Previously they would use the `off_t' type, which is fragile since its
definition depends on the application's value for `_FILE_OFFSET_BITS'.
+** Automatically compiled files will be placed in ~/.cache, not ~/.guile-ccache.
+
+Actually, they will be placed in $XDG_CACHE_HOME/guile/ccache/1.9,
+defaulting to XDG_CACHE_HOME=~/.cache. Users may remove their
+~/.guile-ccache directories.
+
+** New language: Brainfuck.
+
+Brainfuck is a toy language that closely models Turing machines. Guile's
+brainfuck compiler is meant to be an example of implementing other
+languages. See the manual for details, or
+http://en.wikipedia.org/wiki/Brainfuck for more information about the
+Brainfuck language itself.
+
+** A number of Scheme files were corrected to be LGPLv3+.
+
+Some Scheme files imported for the compiler were erroneously labeled as
+being LGPLv2+ or GPLv2+. This oversight has been fixed.
+
+** Bytevectors may now be accessed with a C-friendly API.
+
+New functions: `scm_is_bytevector ()', `scm_c_bytevector_length ()',
+`scm_c_bytevector_length ()', and `scm_c_bytevector_set_x ()'. See the
+manual for details.
+
+** Bytevectors are now accessible using the generalized-vector API.
+
+As a side effect, this change allows compilation of literal bytevectors
+(`#vu8(...)').
+
+** Meta-commands to the REPL work better with strange languages.
+
+Specifically, meta-commands that take expressions as arguments will use
+the current language's reader to read those expressions, which may span
+multiple lines, with readline integration if the user has that enabled.
+
+** The object code file format has changed.
+
+The objcode loader will complain about a "bad header cookie" if it
+happens to find an old file. The workaround for that is currently to
+find all stale .go files and remove them. This is likely to affect users
+who have checked out Guile's git repository, not those that build from
+tarballs.
+
+** Vector access has been sped up considerably.
+
+Guile's virtual machine now has vector and bytevector operations. Using
+Guile to process large amounts of data is now easier. This is because
+`vector-ref' and `vector-set!' now have fast opcodes. In addition, there
+are opcodes for `ref' and `set' operations on bytevectors for everything
+from 8-bit integers to 64-bit floating-point values.
+
+In the next release, we hope to extend this speedup to other kinds of
+uniform vectors.
+
+** The `long_long' C type, deprecated in 1.8, has been removed.
+
+** And of course, the usual collection of bugfixes.
+
+Interested users should see the ChangeLog for more information.

Changes in 1.9.x (since the 1.8.x series):
* New modules (see the manual for details)
installation, care should be taken to preserve their original
timestamps.
-Autocompiled files will be stored in the user's ~/.guile-ccache
-directory, which will be created if needed. This is analogous to
-ccache's behavior for C files.
+Autocompiled files will be stored in the $XDG_CACHE_HOME/guile/ccache
+directory, where $XDG_CACHE_HOME defaults to ~/.cache. This directory
+will be created if needed.
To inhibit autocompilation, set the GUILE_AUTO_COMPILE environment
variable to 0, or pass --no-autocompile on the Guile command line.
but not all of the libraries are there yet. This support is not yet
documented; ask on the mailing list if you are interested.
