*** Dependencies
Guile 2.0.12 needs libunistring >= 0.9.3
This check is now part of the configure step.

*** FFI: Add support for functions that set 'errno'
** FFI: Add support for functions that set 'errno'
When accessing POSIX functions from a system's libc via Guile's dynamic
FFI, you commonly want to access the ‘errno’ variable to be able to
FFI, you commonly want to access the 'errno' variable to be able to
produce useful diagnostic messages.
This is now possible, check the Guile's dynamic FFI documentation for
the details, in paticular the following entries have been updated
accordingly: pointer->procedure, scm_pointer_to_procedure and
scm_pointer_to_procedure_with_errno.
This is now possible using 'pointer->procedure' or
'scm_pointer_to_procedure_with_errno'. See "Dynamic FFI" in the manual.
*** Add SRFI-25 implementation
Adds an implementation of SRFI 25 on top of Guile's native arrays. The
implementation does not introduce a disjoint type; Guile arrays and
SRFI-25 arrays can be used interchangably, though with different, partly
conflicting APIs.
*** Add SRFI-28 implementation
Adds an implementation of SRFI 28 Basic Format Strings.
*** The #!r6rs directive now influences read syntax
** The #!r6rs directive now influences read syntax
The #!r6rs directive now changes the per-port reader options to make
Guile's reader conform more closely to the R6RS syntax. In particular:
Guile's reader conform more closely to the R6RS syntax. In particular:
- It makes the reader case sensitive.
- It disables the recognition of keyword syntax in conflict with the
R6RS (and R5RS).
- It enables the `square-brackets', `hungry-eol-escapes' and
`r6rs-hex-escapes' reader options.
- It makes the reader case sensitive.
- It disables the recognition of keyword syntax in conflict with the
R6RS (and R5RS).
- It enables the `square-brackets', `hungry-eol-escapes' and
`r6rs-hex-escapes' reader options.
*** SRFI-14 character data set
** 'read' now accepts "\(" as equivalent to "("
SRFI-14 character data set has been regenerated for Unicode 8.0.0.
This is indented for use at the beginning of lines in multi-line strings
to avoid confusing Emacs' lisp modes. Previously "\(" was an error.
*** Web modules
** SRFI-14 character data set upgraded to Unicode 8.0.0
The (web server) module now exports 'server-impl' procedures, (web server
http) exports the 'http' server implementation.
** SRFI-19 table of leap seconds updated
Also, http location header accepts URI-reference, not just absoluteURIs.
** 'string-hash', 'read-string', and 'write' have been optimized
*** Strings
* New interfaces
The following 2 new procedures have been added: 'string-utf8-length' and
'scm_c_string_utf8_length'.
** New SRFI-28 string formatting implementation
'string-hash' has been optimized: this yields a 50% improvement on the
"narrow string" benchmark of 'hash.bm', 41% on "wide string", and 76% on
"long string".
** New (ice-9 unicode) module
'write' has been optimized: this shows a 19% improvement on the "string
without escapes" micro-benchmark of 'write.bm', and 12% on "string with
escapes".
See "Characters" in the manual.
'read-string' speed up: this yields a 20% improvement on the
"read-string" benchmark.
** Web server
'scm_string_hash' has been deprecated.
The (web server) module now exports 'make-server-impl', 'server-impl?',
and related procedures. Likewise, (web server http) exports 'http'.
'scm_read_string_like_syntax' now accept "\(" as equivalent to "(".
** New procedures: 'string-utf8-length' and 'scm_c_string_utf8_length'
*** Libguile
** New 'EXIT_SUCCESS' and 'EXIT_FAILURE' Scheme variables
Tow new macros have been added: 'SCM_VALIDATE_SIZE_COPY' and
SCM_NUM2SIZE.
** New C macro 'SCM_VALIDATE_SIZE_COPY'
*** New Module
** New C functions to disable automatic SMOB finalization
Add (ice-9 unicode) module.
The new 'scm_set_automatic_finalization_enabled' C function allows you
to choose whether automatic object finalization should be enabled (as
was the case until now, and still is by default.) This is meant for
applications that are not thread-safe nor async-safe; such applications
can disable automatic finalization and call the new 'scm_run_finalizers'
function when appropriate.
*** SMOBs
See the "Garbage Collecting Smobs" and "Smobs" sections in the manual.
Functionalities have been added to disable automatic finalization: see
the (Smobs) documentation node for the details and new functions.
** Cross-compilation to ARM
*** Posix
More ARM cross-compilation targets are supported: "arm.*eb",
"^aarch64.*be", and "aarch64".
'EXIT_SUCCESS' and 'EXIT_FAILURE' added and documented.
* New deprecation
*** Architectures
** The undocumented and unused C function 'scm_string_hash' is now deprecated
The following ARM target have been added: "arm.*eb", "^aarch64.*be", and
"aarch64".
* Bugs fixed
