowly in this release of Gauche (since
            exact rational arithmetic is much slower than flonum arithmetic).
            For the smooth transition, a compatibility module compat.norational
            is provided, which makes the / operator behaves like before. See
            the manual entry for the details.
          o The reader is more strict about utf-8 encoding. Consequently, some
            source files in other encoding that happened to be accepted by
            previous versions of Gauche may no longer work. If you get an
            error, either convert the encoding of the source, or use "coding:"
            magic comment (See "Multibyte scripts" section of the reference
            manual).
          o The test-module routine in gauche.test is fixed so that it detects
            more references to undefined global variables that have been
            overlooked. You may get an error something like "symbols referenced
            but not defined: ...". In most cases, they are from typos. See the
            manual entry of gauche.test - Unit testing for the details.
          o New modules:
              # sxml.serializer: Generic routine to convert SXML to other
                formats like XML or HTML. Written by Dmitry Lizorkin and ported
                to Gauche by Leonardo Boiko.
              # util.trie: Implementation of Trie. Originally by OOHASHI
                Daichi, and hacked by numerous Gauche hackers.
              # util.rbtree: Implementation of Red-Black Tree. Written by Rui
                Ueyama.
          o A bug in port locking routine, that caused a race condition on
            multiprocessor machine, is fixed. As a side effect, port lock
            operation became a bit faster.
          o C API prospected change: Scm_Eval, Scm_EvalCString, and Scm_Apply
            will have different API in the next release. The current API is
            kept under a different name, Scm_EvalRec, Scm_EvalCStringRec, and
            Scm_ApplyRec. If you are using those functions, please make changes
            until the next release.
