gscan2pdf v1.3.7 released

[Jeffrey Ratcliffe <jeffrey ratcliffe gmail com>]

gscan2pdf - A GUI to produce a multipage PDF or DjVu from a scan.

http://gscan2pdf.sourceforge.net/

Five clicks are required to scan several pages and then save all or
a selection as a PDF or DjVu file, including metadata if required.

gscan2pdf can control regular or sheet-fed (ADF) scanners with SANE via
libsane-perl, scanimage or scanadf, and can scan multiple pages at
once. It presents a thumbnail view of scanned pages, and permits simple
operations such as cropping, rotating and deleting pages.

OCR can be used to recognise text in the scans, and the output
embedded in the PDF or DjVu.

PDF conversion is done by PDF::API2.

The resulting document may be saved as a PDF, DjVu, multipage TIFF file,
or single page image file.

Changelog for 1.3.7:
* Fixed check that pages have been saved
* Fixed scan->rotate->unpaper->OCR chaining (again). Closes:
   bug #213 (Cant call method freeze on an undefined value)
   bug #215 (thanks to Alastair for testing)
* Filter out memory address from unpaper warning. Closes bug #205
  (Gscan2pdf problem with unpaper 6.2) and Debian bug #807565
  (Unpaper error dialog cannot be hidden permanently)
* Ensure that process numbering is properly reinitialised when queue is empty.
* Fixed error importing PDF with more than 999 pages. However, this exposed the
  problem that each page is held as an open temporary file and that the system
  can run out of file handles somewhere after 1000.
