### Changes and improvements since previous version

Audacity 2.4.2 replaces all previous versions.

* Over 30 bugs fixed since 2.4.1

Full details of new features in the visual guide to [New features in Audacity 2.4.2](/au3/additional-resources/changelog/older-versions/audacity-2.x/audacity-2.4.0/audacity-2.4.2/new-features-in-audacity-2.4.2.md)

### Supported Platforms

**Windows**

* Audacity 2.4.2 requires the CPU to support the [SSE2 ](http://en.wikipedia.org/wiki/SSE2)instruction set which should be available on any Intel hardware produced after 2001 and any AMD hardware produced after 2003.
  * To check what SSE levels your CPU supports, you can install [CPU-Z](http://www.cpuid.com/softwares/cpu-z.html).
  * If your hardware only supports SSE, you may download Audacity 2.0.6 see the [Legacy Windows](https://www.audacityteam.org/download/legacy-windows/) page on the Audacity Website.
* 2.4.2 does not support Windows XP.
  * You may try 2.2.2 on XP, but it is unsupported.

**macOS / Mac OS X**

* Audacity 2.4.2 is for Intel Macs running OS X 10.7 and later and macOS.
  * There are legacy versions for older OS X at <https://audacityteam.org/download/legacy-mac/>.

**Linux**

* Linux support is tested on Ubuntu Linux.
  * Audacity may compile on Gentoo, Debian, Mint.
  * Audacity does not currently compile on SuSE Linux.

### Interactive Buglist Page

*We probably track more bugs than you are interested in...*

On the dynamic buglist page you can select to view:

* Complete list of bugs in 2.4.1 that we have fixed for 2.4.2
* Known bugs on the OS you use Mac, Windows or Linux.
* Known bugs to do with accessibility or localization.
* Workarounds for some bugs.
* Serious bugs and less serious bugs.

You can choose various combinations of these. However, there are probably too many minor bugs and too much detail on that [dynamic buglist page](https://github.com/audacity/audacity-support/blob/main/additional-resources/changelog/older-versions/audacity-2.x/audacity-2.4.0/audacity-2.4.2/broken-reference/README.md) for most users.

We **do** use this detail in our own QA work.

### Highlighted Issues

* Below are listed what we believe are the most common and important issues with 2.4.2 for most users.

**Accessibility**

* Far less of Audacity is properly accessible to visually impaired users than we would like. Currently the best supported platform for accessibility is Windows. We lost a lot of custom accessibility programming when we had to move to a more recent version of the wxWidgets library.

**Internationalization**

* Audacity is only partially translated in many languages. We also have some issues, for example, with Right-To-Left Languages.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.audacityteam.org/au3/additional-resources/changelog/older-versions/audacity-2.x/audacity-2.4.0/audacity-2.4.2.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
