Moving towards openness

Remember the days when every website wanted to maintain its own database of users and related data? To download some restricted content you have to register there, provide a password, successfully forget it after a couple of minutes and use "Restore password" feature every time you visit the website later.

The same kind of website was our corporate X-tensive.com website. Moreover, our support website was configured to work with users from x-tensive.com only. Until...

Until we rejected the model above and switched to OpenID authentication scheme and made all versions of DataObjects.Net available for download without registration. The same change was applied to support.x-tensive.com — now anyone who has OpenID may log in and post an issue/feedback.

Having that done, we closing user registration area on x-tensive.com as now it doesn't have any sense, however, all user accounts will be preserved and users may sign in in their x-tensive.com profile as usual.

Note for owners of DataObjects.Net licenses: we launched new customer area, don't miss it. All your license-related data is migrated from x-tensive.com to get.dataobjects.net website.

So anyone, even an owner of Community edition has a chance to dive deep in DataObjects.Net white and black magic. The price for the package is set to $500. The source code is available in download area of our website.

The area can be accesses by clicking on 'My Account' link in the main menu:

Soon you'll receive our invitation e-mail. We need you to log in the area to get your licenses associated with your account. Don't forget to periodically check your mailboxes!

DataObjects.Net 4.5.3 RC and 4.4.3 RC3 are available.

Both contain the same fixes that are listed below:

• Fixed index duplication under certain scenarios (see this for details)
• Fixed error about duplicate index name under certain scenarios (see this for details)
• Added SessionOptions.SuppressRollbackExceptions

Rollback exceptions suppression

Option SessionOptions.SuppressRollbackExceptions tells DataObjects.Net to catch (and log) any exception that occurred during rollback. Rollback typically occurs when some exception is already thrown. So any exception during rollback will cause original exception to be lost. New option could be used to prevent such behaviour.

Migration path

No special migration is required.
