queXF 1.18.0 has been released today on Sourceforge
Multiple bug fixes and better handling of scanned pages of varying sizes. This release makes the "Page setup" feature optional instead of required. In most cases - this is ideal as using automatic edge detection works better on differing page sizes.
Read on for details of how to upgrade (small database change required).
To upgrade (from queXF 1.17.0)
1. Backup config.inc.php (copy to config.inc.php.bak)
2. Backup your database
3. Update the database:
ALTER TABLE `pages` ADD `usepagesetup` TINYINT( 1 ) NOT NULL DEFAULT '0' AFTER `BR_HORI_BRY`;
4. Extract the new package over your existing installation
5. Copy your config.inc.php.bak file over the extracted config file
