4.0.0

• the library doesn't set session.cookie_lifetime to 0 anymore but to the number of seconds specified in the constructor; with this, finally, sessions can be kept alive even if the browser is closed - this fixes #40 and #5
• the library is not setting gc_probability and gc_divisor properties anymore - this can potentially break your code when updating, as there are now less arguments in the constructor method!
• the library does not set session.use_strict_mode anymore - see #37
• updated documentation regarding what configuration options are set automatically
• lots of minor bug fixes and source code formatting because we are now using PHPStan for static code analysis and PHP CodeSniffer for detecting coding standards violations, which are now PSR12-ish with a few of the rules excluded

3.1.0

• fixed a bug where sessions became unusable if the user agent was changed after initialization; thanks to poisons77 for the feedback - see #32

3.0.0

• added integration with PDO
• implemented prepared statemets as mysqli_real_escape_string may not be secure enough when used with PHP < 5.7.6; see this for more information; thanks duckboy81 for suggesting
• sessions can now be started in read-only mode thus not having to do row locks; see #26; thanks more7dev!
• session.use_strict_mode is now always enabled by the library automatically; thanks dnanusevski for suggesting
• session.cookie_secure is now automatically enabled by the library if HTTPS connection is detected; thanks dnanusevski for suggesting
• fixed issue when using special characters in table name; see #27; thanks more7dev!
• added option for disabling automatically starting the session; see #28; thanks Nick Muerdter for the pull request!
