General note: Always check cfg.py for changes in the new version. If you
made any changes in that file in the old version, you'll have to re-apply them
to the new cfg.py

1.0.1 -> 1.0.2
--------------
Nothing special needs to be done.


1.0.0 -> 1.0.1
--------------

There was a bug in mysqlUserFolder (when used with Plone) in the 
_doChangeUser (). Upon calling this function, mysqlUserFolder would store
'mysqlRole' into the database (table Roles). Thiw is wrong, if you have this 
role in the table Roles, please remove it. And also remove all records from
UserRoles that reference this role.

0.9.2 -> 1.0.0
--------------
Nothing special needs to be done.


0.9.1 -> 0.9.2
--------------

(1) Parameter REQUEST_RHOST_FIELD is removed. Parameter REQUEST_RADDR_FIELD 
is not used for Zope 2.7 and later.

(2) AUTO_CREATE_ROLES option is added. Value 0 represents the old behaviour.
Value 1 will allow automatic creation of missing roles inside the 
user.change_user_roles () call.


0.9.0 -> 0.9.1
--------------

(1) Password field in the Users table needs to be extended to 32 characters.
This is needed for MD5 passwords.

(2) There was a problem with docLogin method in previous versions. This method
can be shown directly (in this case it needs to generate HTML header/footer)
or in the exception - when protected resource is accessed. In the later case,
docLogin is actually shown through standard_error_message method and this 
method usually includes HTML header/footer. Default version of docLogin method
in previous versions generates invalid HTML when shown in exception. In 0.9.1
mysqlUserFolder will pass a parameter "exception_raised" when it raises
docLogin as exception, so the proper code can be generated. Check all existing
docLogin methods and change them to avoid the problem. Check new default
docLogin method (dtml.user/u_Login.dtml) for hints.

(3) File cfg.py is changed in this version - length of the password field is
now 32.


0.6.4 -> 0.9.0
--------------

(1) New field is added to the Users table. It has to be created for the 0.9.0
version (default value should be '' - it means no domain restrictions):
	
	"Domains char (160) DEFAULT '' NOT NULL"


(2) Cookie and logging parameters are moved from cfg.py to the instance of the
mysql user folder. Backup your old cfg.py, change the parameters in the new
cfg.py, and for each user folder object visit Properties and Parameters tabs.


(3) Security settings for act_* DTML methods (they are used by ordinary users
when they change their data and create new users) are changed. By default,
access will be denied. Read the README file and follow the steps from there
to setup access to these methods for each user folder object.
