2.  Changes in version 1.3.5

Recording  / Playback:
	* Several bugs fixed so that latency correction should be better, and more
	   devices work correctly. Problems with invalid sample rates under Linux
	   should be much rarer.
	* Newer version of Portaudio library.
	* New feature to record onto the end of an existing track
	   (hold Shift while clicking Record).

Import / Export:
	* Updated versions of Libogg, Libvorbis, Libflac, Libsndfile and Twolame
	   libraries.
	* Handling of unsupported file formats more informative.
	* Handling of file names with slashes on OS X improved. New dialog
	   allows replacement of illegal file name characters on all platforms.

Interface:
	* Improved scaling and layout for rulers and VU meters.
	* Envelope fixes/improvements including full control of undo/redo.
	* New keyboard shortcuts and improved menu navigation.
	* Preferences: More intuitive tab arrangement. New options for
	   mute/solo and Metadata Editor behavior. Language can now be
	   changed without restart.
	* Expanded Build Information tab.

Effects:
	* New Vocal Remover plug-in, improvements for Generate effects.

Compilation:
	* Fixes when building Audacity with libraries disabled.
	* Improvements to make Mac and Solaris builds easier.

Security:
	* Full fix for issue CVE-2007-6061 on systems where temporary directories
	   can be changed by other users (thanks to Michael Schwendt).

Miscellaneous:
	* Updated translations for many locales.
	* Several stability improvements.


--------------------------------------------------------------------------------

3. Known Issues

Please also check:
  http://audacityteam.org/wiki/index.php?title=Known_Issues

for details of any issues that have been identified after release of
this version.

 * If Audacity is built from CVS with wxWidgets 2.6.4 or later, the Escape
    key does not cancel most dialogs. This is due to a wxWidgets bug.

    In builds provided by the Audacity project, wx 2.6.4 has been patched.
    This means that all dialogs can be cancelled by Escape when first
    opened, but in Preferences and Effect dialogs, keyboard users must
    now tab twice to reach the first field of the dialog. Additionally, for
    Preferences, GVerb, Hard Limiter, SC4 and user-added LADSPA/VST
    effects, once the user interacts with the dialog, it cannot then be
    cancelled by Escape without first tabbing to the OK or Cancel buttons.

 * Export Multiple fails with no export or warning if an empty label is
    encountered.

 * The preference "Hold recorded data in memory until recording is stopped" is
    misnamed. It caches most audio data for the duration of the session, including
    project data and imported files. Enabling it may cause a crash when making
    long recordings or opening large files or projects.

 * A few interface elements do not change language without restart.

 * Calculation of "disk space remains for recording (time)" is incorrect when
    recording in 24 bit quality. You may record for 50% longer than the indicated
    time.

 * Pressing Play (but not spacebar) in a second project when another is already
    playing stops playback of the first project.

 * Projects created by Audacity 1.1.x may open incorrectly.

 * Metadata such as ID3 tags is not fully imported and exported for all supported
    file formats. MP3 tags *are* correctly imported and exported to the current ID3
    specification, but some players don't fully support this specification, so may not
    see all the tags.

 * No warning is given if File > Save or File > Save Project As... is carried out with
    no tracks open.

 * Not all menu items are correctly enabled when the preference: "Select all audio in
    project, if none selected" is checked.

 * Beep on completing long process may not be audible on many systems.

 * Audacity can import and display MIDI files, but they cannot be played
    or edited.

 * Windows only: Welcome Message: On some systems/browsers, links are not
    brought to top, and some screen readers that otherwise work well with Audacity
    cannot read its text.

 * Windows (reported on): There have been reports of clicks during recording on
    some Windows XP systems using Audacity 1.3.4, where 1.2.6 had no problem.
    It is not clear if 1.3.5 will have this issue or if it will occur on other operating
    systems. Users can help us by sending any reports of this problem to:
      audacity-devel@lists.sourceforge.net

 * Windows only: Audacity is incompatible with some professional sound cards
    and may crash if one of these cards is the default when you open Audacity.
    As a workaround, make a different sound card your default when using
    Audacity, but please let us know if this affects you so that we can track down
    and solve the problem.

 * Mac OS X only: Some users find that after running Audacity other media
    players don't produce any sound or crash. Audacity tries to select the best
    quality settings your system is capable of, to give the best recordings
    possible. Some sound drivers also retain these settings as defaults for
    other applications, which can cause these symptoms

   To get round this, enable the option "Do not modify audio device settings"
   on the Audio I/O tab of the preferences, and make sure that your sound
   device is set up (in the Apple Sound and Midi Setup utility) to work in
   stereo, 16bits, with a sample rate of 44100Hz or 48000Hz.  More help at:
      http://audacityteam.org/wiki/index.php?title=Mac_Bugs#Loss_of_sound_after_running_Audacity

 * Mac OS X only: Portable settings aren't picked up, and the default
    settings (in the default location) are always used. See this page for
    a workround:
      http://audacityteam.org/wiki/index.php?title=Portable_Audacity

 * Linux only: Audacity now supports interfacing with Jack, however this has
    not been tested, and is known to have a number of issues with both
    reliability and useability. Patches to improve both will be welcomed.

 * Linux (reported on): The first file imported into a project no longer
    changes the project rate to the file's rate, if that rate is absent from the
    project rate list.

 * Linux (Debian-derived) only: Audacity configure script does not detect
    libsoundtouch on the system and so Change Pitch and Change Tempo
    effects are disabled. This is a debian bug (#476699), which can be
    worked around by symlinking /usr/lib/pkgconfig/soundtouch-1.0.pc
    to /usr/lib/pkgconfig/libSoundTouch.pc.

Also note that the Windows installer will not replace 1.2.x installations, but will
install alongside them.

Changes in 1.3.0:

   New features
   The new features in Audacity 1.3 have been grouped into the
   following six major categories.

   1. Collapse/Expand Tracks
      In Audacity 1.3, every track has an upward-pointing triangle at
      the bottom of the label area on the left side of the track.

   2. Multiple clips per track
      In Audacity 1.2, there is one audio 'clip' per track. There is
      no easy way to time-shift part of a track without moving the
      rest. In Audacity 1.3, you can split a single track into multiple
      clips. You can move these clips around between different tracks,
      making it easy to construct complex compositions out of hundreds
      of smaller audio samples.

   3. Selection Bar
      In Audacity 1.2, the current selection is contained in a
      status bar at the bottom of the window. In Audacity 1.3,
      this is replaced by a fully functional Selection Bar, which
      displays and controls the current selection (your choice of
      Start and End, or Start and Length), and the current audio
      position. The selection bar is fully editable - just click
      in any field and type to change the current selection precisely.
      In addition, many formatting options allow you to view times in
      different units, such as samples, CD frames, or NTSC video frames.

   4. Improved Label Tracks
      Label Tracks are Audacity's way for you to create markings 3
      and annotations within your project. In Audacity 1.3, Label
      Tracks are much improved, with support for overlapping labels,
      and support for modifying both the left and right edge of the
      label region just by clicking and dragging.

   5. QuickTime and Audio Units on Mac OS X
      On Mac OS X, Audacity can now import and audio file supported
      by Apple's QuickTime technology. This includes .MOV and .MP4
      (AAC) files. Unfortunately encrypted audio files (such as
      those from the iTunes Music Store) cannot be imported directly
      into Audacity - Apple does not allow this to be done easily
      because it would be too easy to circumvent the encryption this way.

      Also on Mac OS X, Audacity now supports Audio Unit plug-ins.
      Audacity searches for Audio Units in the usual location, in the
      system or user's Library folder.

   6. Other features
      Better performance with large projects

      Project integrity check on open

      Transcription toolbar

      Upload

      Batch

      Cut lines

      CleanSpeech


Changes in 1.2.4:

  * The File menu now includes a list of recent files.

  * The "Generate Silence" effect now prompts for a length.

  * Audacity is now built with Vorbis 1.1, which features better encoding
    quality and file compression.

  * Dragging sound files into the Audacity window now works on Mac OS X
    and Linux, as well as Windows.  (Before, it worked only on Windows.)

  * The "View History" window can now discard old undo levels to save disk
    space on Windows.  (This previously worked only on Linux and Mac.)

  * "Preferences" command is now in Edit menu.

  * "Plot Spectrum" command is now in Analyze menu.

  * Opening a project file saved by a later version of Audacity displays
    an intelligent error message.  Also, trying to import a project file
    (instead of open it) displays an intelligent error message.

  * Audacity now compiles in Visual C++ .NET 2003.

  * Other minor bug fixes.

  * New or updated translations: Arabic (ar), Czech (cs), Finnish (fi),
    Hungarian (hu), Japanese (ja), Norwegian (nb), Slovenian (sl),
    Simplified Chinese (zh_CN), Traditional Chinese (zh_TW).


Changes in 1.2.3:

  * Fixed a bug that caused recording to stop or display incorrectly
    after about 50 minutes on some Windows systems.  (This was partly
    fixed in Audacity 1.2.2, but still didn't work on some systems.)

  * The Change Pitch and Change Tempo effects have been upgraded to
    use a new version of the SoundTouch library by Olli Parviainen,
    with better speed and higher quality.

  * libsndfile has been upgraded to version 1.0.11.

  * Fixed a bug that caused the program to run slowly when using the
    Envelope tool.

  * Shift-clicking on a mute or solo button now un-mutes (or un-solos)
    all other tracks.

  * Nyquist plug-ins can now accept strings as input.  Also, a "Debug"
    button has been added to Nyquist effect dialogs, which allows you
    to see all of the output produced by Nyquist, for aid in debugging.

  * When the audio file referenced ("aliased") by an Audacity project is
    missing, Audacity will now always play silence.  Before, Audacity
    would sometimes repeat the most recent audio that was played previously.

  * VU Meters will now always reset when audio I/O has stopped.

  * Fixed a major Mac-only bug that was causing Audacity to crash at seemingly
    random times, but especially during audio playback and recording.

  * New or updated translations: Italian (it), Hungarian (hu),
    Ukrainian (uk), Spanish (es). Polish (pl), Simplified Chinese (zh),
    Norsk-Bokmal (nb), French (fr).


Changes in 1.2.2:

  * VU Meters added for both playback and recording.  Click on
    the recording meter to monitor the input without recording.

  * Export Multiple - new feature that lets you export multiple
    files at once, either by track, or split based on labels.

  * Attempt to automatically correct latency in full-duplex recordings.
    (This does not work perfectly, and is not yet supported on all
    systems.  It will improve in future versions.)

  * Fixed a serious bug that could cause data loss when you save and
    then reload and re-edit an Audacity project containing repeated
    or duplicate data.

  * MP3 tags dialog will only pop up the first time you export as
    MP3; after that it will not pop up again as long as you have
    filled in at least one tag.

  * You can now add a label at the current playback position - in
    the Project menu, with a shortcut of Ctrl+M.

  * Clicking on a label now selects all of the tracks, making it
    easier to use the label track to recall selections.

  * Windows: Fixed a crash in the Time Track "Set Rate" command.

  * Fixed a bug that caused problems with recordings over 45 minutes
    on some Windows systems.

  * Mac OS X: Improved support for the Griffin iMic by fixing a bug
    that was causing it to always record in mono instead of stereo.

  * Added support for Software Playthrough (listen to what you're
    recording while recording it, or while monitoring using a VU
    meter) - this makes it possible, for example, to record using one
    audio device while listening to it play through a separate device.

  * Unix/Linux: Fixed freeze caused by captured mouse when audio
    device hangs.  (Audacity may not respond, but it will no longer
    freeze all of X.)

  * Fixed a cosmetic bug that caused improper waveform display if
    you tried to open an Audacity project saved on a different
    platform (e.g., copying a project from a Mac to a PC).

  * Fixed bug that could cause instability when pasting, splitting,
    or duplicating a label track.

  * You can now change the font of a label track by choosing "Font..."
    from the label track's pop-up menu.

  * Basic printing support has been added.  Currently it scales the
    entire project to fit exactly on one page.  Try printing in
    landscape orientation for best results.

  * Mac OS X and Windows: Audacity ships with a newer version (1.0.1)
    of the Ogg Vorbis encoder.  Vorbis compression will now have higher
    quality and smaller file sizes.

  * Fix a bug that occasionally caused crashes when applying effects
    to split tracks.

  * Zoom In / Zoom Out now properly disable when they're not available.

  * Fixed disk memory leak in Preview

  * Other minor bug fixes and performance improvements.


Changes in 1.2.1:

  * The following translations have been added or updated:  Finnish,
    French, Hungarian, Italian, Japanese, Norwegian, Polish, Russian.

  * Fix a bug that could cause data to be lost when pasting audio
    from one project into another, after the first project has been
    saved and closed.

  * Fix a possible crash when opening or resizing the Equalization
    window, especially when using large system fonts.

  * Don't allow percentages less than -100% in Change Pitch/Speed/Tempo
    effects (fixes a possible crash).

  * Fix a crash when the temporary directory is not available on startup.

  * Correctly load ID3 tags saved in Audacity project files.

  * On Linux and OS X, store lockfiles in the temp directory instead of
    the user's home directory.  This fixes problems in lab environments
    where users have restricted or network-mounted home directories.

  * Fix a bug that prevented Nyquist effects from running when certain
    regional settings were activated.

  * Fix a bug in the Quick Mix command that could cause old temporary
    files to not be deleted.

  * Linux: Fix endianness problems in playback on PowerPC.

  * Linux: Fix compilation problem in Nyquist on MIPS.

  * Linux: Include a more recent PortAudio v19 snapshot (fixes compilation
    problems when building with the --with-portaudio=v19 option).

  * Two new Nyquist plug-ins: "Cross Fade In" and "Cross Fade Out."

  * Other minor bug-fixes.


Changes in 1.2.0:

  * New cross-fade effects.

  * Fix problem where samples were drawn in the wrong position
    when zoomed all the way in.  This caused the drawing tool
    to move a different sample than the one under the cursor.

  * Don't use id3v2.4 tags, which are not yet supported by
    most players.  (This was fixed in 1.2.0-pre2, but appeared
    again by accident in 1.2.0-pre3.)

  * Correctly display translated messages in the status bar.

  * When the cursor is on-screen, the Zoom In button now zooms
    to the area around the cursor.

  * Mac OS X: Fixed audio problems on the Apple PowerMac G5.

  * Linux/ALSA: Work around a bug in ALSA's OSS emulation that
    caused Audacity's playback cursor to move too quickly.

  * Microsoft Windows: The Audacity source code should now
    compile out of the box on Windows.

  * Many new/updated translations.


Changes in 1.2.0-pre4:

  * Fixed problems that could occur when importing certain
    non-seekable PCM audio files, such as GSM610.

  * Fixed bug that was causing the samples to shift off-screen
    horizonally when zoomed in very far and the track had a
    time-shift offset.

  * Fixed bugs in the new resampler that added noise to resampled
    audio on some systems. If you experienced noise when exporting
    to a WAV, MP3 or OGG file you may have been bitten by this bug.

  * Fixed bug that led to occasional crashes when using the
    time-shift tool in conjunction with high zoom factors.

  * Dithering is now only applied on export when it is really
    necessary (e.g. when converting float samples to 16-bit).

  * Files that only contain mono tracks are now automatically
    exported to stereo files when they contain tracks which are
    panned to the left or the right.

  * The Delete key can now be used to delete the current selection,
    in addition to the Backspace key.

  * Fixed bug where Audacity didn't ask whether to save
    changes if you close the project or exit while recording.

  * Mac OS X: Supports Playthrough (listen to what you're recording
    while recording it) if your hardware device supports it.

  * Mac OS X: Audacity is now a package (you can right-click on
    Audacity.app and select 'Show Package Contents').  Launch time
    has improved significantly.

  * MS Windows: Fixed problem that caused Windows XP to use
    the short name of a file ("TESTFI~1.AUP"), which led to
    problems when the file was later opened again using the
    long file name.

  * MS Windows: Fixed bug that caused file exports to fail
    if the destination directory was the root folder of a
    Windows drive.

  * MS Windows: Audacity's application information which
    is written to the Windows registry now always contains
    the full path to the executable.

  * MS Windows: Fixed problems in trying to set the Windows
    registry as non-admin user, for file-type associations.

  * Make sure the "Save" command is enabled after changing
    gain and pan sliders.

  * Updated translations.  Added translator credits to the
    "About" window in localized versions.


Changes in 1.2.0-pre3:

  * Fixed bug where Export is grayed out when nothing is

    rather than the playthrough level of the recording source.

  * Fixed bug that caused corruption to 16-bit stereo recordings.

  * Fixed bug that caused data loss if you deleted all tracks in
    a saved project and then open a new file into the same window.

  * Added support for alternate audio button order (in Interface
    preferences)

  * Added preliminary support for wxX11

  * Added fully transparent Windows XP icon

    devices exist, or if the audio device doesn't support the
    mode you selected.

  * Audacity no longer sets the process priority to high while
    recording on Windows.  Users can still do this manually
    using the Task Manager.

  * Fixed bug that caused last ~100 ms of the selection to get
    cut off on Windows.

  * Fixed FFT Filter and Equalization effects dialogs.

  * Fixed bugs in Unix build system (DESTDIR in locale directory,
    choosing libsamplerate instead of libresample)

  * Support for LADSPA plug-ins on Windows added, and
    three open source LADSPA plug-ins ported to Windows
    (GVerb reverb, SC4 compressor, and Hard Limiter)


Changes in 1.2.0-pre2:

  * Online help completed.  The full manual is nearly complete
    and will be posted to the website for online browsing shortly.

    minimum rate of resampling.

  * Audacity now supports LADSPA plug-ins on all platforms, and
    supports VST plug-ins through an optional LADSPA plug-in
    called the "VST Enabler", which you can download separately.
    Because of licensing issues, Audacity cannot be distributed
    with VST support built-in.

  * Mac OS X keyboard shortcut problems have been fixed.

  * Mac OS X audio muting problems have been fixed.

  * Mac OS X playback/recording cursor sync problems have been fixed.
