Version 1.1 adds the following features:
Email signups, password resets, and profiles are now supported. You can configure the signup and reset password emails inside the App_Data/EmailTemplates folder. To enable an SMTP server for signups, you need to configure the SMTP server inside the web.config file, under the system.net setting (an example is given).
Version 1.1 now uses email addresses for logins, rather than usernames.
The user signups also support Recaptcha as a form of spam protection. This can be turned on inside the admin settings page.
Roadkill is now enabled to support SQlite, SQL Server CE, mySQL, and the untested Postgres, DB2 and Firebird. It defaults to SQL Server 2008 if you do not change the setting in the web.config.
To upgrade from version 1.0.1 please read the 'READMEFORUPGRADING1.0to_1.1.txt' file, which has instructions on upgrading.
