# New features in this release

From Audacity Development Manual
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.

## Contents

1. Easy configuration reset
2. MP3 exports without padding
3. Bug Fixes

## Easy configuration reset

A new command has been added to the Help menu: Help > Reset Configuration.

This resets your Audacity configuration, preferences, export settings and toolbars, to default settings.

| 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.

Please see Reset Configuration for further details.

## MP3 exports without padding

MP3s are now exported from Audacity with no padded (unwanted) short silence at the beginning and end of the MP3.

This was done as part of the work in fixing long-standing Bug #421
