+Changes in 2.0.8 (since 2.0.7):
+
+* TODO
+
+Reorder points in order of importance and make comprehensible
+
+Assemble thanks
+
+* Notable changes
+
+** New guile.m4.
+
+The `guile.m4' autoconf macros have been rewritten to use `guild' and
+`pkg-config' instead of the deprecated `guile-config' (which itself
+calls pkg-config).
+
+There is also a new macro, `GUILE_PKG', which allows packages to select
+the version of Guile that they want to compile against. See "Autoconf
+Macros" in the manual, for more information.
+
+** Better Windows support.
+
+Guile now correctly identifies absolute paths on Windows (MinGW), and
+creates files on that platform according to its path conventions. See
+XXX in the manual, for all details.
+
+In addition, the new Gnulib imports provide `select' and `poll' on
+Windows builds.
+
+As an incompatible change, systems that are missing <sys/select.h> were
+previously provided a public `scm_std_select' C function that defined a
+version of `select', but unhappily it also provided its own incompatible
+definitions for FD_SET, FD_ZERO, and other system interface. Guile
+should not be setting these macros in public API, so this interface was
+removed on those plaforms (basically only MinGW).
+
+** Gnulib update.
+
+Guile's copy of Gnulib was updated to v0.0-7865-ga828bb2. The following
+modules were imported from Gnulib: select, times, pipe-posix, fstat,
+getlogin, and poll.
+
+** New optimizations.
+
+There were a number of improvements to the partial evaluator, allowing
+complete reduction of forms such as:
+
+ ((let ((_ 10)) (lambda () _)))
+
+ ((lambda _ _))
+
+ (apply (lambda _ _) 1 2 3 '(4))
+
+ (call-with-values (lambda () (values 1 2)) (lambda _ _))
+
+A number (ahem) of numeric operations on have been made faster, among
+them GCD and logarithms.
+
+Finally, `array-ref', `array-set!' on arrays of rank 1 or 2 is now
+faster, because it avoids building a rest list. Similarly, the
+one-argument case of `array-for-each' and `array-map!' has been
+optimized, and `array-copy!' and `array-fill!' are faster.
+
+** `include' resolves relative file names relative to including file.
+
+Given a relative file name, `include' will look for it relative to the
+directory of the including file. This harmonizes the behavior of
+`include' with that of `load'.
+
+** SLIB compatibility restored.
+
+Guile 2.0.8 is now compatible with SLIB. You will have to use a
+development version of SLIB, however, until a new version of SLIB is
+released.
+
+** Better ,trace REPL command.
+
+Sometimes the ,trace output for nested function calls could overflow the
+terminal width, which wasn't useful. Now there is a limit to the amount
+of space the prefix will take. See the documentation for ",trace" for
+more information.
+
+** Update predefined character sets to Unicode 6.2.
+
+** GMP 4.2 or later required
+
+Guile used to require GMP at least version 4.1 (released in May 2002),
+and now requires at least version 4.2 (released in March 2006).
+
+* Manual updates
+
+** Better SXML documentation.
+
+The documentation for SXML modules was much improved, though there is
+still far to go. See "SXML" in manual.
+
+** Style updates.
+
+Use of "iff" was replaced with standard English. Keyword arguments are
+now documented consistently, along with their default values.
+
+** An end to the generated-documentation experiment.
+
+When Guile 2.0 imported some modules from Guile-Lib, they came with a
+system that generated documentation from docstrings and module
+commentaries. This produced terrible documentation. We finally bit the
+bullet and incorporated these modules into the main text, and will be
+improving them manually over time, as is the case with SXML. Help is
+appreciated.
+
+** New documentation.
+
+There is now documentation for `scm_array_type', and `scm_array_ref', as
+well as for the new `array-length' / 'scm_c_array_length' /
+`scm_array_length' functions. `array-in-bounds?' has better
+documentation as well. The `program-arguments-alist' and
+`program-lambda-list' functions are now documented. Finally, the GOOPS
+class hierarchy diagram has been regenerated for the web and print
+output formats.
+
+* New deprecations
+
+** Deprecate generalized vector interface.
+
+The generalized vector interface, introduced in 1.8.0, is simply a
+redundant, verbose interface to arrays of rank 1. `array-ref' and
+similar functions are entirely sufficient. Thus,
+`scm_generalized_vector_p', `scm_generalized_vector_length',
+`scm_generalized_vector_ref', `scm_generalized_vector_set_x', and
+`scm_generalized_vector_to_list' are now deprecated.
+
+** Deprecate SCM_CHAR_CODE_LIMIT and char-code-limit.
+
+These constants were defined to 256, which is not the highest codepoint
+supported by Guile. Given that they were useless and incorrect, they
+have been deprecated.
+
+** Deprecate `http-get*'.
+
+The new `#:streaming?' argument to `http-get' subsumes the functionality
+of `http-get*' (introduced in 2.0.7). Also, the `#:extra-headers'
+argument is deprecated in favor of `#:headers'.
+
+** Deprecate (ice-9 mapping).
+
+This module, present in Guile since 1996 but never used or documented,
+has never worked in Guile 2.0. It has now been deprecated and will be
+removed in Guile 2.2.
+
+** Deprecate undocumented array-related C functions.
+
+These are `scm_array_fill_int', `scm_ra_eqp', `scm_ra_lessp',
+`scm_ra_leqp', `scm_ra_grp', `scm_ra_greqp', `scm_ra_sum',
+`scm_ra_product', `scm_ra_difference', `scm_ra_divide', and
+`scm_array_identity'.
+
+
+* New interfaces
+
+** `round-ash', a bit-shifting operator that rounds on right-shift.
+
+See "Bitwise Operations".
+
+** New environment variables: `GUILE_STACK_SIZE', `GUILE_INSTALL_LOCALE'.
+
+See "Environment Variables".
+
+** New procedure `sendfile'.
+
+See "File System".
+
+** New procedures for dealing with file names.
+
+See "File System" for documentation on `system-file-name-convention',
+`file-name-separator?', `absolute-file-name?', and
+`file-name-separator-string'.
+
+** Escape continuations with `call/ec' and `let/ec'
+
+See "Prompt Primitives".
+
+** `array-length', an array's first dimension.
+
+See "Array Procedures".
+
+** `hash-count', for hash tables.
+
+See "Hash Tables".
+
+** New foreign types: `ssize_t', `ptrdiff_t'.
+
+See "Foreign Types".
+
+** New C helpers: `scm_from_ptrdiff_t', `scm_to_ptrdiff_t'.
+
+See "Integers".
+
+** Much more capable `xml->sxml'
+
+See "Reading and Writing XML" for information on how the `xml->sxml'
+parser deals with namespaces, processed entities, doctypes, and literal
+strings. Incidentally, `current-ssax-error-port' is now a parameter
+object.
+
+** New command-line argument: `--language'.
+
+See "Command-line Options" in the manual.
+
+** `current-language' in default environment.
+
+Previously defined only in `(system base language)', `current-language'
+is now defined in the default environment, and is used to determine the
+language for the REPL, and for `compile-and-load'.
+
+** New procedure: `fluid->parameter'
+
+See "Parameters", for information on how to convert a fluid to a
+parameter.
+
+** New procedures to read all characters from a port
+
+See "Line/Delimited" in the manual for documentation on `read-string'
+ and `read-string!'.
+
+** New HTTP client procedures.
+
+See "Web Client" for documentation on the new `http-head', `http-post',
+`http-put', `http-delete', `http-trace', and `http-options' procedures,
+and also for more options to `http-get'.
+
+** New procedures for converting strings to and from bytevectors.
+
+See "Representing Strings as Bytes" for documention on the new `(ice-9
+iconv)' module and its `bytevector->string' and `string->bytevector'
+procedures.
+
+** New `print' REPL option.
+
+See "REPL Commands" in the manual for information on the new
+user-customizable REPL printer.
+
+** New variable: %site-ccache-dir.
+
+The "Installing Site Packages" and "Build Config" manual sections now
+refer to this variable to describe where users should install their
+`.go' files.

Changes in 2.0.7 (since 2.0.6):
* Notable changes
made possible by the use of delimited continuations (see the manual for
details.)
-Consequently, `par-map' has been rewritten and can now use all cores.
+Consequently, `par-map' and `par-for-each' have been rewritten and can
+now use all cores.
+
+** `GUILE_LOAD_PATH' et al can now add directories to the end of the path
+
+`GUILE_LOAD_PATH' and `GUILE_LOAD_COMPILED_PATH' can now be used to add
+directories to both ends of the load path. If the special path
+component `...' (ellipsis) is present in these environment variables,
+then the default path is put in place of the ellipsis, otherwise the
+default path is placed at the end. See "Environment Variables" in the
+manual for details.
** `load-in-vicinity' search for `.go' files in `%load-compiled-path'
The `string-split' procedure can now be given a SRFI-14 character set or
a predicate, instead of just a character.
-** R6RS SRFI support --- FIXME
+** R6RS SRFI support
-5d7c55b R6RS srfi library names should ignore first identifier after the :n
-acc1d8e Preserve additional R6RS library name components after srfi :n
+Previously, in R6RS modules, Guile incorrectly ignored components of
+SRFI module names after the SRFI number, making it impossible to specify
+sub-libraries. This release corrects this, bringing us into accordance
+with SRFI 97.
** `define-public' is no a longer curried definition by default
