+0.79.10.patchlevel-1 09-10-2021 *UNOFFICIAL*
+- sync: integrated changes from latest upstream,
+        please refer to the entries below for details.
+
+0.79.10 24-09-2021
+ - command line only version can be generated by
+   using ./configure --with-gui=no
+   The cli version will not be linked against gtk+ and it auxiliary libs.
+   However, glib is still required as it provides some basic functionality
+   for multithreading and string operations.
+ - Fixed a checksum buffering bug which was introduced in 0.79.6:
+   If user reads in CD A, then switches to image of CD B in the file dialogue
+   and creates error correction data, depending on the codec some invalid
+   checksums from CD A will be drawn into the ecc data for CD B. 
+ - Fixed crc buf related memory leak while reading/scanning
+ - run_regtest will now insist that both image and ecc arguments are given.
+   This prevents stale arguments when running in GUI mode.
+ - Test case motivated changes/fixes:
+   - in general: fixed missing/inappropriate parameters in test cases for GUI mode
+   - RS01_scan_tao_tail_with_ecc
+     corrected wording of warning message (scan mode won't alter the image)
+   - RS01_scan_medium_with_dsm
+     RS01_read_medium_with_dsm 
+     substantiated reading summary
+   - RS01_read_medium_with_dsm_in_image
+     removed reporting of displaced sectors in the image (only displaced
+     sectors in the medium matter!)
+   - RS02_ecc_recreate_after_read_rs02
+     crc buf now considered valid (when stripping the data portion from
+     the read image)
+   - RS03i_plus_56_bytes
+     RS03i_with_ecc_file_header
+     fixed misconfiguration of testcase for GUI
+   - RS03i_missing_header (and most following verify tests)
+     prognosis would declare image as uncorrectable because treatment
+     of unreadable ECC headers was broken.
+   - RS03i_missing_header3/4
+     Test case created an uncorrectable image (which did test the required
+     properties, though). Changed to a test-equvalent correctable image.
+   - RS03f_ecc_recreate_after_read_rs02
+     rs03-create.c:prepare_header() called CrcBufValid() with wrong values when
+     creating error correction files for an already augmented image.
+  - Merged fixes from Stéphane Lesimple's version
+   - printf argument debugging and PRId64 etc. format strings
+   - -Werror setting
+   - "easy" patches; non-trivial changes have been noted and
+      will be processed later
+   - Merged Debian patches:
+     08 gmake detection
+     10 dvdisaster.desktop
+     12 up to spelling
+     17 API warnings (partially merged)
+     29 fix more typos
+     33 - obsoleted -
+     34 format security warning
+     35 archived homepage (rewritten with references to the pdf manuals)
+

 0.79.9 14-05-2021
 - Revised code for clean compile under gcc-10 and Debian 11 (sid) or Slackware 15
 - added -Wno-deprecated-declarations to shield against a flood of warnings
@@ -159,8 +217,6 @@
   amending the source files to make the CLI-only version possible.
   This hopefully removes a few quirks without adding too many.

 0.79.6 20-11-2017
 - The Verify/Test option will now output dvdisaster version
