This page is an overview of prominent new functionality that has been introduced in Audacity 2.4.2
Version 2.4.2 is primarily a maintenance release for bug-fixing, so there are not many new features.
Details of all the major changes since 2.4.1 can be found in Audacity Release Notes 2.4.2.
A new command has been added to the Help menu: Help > Reset Configuration.
This resets your Audacity configuration, preferences (except Extended Import), export settings and toolbars, to default settings.
Be aware that this command acts immediately with no dialog and no choice of actions or chance to abort.
Undo is not available for this command.
User presets in Effects, Generators and Analyzers are left untouched, as are any Macros you may have created and plug-ins.
Audacity now supports LAME's gapless playback info, allowing MP3s to be exported and imported without additional padding.
Other applications that support the LAME tag, for example audio player applications, will be able to read MP3 files exported by Audacity without the padding.
In less than a month we have foxed a further 29 bugs in this maintenance release.
Here is a small selection of some of the most important.

P1 - Mac: Attempting to export as M4A(AAC) yields an FFmpeg error message
