Here are the most interesting entries: - - The INUM macros like SCM_MAKINUM have been deprecated. + Changes since 1.7.1: - - 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 initalize Guile that allows one to use Guile + from threads that have not been created by Guile. - - 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. + * Mutexes and condition variables are now always fair. A recursive + mutex must be requested explicitely. - - There are new malloc-like functions that work better than - scm_must_malloc, etc. + * The low-level thread API has been removed. -and most importantly + * There is a new way to access all kinds of vectors and arrays from + C that is efficient and thread-safe. - - call-with-current-continuation is now also available under the name - call/cc. + * The concept of dynamic roots has been factored into continuation + barriers and dynamic states.
