Subject:Upgrade of MySQL FLOSS License Exception
View as plain text  
Greetings All,

Version 0.2 of the MySQL FLOSS License Exception has been released.

The MySQL FLOSS License Exception is an extension to the terms and  
conditions of the GNU General Public License (GPL) that increases the  
compatibility between the GPL and other Free Software and Open Source  
licenses (such as the Apache License, the BSD license and the PHP  

If you distribute software based on the GPL-licensed version of MySQL,  
you may be interested in reading and discussing this exception.

The text of the exception is attached to this document and is published  
online at:
  * (and at

Major changes include:
  * Removal of restrictions that made distribution of MySQL challenging  
for BSD and Linux Distributions
  * Clarifications to the wording of the exception

For more detailed information on the changes made and issues addressed,  

The exception will apply to future MySQL versions 4.0.21, 4.1.4 and  

You can download development versions of the 4.0.x and 4.1.x series  
that include the exception from

The 5.0.x series will have the exception applied as soon as we do a  
code merge between the 4.1.x series and the 5.0.x series.

If you have any questions or comments, please drop me a line! If the  
matter is not private or sensitive, I encourage you to do so on this  
list so that others can benefit from the discussion.

MySQL FLOSS License Exception v0.2

The MySQL AB Exception for Free/Libre and Open Source Software-only
Applications Using MySQL Client Libraries (the "FLOSS Exception").

Exception Intent
We want specified Free/Libre and Open Source Software ("FLOSS") applications
to be able to use specified GPL-licensed MySQL client libraries (the
"Program") despite the fact that not all FLOSS licenses are compatible with
version 2 of the GNU General Public License (the "GPL"). 

Legal Terms and Conditions
As a special exception to the terms and conditions of version 2.0 of the

1. You are free to distribute a Derivative Work that is formed entirely from
   the Program and one or more works (each, a "FLOSS Work") licensed under
   one or more of the licenses listed below in section 2, as long as:

    a. You obey the GPL in all respects for the Program and the Derivative
       Work, except for identifiable sections of the Derivative Work which
       are not derived from the Program, and which can reasonably be
       considered independent and separate works in themselves, 

    b. all identifiable sections of the Derivative Work which are not
       derived from the Program, and which can reasonably be considered
       independent and separate works in themselves,

        (i) are distributed subject to one of the FLOSS licenses listed
            below, and
       (ii) the object code or executable form of those sections are
            accompanied by the complete corresponding machine-readable
            source code for those sections on the same medium and under the
            same FLOSS license as the corresponding object code or
            executable forms of those sections, and

    c. any works which are aggregated with the Program or with a Derivative
       Work on a volume of a storage or distribution medium in accordance
       with the GPL, can reasonably be considered independent and separate
       works in themselves which are not derivatives of either the Program,
       a Derivative Work or a FLOSS Work.

If the above conditions are not met, then the Program may only be copied,
modified, distributed or used under the terms and conditions of the GPL or
another valid licensing option from MySQL AB.

3. Definitions

   a. Terms used, but not defined, herein shall have the meaning provided in
      the GPL.

   b. Derivative Work means a derivative work under copyright law.

4. Applicability

This FLOSS Exception applies to all Programs that contain a notice placed by
MySQL AB saying that the Program may be distributed under the terms of this
FLOSS Exception.  If you create or distribute a work which is a Derivative
Work of both the Program and any other work licensed under the GPL, then
this FLOSS Exception is not available for that work; thus, you must remove
the FLOSS Exception notice from that work and comply with the GPL in all
respects, including by retaining all GPL notices.  You may choose to
redistribute a copy of the Program exclusively under the terms of the GPL by
removing the FLOSS Exception notice from that copy of the Program, provided
that the copy has never been modified by you or any third party.
