+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.

+\f
+Changes in 2.0.7 (since 2.0.6):
+
+* Notable changes
+
+** SRFI-105 curly infix expressions are supported
+
+Curly infix expressions as described at
+http://srfi.schemers.org/srfi-105/srfi-105.html are now supported by
+Guile's reader. This allows users to write things like {a * {b + c}}
+instead of (* a (+ b c)). SRFI-105 support is enabled by using the
+`#!curly-infix' directive in source code, or the `curly-infix' reader
+option. See the manual for details.
+
+** Reader options may now be per-port
+
+Historically, `read-options' and related procedures would manipulate
+global options, affecting the `read' procedure for all threads, and all
+current uses of `read'.
+
+Guile can now associate `read' options with specific ports, allowing
+different ports to use different options. For instance, the
+`#!fold-case' and `#!no-fold-case' reader directives have been
+implemented, and their effect is to modify the current read options of
+the current port only; similarly for `#!curly-infix'. Thus, it is
+possible, for instance, to have one port reading case-sensitive code,
+while another port reads case-insensitive code.
+
+** Futures may now be nested
+
+Futures may now be nested: a future can itself spawn and then `touch'
+other futures. In addition, any thread that touches a future that has
+not completed now processes other futures while waiting for the touched
+future to completed. This allows all threads to be kept busy, and was
+made possible by the use of delimited continuations (see the manual for
+details.)
+
+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'
+
+Previously, `load-in-vicinity' would look for compiled files in the
+auto-compilation cache, but not in `%load-compiled-path'. This is now
+fixed. This affects `load', and the `-l' command-line flag. See
+<http://bugs.gnu.org/12519> for details.
+
+** Extension search order fixed, and LD_LIBRARY_PATH preserved
+
+Up to 2.0.6, Guile would modify the `LD_LIBRARY_PATH' environment
+variable (or whichever is relevant for the host OS) to insert its own
+default extension directories in the search path (using GNU libltdl
+facilities was not possible here.) This approach was problematic in two
+ways.
+
+First, the `LD_LIBRARY_PATH' modification would be visible to
+sub-processes, and would also affect future calls to `dlopen', which
+could lead to subtle bugs in the application or sub-processes. Second,
+when the installation prefix is /usr, the `LD_LIBRARY_PATH' modification
+would typically end up inserting /usr/lib before /usr/local/lib in the
+search path, which is often the opposite of system-wide settings such as
+`ld.so.conf'.
+
+Both issues have now been fixed.
+
+** `make-vtable-vtable' is now deprecated
+
+Programs should instead use `make-vtable' and `<standard-vtable>'.
+
+** The `-Wduplicate-case-datum' and `-Wbad-case-datum' are enabled
+
+These recently introduced warnings have been documented and are now
+enabled by default when auto-compiling.
+
+** Optimize calls to `equal?' or `eqv?' with a constant argument
+
+The compiler simplifies calls to `equal?' or `eqv?' with a constant
+argument to use `eq?' instead, when applicable.
+
+* Manual updates
+
+** SRFI-9 records now documented under "Compound Data Types"
+
+The documentation of SRFI-9 record types has been moved in the "Compound
+Data Types", next to Guile's other record APIs. A new section
+introduces the various record APIs, and describes the trade-offs they
+make. These changes were made in an attempt to better guide users
+through the maze of records API, and to recommend SRFI-9 as the main
+API.
+
+The documentation of Guile's raw `struct' API has also been improved.
+
+** (ice-9 and-let-star) and (ice-9 curried-definitions) now documented
+
+These modules were missing from the manual.
+
+* New interfaces
+
+** New "functional record setters" as a GNU extension of SRFI-9
+
+The (srfi srfi-9 gnu) module now provides three new macros to deal with
+"updates" of immutable records: `define-immutable-record-type',
+`set-field', and `set-fields'.
+
+The first one allows record type "functional setters" to be defined;
+such setters keep the record unchanged, and instead return a new record
+with only one different field. The remaining macros provide the same
+functionality, and also optimize updates of multiple or nested fields.
+See the manual for details.
+
+** web: New `http-get*', `response-body-port', and `text-content-type?'
+ procedures
+
+These procedures return a port from which to read the response's body.
+Unlike `http-get' and `read-response-body', they allow the body to be
+processed incrementally instead of being stored entirely in memory.
+
+The `text-content-type?' predicate allows users to determine whether the
+content type of a response is textual.
+
+See the manual for details.
+
+** `string-split' accepts character sets and predicates
+
+The `string-split' procedure can now be given a SRFI-14 character set or
+a predicate, instead of just a character.
+
+** R6RS SRFI support
+
+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
+
+The (ice-9 curried-definitions) should be used for such uses. See the
+manual for details.
+
+* Build fixes
+
+** Remove reference to `scm_init_popen' when `fork' is unavailable
+
+This fixes a MinGW build issue (http://bugs.gnu.org/12477).
+
+** Fix race between installing `guild' and the `guile-tools' symlink
+
+* Bug fixes
+
+** Procedures returned by `eval' now have docstrings
+ (http://bugs.gnu.org/12173)
+** web client: correctly handle uri-query, etc. in relative URI headers
+ (http://bugs.gnu.org/12827)
+** Fix docs for R6RS `hashtable-copy'
+** R6RS `string-for-each' now accepts multiple string arguments
+** Fix out-of-range error in the compiler's CSE pass
+ (http://bugs.gnu.org/12883)
+** Add missing R6RS `open-file-input/output-port' procedure
+** Futures: Avoid creating the worker pool more than once
+** Fix invalid assertion about mutex ownership in threads.c
+ (http://bugs.gnu.org/12719)
+** Have `SCM_NUM2FLOAT' and `SCM_NUM2DOUBLE' use `scm_to_double'
+** The `scandir' procedure now uses `lstat' instead of `stat'
+** Fix `generalized-vector->list' indexing bug with shared arrays
+ (http://bugs.gnu.org/12465)
+** web: Change `http-get' to try all the addresses for the given URI
+** Implement `hash' for structs
+ (http://lists.gnu.org/archive/html/guile-devel/2012-10/msg00031.html)
+** `read' now adds source properties for data types beyond pairs
+** Improve error reporting in `append!'
+** In fold-matches, set regexp/notbol unless matching string start
+** Don't stat(2) and access(2) the .go location before using it
+** SRFI-19: use zero padding for hours in ISO 8601 format, not blanks
+** web: Fix uri-encoding for strings with no unreserved chars, and octets 0-15
+** More robust texinfo alias handling
+** Optimize `format' and `simple-format'
+ (http://bugs.gnu.org/12033)
+** Angle of -0.0 is pi, not zero
+
+\f
+Changes in 2.0.6 (since 2.0.5):
+
+* Notable changes
+
+** New optimization pass: common subexpression elimination (CSE)
+
+Guile's optimizer will now run a CSE pass after partial evaluation.
+This pass propagates static information about branches taken, bound
+lexicals, and effects from an expression's dominators. It can replace
+common subexpressions with their boolean values (potentially enabling
+dead code elimination), equivalent bound lexicals, or it can elide them
+entirely, depending on the context in which they are executed. This
+pass is especially useful in removing duplicate type checks, such as
+those produced by SRFI-9 record accessors.
+
+** Improvements to the partial evaluator
+
+Peval can now hoist tests that are common to both branches of a
+conditional into the test. This can help with long chains of
+conditionals, such as those generated by the `match' macro. Peval can
+now do simple beta-reductions of procedures with rest arguments. It
+also avoids residualizing degenerate lexical aliases, even when full
+inlining is not possible. Finally, peval now uses the effects analysis
+introduced for the CSE pass. More precise effects analysis allows peval
+to move more code.
+
+** Run finalizers asynchronously in asyncs
+
+Finalizers are now run asynchronously, via an async. See Asyncs in the
+manual. This allows Guile and user code to safely allocate memory while
+holding a mutex.
+
+** Update SRFI-14 character sets to Unicode 6.1
+
+Note that this update causes the Latin-1 characters `§' and `¶' to be
+reclassified as punctuation. They were previously considered to be part
+of `char-set:symbol'.
+
+** Better source information for datums
+
+When the `positions' reader option is on, as it is by default, Guile's
+reader will record source information for more kinds of datums.
+
+** Improved error and warning messages
+
+`syntax-violation' errors now prefer `subform' for source info, with
+`form' as fallback. Syntactic errors in `cond' and `case' now produce
+better errors. `case' can now warn on duplicate datums, or datums that
+cannot be usefully compared with `eqv?'. `-Warity-mismatch' now handles
+applicable structs. `-Wformat' is more robust in the presence of
+`gettext'. Finally, various exceptions thrown by the Web modules now
+define appropriate exception printers.
+
+** A few important bug fixes in the HTTP modules.
+
+Guile's web server framework now checks if an application returns a body
+where it is not permitted, for example in response to a HEAD request,
+and warn or truncate the response as appropriate. Bad requests now
+cause a 400 Bad Request response to be printed before closing the port.
+Finally, some date-printing and URL-parsing bugs were fixed.
+
+** Pretty-print improvements
+
+When Guile needs to pretty-print Tree-IL, it will try to reconstruct
+`cond', `or`, and other derived syntax forms from the primitive tree-IL
+forms. It also uses the original names instead of the fresh unique
+names, when it is unambiguous to do so. This can be seen in the output
+of REPL commands like `,optimize'.
+
+Also, the `pretty-print' procedure has a new keyword argument,
+`#:max-expr-width'.
+
+** Fix memory leak involving applicable SMOBs
+
+At some point in the 1.9.x series, Guile began leaking any applicable
+SMOB that was actually applied. (There was a weak-key map from SMOB to
+trampoline functions, where the value had a strong reference on the
+key.) This has been fixed. There was much rejoicing!
+
+** Support for HTTP/1.1 chunked transfer coding
+
+See "Transfer Codings" in the manual, for more.
+
+** Micro-optimizations
+
+A pile of micro-optimizations: the `string-trim' function when called
+with `char-set:whitespace'; the `(web http)' parsers; SMOB application;
+conversion of raw UTF-8 and UTF-32 data to and from SCM strings; vlists
+and vhashes; `read' when processing string literals.
+
+** Incompatible change to `scandir'
+
+As was the original intention, `scandir' now runs the `select?'
+procedure on all items, including subdirectories and the `.' and `..'
+entries. It receives the basename of the file in question instead of
+the full name. We apologize for this incompatible change to this
+function introduced in the 2.0.4 release.
+
+* Manual updates
+
+The manual has been made much more consistent in its naming conventions
+with regards to formal parameters of functions. Thanks to Bake Timmons.
+
+* New interfaces
+
+** New C function: `scm_to_pointer'
+** New C inline functions: `scm_new_smob', `scm_new_double_smob'
+** (ice-9 format): Add ~h specifier for localized number output.
+** (web response): New procedure: `response-must-not-include-body?'
+** New predicate: 'supports-source-properties?'
+** New C helpers: `scm_c_values', `scm_c_nvalues'
+** Newly public inline C function: `scm_unget_byte'
+** (language tree-il): New functions: `tree-il=?', `tree-il-hash'
+** New fluid: `%default-port-conversion-strategy'
+** New syntax: `=>' within `case'
+** (web http): `make-chunked-input-port', `make-chunked-output-port'
+** (web http): `declare-opaque-header!'
+
+Search the manual for these identifiers, for more information.
+
+* New deprecations
+
+** `close-io-port' deprecated
+
+Use `close-port'.
+
+** `scm_sym2var' deprecated
+
+In most cases, replace with `scm_lookup' or `scm_module_variable'. Use
+`scm_define' or `scm_module_ensure_local_variable' if the second
+argument is nonzero. See "Accessing Modules from C" in the manual, for
+full details.
+

* Notable changes
available on your platform, such as /dev/urandom. See "Random Number
Generation" in the manual, for more.
+** Warn about unsupported `simple-format' options.
+
+The `-Wformat' compilation option now reports unsupported format options
+passed to `simple-format'.

** Manual updates
Besides the sections already mentioned, the following manual sections
** Add deprecated shim for `scm_display_error' with stack as first argument.

** Allow overlapping regions to be passed to `bytevector-copy!'.
-** Avoid calling `u32_conv_from_encoding' on the null string.
** Better function prologue disassembly
** Compiler: fix miscompilation of (values foo ...) in some contexts.
** Compiler: fix serialization of #nil-terminated lists.
** Don't leak file descriptors when mmaping objcode.
** Empty substrings no longer reference the original stringbuf.

** FFI: Hold a weak reference to the procedure passed to `procedure->pointer'.
** FFI: Properly unpack small integer return values in closure call.
** Fix R6RS `fold-left' so the accumulator is the first argument.
-** Fix `validate-target' in (system base target).
** Fix bit-set*! bug from 2005.

-** Peval: fold (values FOO) to FOO in more cases
** Statistically unique marks and labels, for robust hygiene across sessions.
** Web: Allow URIs with empty authorities, like "file:///etc/hosts".
** `,language' at REPL sets the current-language fluid.
** `primitive-load' returns the value(s) of the last expression.
