The NEWS file is quite long. Here are the most interesting entries:
Changes since 1.6:
* Guile is now licensed with the GNU Lesser General Public License.
* The manual is now licensed with the GNU Free Documentation License.
* We now use GNU MP for bignums.
* We now have exact rationals, such as 1/3.
* We now use native POSIX threads for real concurrent threads.
* There is a new way to initalize Guile that allows one to use Guile
from threads that have not been created by Guile.
* Mutexes and condition variables are now always fair. A recursive
mutex must be requested explicitly.
* 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.
* The concept of dynamic roots has been factored into continuation
barriers and dynamic states.
See NEWS and the manual for more details.
