SoHO Viewer 2.1 issues

Since version 2.1 SoHO Viewer has notifications push, this new functionality has caused an overload on the gateway which has resulted on severe application freeze on launch. The gateway has since been re-designed to support a greater load.

A new update of SoHO Viewer (2.1.1) is currently waiting for review, this update will help to further more reduce the stress on the gateway and prevent the application from freezing if such an overload should occurs again.

SoHO Viewer 2.0.1

SoHO Viewer is now in version 2.0.1

This version is only mean to fix a possible issue while being connected through a proxy server.

SoHO Viewer 2.0

SoHO Viewer is now in version 2.0.

This version resolves a major fault: SoHO Viewer was always re-downloading all pictures at launch.

I am pleased to announce you this fault is no more. The application now uses a gateway in order to know which pictures has been updated and should be downloaded.
