Summer is here, and so is your free CrashPlan upgrade! Here's what you'll find in this release:

Be “in the know” about the status of your backup. Now you can get a report (sent via email or Twitter) that allows you to review the status of your backups for all of your computers. Tell CrashPlan where to send status reports and how often you want to receive them. If you need it ASAP, you can even fire off a report right away.

Now you can receive CrashPlan alerts and status notifications via Twitter! Plus, if you want us to, we'll tell your followers on Twitter that you're using CrashPlan to help find that special backup buddy. Preferably one with a shiny new drobo.

We continue to work closely with Apple to insure CrashPlan works with Snow Leopard the moment it's released. If you're one of the lucky ones running it now, know that CrashPlan is working great with last few builds!

• If you are securing your backup archives with a private data password, you are now required to provide that password each time you restore.

• Emails coming from CrashPlan now come from noreply@crashplan.com instead of null@crashplan.com. Be sure to update your SPAM filter to accept messages from noreply@crashplan.com.
• For expert users, the Advanced Backup settings allow you to adjust WAN and LAN buffer size. Change this setting in only very specific, advanced networking configurations. If you are unsure, the default options are best.
• You will now receive backup alerts if your computer not connecting to CrashPlan Central after a period of time
• Windows: Improved open file support. VSS API support enhanced on certain platforms, should automatically work in situations that failed before.

• If you are securing your backup archives with a private data password, you are now required to provide that password each time you restore.
• If you're using FileVault, settings are now located on your encrypted volume instead of the unencrypted share. While this doesn't increase security, it is a better “best practice” and should lead to less confusion for those that are security-minded.

• We now show a few more details about each backup session.

• The online account page now shows each computer's ID (GUID). If you have multiple computers with the exact same name, the GUID helps you identify which computer is which.

• Restored Apple iWork Keynote files were not being displayed as a Mac bundle. Now when you restore Keynote files, they will display as a single file as they do in Finder. Viva la bundle!
• CrashPlan now updates the last backup date when there is nothing to backup. This change addresses a situation where backup warnings were being generated even though everything was fine. (But seriously - who doesn't touch a single file on their computer for a week?)
• Fixed rare private key situation which could temporarily prevent restoration. No data was at risk or lost, just caused a little inconvenience.
• Some users noticed that when backing up very large files, the estimated time remaining was inaccurate. We've adjusted the calculation so this value is more realistic.
• CrashPlan Central - Found bug which would cause clients to disconnect for no reason. No risk to data, but could slow down backups due to momentary interruption of service.
• Linux - fixed permissions issue on symlinks.
• Linux - fixed issue when no files are selected for backup.

• The Windows installer is now code signed. This insures the installer you're using has not be modified by a third party.
• As usual, we've enhanced the UI to make everything even easier to understand.
