* New modules (see the manual for details)
+** `(srfi srfi-18)', multithreading support
** The `(ice-9 i18n)' module provides internationalization support
* Changes to the distribution
* Changes to the C interface
+** The GH interface (deprecated in version 1.6, 2001) was removed.
+
+** Internal `scm_i_' functions now have "hidden" linkage with GCC/ELF
+
+This makes these internal functions technically not callable from
+application code.
+
** Functions for handling `scm_option' now no longer require an argument
indicating length of the `scm_t_option' array.

Changes in 1.8.6 (since 1.8.5)
-* Bugs fixed
+* New features (see the manual for details)
-** Internal `scm_i_' functions now have "hidden" linkage with GCC/ELF
+** New convenience function `scm_c_symbol_length ()'
-This makes these internal functions technically not callable from
-application code.
+** Single stepping through code from Emacs
+
+When you use GDS to evaluate Scheme code from Emacs, you can now use
+`C-u' to indicate that you want to single step through that code. See
+`Evaluating Scheme Code' in the manual for more details.
+
+** New "guile(1)" man page!
+
+* Changes to the distribution
+
+** Automake's `AM_MAINTAINER_MODE' is no longer used
+
+Thus, the `--enable-maintainer-mode' configure option is no longer
+available: Guile is now always configured in "maintainer mode".
+
+* Bugs fixed
+
+** `symbol->string' now returns a read-only string, as per R5RS
+** Fix incorrect handling of the FLAGS argument of `fold-matches'
+** `guile-config link' now prints `-L$libdir' before `-lguile'
+** Fix memory corruption involving GOOPS' `class-redefinition'
+** Fix possible deadlock in `mutex-lock'
+** Fix build issue on Tru64 and ia64-hp-hpux11.23 (`SCM_UNPACK' macro)
+** Fix build issue on mips, mipsel, powerpc and ia64 (stack direction)
+** Fix build issue on hppa2.0w-hp-hpux11.11 (`dirent64' and `readdir64_r')
+** Fix build issue on i386-unknown-freebsd7.0 ("break strict-aliasing rules")
+** Fix misleading output from `(help rationalize)'
+** Fix build failure on Debian hppa architecture (bad stack growth detection)
+** Fix `gcd' when called with a single, negative argument.
+** Fix `Stack overflow' errors seen when building on some platforms
