# Audacity 3.0.5

**Audacity 3.0.5 was released on 29 Sep 2021.**

### Changes and improvements since previous version

Audacity 3.0.5 replaces all previous macOS versions.

This is a hotfix release that fixes a bug on macOS that could corrupt project files when being opened via cmd+o on languages where the decimal separator wasn't a dot.

Other than that, this release is identical to Version 3.0.3.

### Supported Platforms

**Windows**

* Audacity 3.0.5 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.
* 3.0.5 does not support Windows XP.
  * You may try 2.2.2 on XP, but it is unsupported.

**macOS / Mac OS X**

* Audacity 3.0.5 is for Intel Macs running OS X 10.7 and later and macOS.
  * There are legacy versions for older OS X at <http://audacityteam.org/download/legacy-mac/>.

**Linux**

* In addition to the traditional update path via package managers, Audacity 3.0.3 and onwards are distributed as an AppImage. The AppImage gets updated at the same time as the Windows and macOS versions, so if you collaborate with users on those platforms, you may want to use the AppImage over your distribution's package manager.
* Linux support is tested on Ubuntu Linux.
  * Other Linux distributions should work, but aren't tested by the Audacity team.

## 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/additional-resources/changelog/older-versions/audacity-3.0.0/audacity-3.0.5.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.
