Title of the thread gives you pretty much everything you need to know. I know when a new update for BBlog comes out it feels like a little bit of a hassle to go to the BBlog website and hit the download option. Is there any way a feature could be implemented so that when an update is available, you could just click an "Update" button directly in BBlog so you don't have to leave the page to update? Just a suggestion I feel could benefit the BBlog experience.
You should use auto update of your browser, as most other people do.
You will find how you do this at the download page, directly bellow the download button.
It happens automatically but you can start the update manually if you don't want to wait.
