db_last_error.php not included in the beta 3 package?

Just spend some more time trying to understand why  my test upgrade from 2.0 to 2.1 beta did not work:
I got stuck in the install screen with FTP logon.

Finally I figured out that the problem was that file: db_last_error.php was not writable.
Not so strange since this file does not exist in 2.0 (is part of settings.php) and is new to 2.1

Also states so in the wiki:

$db_last_error[edit]
Version: SMF 1.0+
Default value: (not set)
A variable, which stores the Timestamp of the last database connection error. This is not really a setting (and isn't set by default), but merely an internally used variable to prevent multiple emails from being sent after a connection error. See also the $db_error_send setting. As of 2.1 this has been moved to its own file db_last_error.php and is no longer in the Settings.php file.

This being the case would including this (blank) file in the 2.1 packages (upgrade) not be a good idea?

I had the same issue with a brand new SMF 2.1 Beta 3 install - workaround was to create the two required files (Settings_bak.php and db_last_error.php) in same folder as Settings.php  and set the permissions to 755.

the wiki has not been updated to include a lot of the changes in SMF 2.1 as it is still in beta and things can change still. the team will need to look into this a bit further.

Understood. This change was already documented though. That helped me finding the cause of missing the file.   

Everyone upgrading from 2.0 will run into this eventually, so better make this requirement clear in the upgrade process, of even better: make sure the upgrade takes care of this.
