This version is guaranteed to contain serious bugs, and the publically
visible interfaces will almost certainly change before 1.8 is
released. The 1.7 releases might be termed "selected snapshots".
Specifically, libguile has not yet been reviewed for thread-safeness.
We are releasing it anyway to start testing the new features, and to
get feedback about how well Guile actually behaves in a multi-threaded
setting.
The shared library major versions have been bumped compared to the 1.6
series, but they will not be bumped on binary incompatible changes
within the 1.7 series.
We already know about some issues with 1.8.0, please check the mailing
lists:

* The low-level thread API has been removed.
* There is now support for copy-on-write substrings and
mutation-sharing substrings.
* A new family of functions for converting between C values and
Scheme values has been added that is future-proof and thread-safe.
* The INUM macros like SCM_MAKINUM have been deprecated.
* The macros SCM_STRINGP, SCM_STRING_CHARS, SCM_STRING_LENGTH,
SCM_SYMBOL_CHARS, and SCM_SYMBOL_LENGTH have been deprecated.
* There is a new way to deal with non-local exits and re-entries in
C code, which is nicer than scm_internal_dynamic_wind.
* There are new malloc-like functions that work better than
scm_must_malloc, etc.
* There is a new way to access all kinds of vectors and arrays from
C that is efficient and thread-safe.
