One more notice:
limiting number of queries per hour for different users has been done
on 4.0.1 , but I can port it to 3.23.*
This will require only certain changes, like number of columns in user
table.
I will also make a test case for it, after it is approved by Monty,
as result file will depend on the error message text.
* multi-table updates
* new paid feature for limiting number of queries per hour for users
* optional syntax for multi-table deletes
* optimization for SQL_CALC_FOUND_ROWS
* a small addition for CREATE .. SELECT that will be of future use
I know that all this will require many additions to documentation,
which I have not done, but I am at Arjen's disposal to help him document
all this.
