Guile is Project GNU's extension language library, an interpreter for
Scheme, packaged as a library that you can link into your applications
to give them their own scripting language. Guile should eventually
support other languages as well, giving users of Guile-based
applications a choice of languages.
This is primarily a bugfix release. Highlights include:
Various architecture (and compiler optimization) related bugs have
been fixed: these changes should improve the situation on at least
ia64, arm, m68k, alpha, and powerpc.
SRFI-31 has been added (special form `rec' for recursive
evaluation). Try (use-modules (srfi srfi-31)).
SRFI-39 has been added (parameter objects)
SRFI-19 has been fixed: date-week-number now correctly respects
the requested day of week starting the week.
SRFI-4 has been overhauled. Bugs have been fixed, and performance
may be improved in certain situations. Among other things, large
values in 64-bit homogeneous vectors should print correctly now.
In the srfi-1 module's delete and delete! functions, the order of
the arguments to the "=" procedure now matches the SRFI-1
specification.
Bugs have been fixed that prevented the (re)generation of
psyntax.pp.
The use of scm_must_realloc() for memory which is scanned by GC
could trigger a GC scan of a free()d block of memory. This has
been fixed.
array-map! and array-map-in-order! now require at least one source
array. Previously a call without any source arrays like
(array-map! array proc) would cause a segfault. Now such calls
are properly rejected.
gethost no longer causes an exception when trying to throw an
exception.
call-with-output-string won't segv on a closed port. Now an
exception is raised.
open-pipe, open-input-pipe and open-output-pipe used to leave an
extra copy of their pipe file descriptor in the child, which was
normally harmless, but could prevent the parent seeing eof or a
broken pipe immediately. This has been fixed.
Properties set with set-source-properties! can now be read back
correctly with source-properties.
Guile is now compiled with -fno-strict-aliasing when gcc is
detected.
The --enable-htmldoc option has been removed from 'configure',
because support for translating the documentation into HTML is now
always provided. Use 'make html'.
It contains a link to the Guile FAQ and pointers to the mailing lists,
among other things.
Any bugs found in this release will be addressed by further bugfix
releases numbered 1.6.*. The next stable Guile release with
significant functional improvements will be version 1.8.0.
In between 1.6.x and 1.8.x, you can follow Guile development in CVS
and in the Guile mailing lists (see ANON-CVS and HACKING). Guile
builds from the development branch of CVS will have version number
1.7.0.
Guile versions with an odd middle number, i.e. 1.5.* are unstable
development versions. Even middle numbers indicate stable versions.
This has been the case since the 1.3.* series.
Actually we wanted to have the first pre-release for 2.2 out by now
but there are still a couple of minor API and UI changes that need to
be done. So this is another development snapshot on the road to GIMP
2.2. Hopefully the next release will be called 2.2-pre1 then.
This also means that we need to freeze the UI, translatable strings
and the APIs very soon now. So if you have any patches pending, make
sure you tell us about it. We will soon have to reject further changes
for 2.2. I still hope that we will at least be very close to the 2.2
release by the end of this month.
Please note that you cannot install gimp-2.1 side-by-side with
gimp-2.0 into the same prefix. A number of files will clash, so please
use a separate prefix to install this development version! For
details, please read the file INSTALL.
Here's an overview of the changes since 2.1.6 was released:
Added new preview widget that shows a scaled view of the full
drawable. Use it for Apply Lens, Blinds, Channel Mixer, Destripe,
Emboss, Illusion, Map Color, Max RGB, Plasma, Polar, Solid Noise,
Supernova, Whirl and Pinch.
Added "Open as Layer" functionality to the menus.
Implemented the recent-file-spec for shared storage of a list of
recently used files (really URIs).
Cleaned up plug-in procedure handling. Added the possibility to let
plug-ins and scripts run using a private GimpContext.
Added multi-line text entries for Script-Fu and Gimp-Python.
Cleaned up PDB API for brushes, gradients, palettes and patterns.
Deprecated lots of functions and added saner replacements. Added
gimp-context-* PDB namespace with replacements for some of the
deprecated stuff.
Let GimpView handle pixbuf previews. Added a (themable) drop shadow
to image-file previews.
Cleaned up the dbbrowser and plugindetails code and GUI and factored
out common code. Renamed both executables and menu entries.
Made tools cancelable with <Escape>.
Let GimpDialog add a help button to give easier access to the help pages.
