It's not actively tested, but my assumption is that every version since 4.1 would work with mysqlnd. When using libmysql connecting to 3.x should work eventually.  From an Oracle perspective 5.5, 5.6 and 5.7 are in active (premier/Extended) support. Older versions (5.0, 5.1) are only in Sustaining Support.  See https://www.mysql.com/support/  https://www.mysql.com/support/supported platforms/database.html and https://www.mysql.com/support/eol-notice.ht ml I would suggest to keep 5.5 and newer active. (I haven't checked, but think there is little to gain from dropping 5.5 on PHP's side) If the community decides to drop support for older versions I'm happy to clean up the code a bit. johannes
