Hello

A new version of the data recovery utilities TestDisk & PhotoRec has been 
released at http://www.cgsecurity.org/wiki/TestDisk_Download

This new version brings some security fixes, a GUI for PhotoRec, a faster 
PhotoRec, less false positives...

== General Improvements ==
Various fix including security fix, thanks to
* Coverity scan (Static Analysis of source code)
* afl-fuzz (security-oriented fuzzer).
* Denis Andzakovic from Security Assessment for reporting an exploitable 
Stack Buffer Overflow

== TestDisk ==
=== Improvements ===
* exFAT: better support
* ext4: handle 64 bit blocks or 64 KiB blocksize. Fix detection and file 
listing

=== Bug fixes ===
* Avoid erroneous error when writing 512 bytes on hard disk using 4k 
sector
* FAT, NTFS: avoid NULL pointer dereference if localtime() returns NULL. 
Thanks to Graham Sutherland for reporting this bug.

== PhotoRec & QPhotoRec ==
QPhotoRec is a Graphical User Interface (Qt based GUI) version of 
PhotoRec. More user friendly, it recognizes the same file formats.

PhotoRec remains recommended for advanced users, it can stop a recovery 
and resume it later, it recovers more fragmented files when brute-force 
technology is enabled and expert mode is available.

=== Improvements ===
* Reduced false positives for more than 80 file formats.
* .gif: fix filesize detection
* .flv: add Flash filesize detection
* .mpg: detect filesize for MPEG
* .ra: detect filesize for RealAudio3
* Improved algorithm to deal with data fragmentation resulting in a 
general speed increased
* Speedup brute-force mode. Brute-force mode can recover more fragmented 
files, but it's still slow and not 100% reliable. You can enable it in 
PhotoRec Options menu.

New file formats recovered by PhotoRec:
* .3dm: Rhino / openNURBS
* .ari: ARRI Raw Video
* .camrec: Camtasia Studio
* .dad: Micae DVR
* .dcm: Digital Imaging and Communications in Medicine (DICOM)
* .fp12: File Maker Pro 12
* .kra: Krita
* .mlv: Magic Lantern Video
* .notebook: SMART notebook
* .ora: Mypaint
* .red: RED2 video format
* .rlv: Revelation password
* .vbm: Veeam Backup Metadata
* .woff: Web Open Font Format

Regards,

 	Christophe

PS: Some antivirus like Avira erroneously reports a trojan when scanning 
the win32 version of TestDisk 7.0. Hope they fixes their virus 
databases...
