        * Fixed bug preventing device dialog being reopened when
          closed via the window manager.

All users with speex handling enabled should upgrade.


Tue Jan 30 2007 -- Version 0.9.2
--------------------------------

New in this release:

        * ALSA is now the default driver. see README.OSS for oss
        * minimum supported gtk version raised to 2.4 
        * added the "hand tool" for panning the display with inertia
          (Radoslaw Korzeniewski)
        * can now open multiple files via the gtk file selector
        * implemented accel editing via the usual gtk method
        * added tdb lock override (Takashi Iwai)
        * remove support for libsndfile0 (Erik de Castro Lopo)
        * remove direct flac support as it's supported by libsndfile now
          (Erik de Castro Lopo)
        * added a new splash screen (Pascal Klein)
        * fix segfault when closing windows while others were still loading
        * other bugs addressed and changes made. run "svn log" on a copy of svn
          trunk for details, or check http://trac.metadecks.org/timeline
        * released 0.9.2


Mon Jan 30 2006 -- Version 0.9.1
--------------------------------

This is a maintainance release.

The previous release (0.9.0) had a bug that prevented sweep from
populating the ALSA devices in settings. The bug was only apparent
when you built with ALSA and didn't have a previous installation
of sweep that used ALSA.

If you installed sweep 0.9.0 and had problems getting any sound
output then please upgrade to 0.9.1.

Mon Aug 22 2005 -- Version 0.8.4
--------------------------------

This is maintainance release, including:

        * updates for ALSA 1.0 (Daniel Dreschers, Charles Turner),
        * a new Polish translation (Radoslaw Korzeniewski),
        * an updated russian translation (Alex Prokoudine),
        * a small fix to the German translation, and
        * various minor tweaks and improvements.

This is likely to be the last Sweep release based on GTK+-1.2. Further
development will use GTK+-2.0 for the interface.

Over the last year, Peter Shorthose has developed a comprehensive set of
GTK+-2.0 patches for Sweep, and will handle their merging and ongoing
release management towards Sweep 1.0. Welcome Peter!

The trunk of sweep CVS has been migrated to a new Subversion repository.        
You can check it out by:                                                        

  svn co http://svn.metadecks.org/sweep/trunk sweep                             

svn.metadecks.org can also be browsed via trac at:                              

  http://trac.metadecks.org/                                                    


Fri Apr 30 2004 -- Version 0.8.3
--------------------------------

This is a maintainance release, including a new Spanish translation,
various bugfixes and no new functionality.

Sweep has moved back into CVS at SourceForge. Five new developers have
been added to the project: Yuri Bongiorno, Erik de Castro Lopo, Torben 
Hohn, Andr? Pang, and Alexandre Prokoudine.

Internationalization (i18n) improvements:
                                                                               
        * a new Spanish translation by Juan Manuel Martinez
        * an updated Italian translation by Yuri Bongiorno

Bugfixes:

        * resampler bug fixed by Erik de Castro Lopo 
        * made main scrollbar arrows useful (bug #821596)
        * seven other bug reports closed
        * compile warning fixes for GCC3

The dependency on libtdb has been removed. TDB sources are now pulled
directly from the upstream Samba subversion repository.


Wed Apr 30 2003 -- Version 0.8.2
--------------------------------

This release contains support for ALSA 0.9; this is configurable and could
do with widespread testing.
                                                                                
To build with ALSA support, simply configure with:
                                                                                
        ./configure --enable-alsa
                                                                                
Note that this will build a binary which will work with ALSA only, and
not attempt to use OSS. In future this will be replaced with plugins
for different pcm i/o methods, which should ease binary distribution.


Internationalization (i18n) improvements:

        * a complete audit of untranslateable strings, including
        mis-configured source files and unmarked strings, by
        Silvia Pfeiffer.

        * a new Greek translation by Dokianakis Fanis
        * a new Russian translation by Alexandre Prokoudine
        * an updated Italian translation by Yuri Bongiorno
        * an updated German translation by Silvia Pfeiffer

There is a new mailing list: sweep-i18n. List information is at
http://lists.sourceforge.net/lists/listinfo/sweep-i18n


Additional changes include:

        * added VBR without DTX option for Speex 1.0 speech encoding
        * improved accuracy of sliders in processing dialogs

see http://www.metadecks.org/ .

New in this release:

        * a new monitoring subsystem for use in DJing and live performance.
        Users with two sound cards can use headphones for monitoring, to

        * the Italian translation of the user interface was updated by
        Yuri Bongiorno.


New at metadecks.org:

    Notes for the tutorial "Using Sweep: Fun with Scrubby" are now
    available online in HTML, PostScript and PDF formats at:

        http://www.metadecks.org/software/sweep/tutorials/

    This is a brief overview of the tutorial given at linux.conf.au 2003
    in Perth, Australia; the real thing is live and very, very loud.


Sat Jan 4 2003 -- Open Sound System's killer app of the month
-------------------------------------------------------------

Sweep has been selected as the killer app of the month for January 2003 by
Open Sound System (OSS), developers of the most widely used digital audio
architecture for UNIX. 


Fri Dec 20 2002 -- Version 0.5.13
---------------------------------

This release contains build fixes for NetBSD and cleanups by Erik de
Castro Lopo to fix preprocessor pasting warnings.

It also features new fade in and fade out filters.

Conrad will be presenting two sessions at linux.conf.au, January 22-25 2003
in Perth, Australia; a tutorial titled "Using Sweep: Fun with Scrubby", and
an overview of Sweep's internals and plugin development.


Fri Dec  6 2002 -- Version 0.5.12
---------------------------------

New in this release:

        * an updated Italian translation from Yuri Bongiorno

        * resample (sample rate conversion): change the sample rate of a
        file, for example from CD format to DAT format, or to any arbitrary
        sample rate. This requires Erik de Castro Lopo's newly released
        libsamplerate, available from http://www.mega-nerd.com/SRC/

        * preview cut: hear how the area around the selection will sound
        after the selection is cut out, including the parts between
        selection regions for multi-region selections.

        * preroll to cursor: play one second of sound leading up to the
        cursor; useful for hearing the cursor position without moving it.

Bugs were fixed in MP3 loading and pitched playback (using QWERTY keys).


Thu Nov 28 2002 -- Version 0.5.11
---------------------------------

New features in this release include:

        * mixing and crossfading paste methods: copy a region from one file
        and mix or fade it into another file or elsewhere in the same file,
        with control of source and destination levels and phase.

        * navigation shortcuts to move between selection edges: move the
        cursor between the start and end of selection regions, and to the
        next edge of a multi-region selection, with Ctrl + Arrow Left/Right

        * view memories: assign the viewable area to a number on the numeric
        keypad with Ctrl+<Num>, and zoom back to it later by pressing that
        number. (NB. Num Lock must be on on your keyboard).

        * support for Speex 1.0beta3 ultra-wideband mode (32kHz). Speex is
        a high quality, patent-free and open source voice codec.

        * support for full-file application of Secret Rabbit Code

Additionally, minor bugs were fixed affecting portability of system error
handling and detection of MP3 files.
