Jose, CX1FK discovered critical bug - after double click to spot on band map nothing happened. Here is the fix.
Launchpad already finished building i386 version for Precise, Quantal and Raring. AMD64 version will be ready in next hour or so.
I'm very sorry for inconvenience.

More in download section.

This is mainly bugfix release. LoTW server has changed the URL to upload new QSO, I've had a few other important bugs fixed so new version is here. More in download section.
Launchpad seems to be quite busy. New packages will be available in next 5 hours or so.

Last week I decided to move CQRLOG source code to GitHub. So if you are a developer, you can send pull requests and it will be very easy to apply it to source code. The repository is here: https://github.com/ok2cqr/cqrlog and what you need to build CQRLOG is described in https://github.com/ok2cqr/cqrlog/blob/master/README.md

This is only bug fix release. I added MASTER.SCP file. If you already have installed version 1.5.3, please follow how-to from CX1FK posted here: http://www.cqrlog.com/node/890
 
Updated 2013-02-25 05:20 UTC - all files are available in download section. Packages for Precise Quantal are in my personal repo on Launchpad (how to add my ppa is described in download section).
 

After two months we have new version of CQRLOG with quite long changelog. Packages for Ubuntu 12.04 i386/amd64 are already finished on Launchpad so you can update using Update manager. More in download section.
