The Nokia Software Updater today got updated to V1.6.11, though any changelog is officially not yet out but there were no changes to the UI to suggest a major update.
So we can expect this version to have better stability and some bug fixes, change log when available from Nokia will be posted here.
As Nokia Software Updater automatically checks for updates so all those of you who have it already installed can run the application and update and for all others click here to download it.
UPDATE: Some blogs are reporting V1.6.13 is already out .. Dunno whats diff between them .
