CHIRP is distributed as a series of automatically-generated builds. Any time we make a change to CHIRP, a build is created for it the next day. Thus, CHIRP is versioned by the date on which it was created, which makes it easy to determine if you have an older build. We don't put experimental things into CHIRP before they are ready, except where specifically called out with a warning. Thus, you do not need to worry about finding a stable version to run. You should always be on the latest build available.

Upgrading: You do need to uninstall an existing version of CHIRP before installing a newer one. Just install the new one and it will replace the existing copy!

You can find a complete test report of the current build here and a matrix of supported models and features here

Windows Users¶

CHIRP runs on Windows 2000, XP, Vista, 7, 8, and 10. Older versions of Windows are not supported
Most users will want to download the installer.exe file, which installs CHIRP like a normal application
The win32.zip file is for advanced users wishing to run CHIRP without installing

MacOS Users¶

Chirp Software For Mac

OS X support is limited to Intel architecture. PowerPC is not supported.
Chirp.app is unsigned. With default security settings, you will need a special procedure to run it: Application Security in 10.9.

Homebrew users can install Chirp without the KK7DS runtime by running brew install tdsmith/ham/chirp and then running chirp from the terminal.
However, running CHIRP using Homebrew is obsolete. MacOS Unified Application build is now the recommended way.

More useful tidbits can be found at MacOS Tips.

Linux Users¶

Most Linux users will want the flatpak executable, which has the entire runtime integrated and should 'just work.' If you are running an old or weird distro and want the source distribution, grab the tarball from the above link.

New Features:

Added Jaiku integration.
New set of six nature-themed color schemes.
Added Identi.ca support for private/direct messages and @ Reply marking.

Bug Fixes and Improvements:

Added relative time support for months and years.
Added a check so that pasting into the text area wouldn't overflow the character counter.
Fixed a bug where searching wouldn't correctly search updates containing commas.
Fixed a posting bug which truncated posts containing non-ASCII characters.
Chirp no longer attempts to refresh the feed if the preferences are shown.
Added a new loading indicator.
Changed the wording of the errors to make them more informative.
Lowered the request timeout to 15 seconds (7.5 seconds for updating).
Added a feature to automatically disable the 'Done' button unless a username and password are entered.
Removed the two-minute refresh interval; you can still refresh by showing and hiding the Dashboard.
The 'Update' button now mentions the latest version available.
Plugged several more memory leaks. Note: Despite our fixes, Dashboard still has problems with memory leaks. This is a bug that Apple is working to correct.
Fixed a problem with an HTTP 304 error being occasionally reported.
Numerous bug fixes and other code improvements.

Known Issues:

Jaiku won't immediately refresh the stream after you post an update. This is a bug with the Jaiku API, as it won't push the updated stream right after the update is posted. Refreshing the stream by showing and hiding the Dashboard should show the update.
