Release Notes

(English only)

Jacksum 1.7.0 Linux File Browser Integration 1.3.0, March 12, 2016
- changed sh to bash
- added "Jacksum File Browser Integration" for Xfe (Xfe 1.35+ required), Nemo and Caja
- minor bug fixed: missing optional Thunar xml file could break the installer script
- minor bug fixed: Gnome Nautilus changed script file location on Ubuntu 14.04 and later

Jacksum 1.7.0 Mac OS X Finder Integration 1.1.1, February 28, 2016
- fixed regression that breaks osacompile on AppleScript 1.x
- script now works with all Mac OS X releases starting with 10.2 until 10.11
- installer app requires Mac OS X 10.7 or later

Jacksum 1.7.0 Windows Explorer Integration 1.4.0, February 28, 2016
- Jacksum logo as full featured, multiple icon resource for both the installer
  and the Jacksum SendTo-shortcuts
- script returns error message/instructions if the installation path
  of the JRE has changed since the Jacksum FBI installation (usually that
  happens after a JRE update)
- execution level request of the installer has been set to user in order
  to avoid the UAC which is not necessary for this installer actually
- 64 bit support for the installation: on Windows x64 you can have
  both a 32 bit JRE and/or a 64 bit JRE installed. By default the installer
  searches for the 32 bit JRE first and if a 32 bit JRE is not found it
  continues to search for the 64 bit JRE in order to run Jacksum.
  With the /64 option you tell the installer to search for the 64 bit
  JRE only.
- after the installation the user will have the option to reduce the number
  of items in the SendTo folder
- Installer has been build with NSIS 2.50

Jacksum 1.7.0 Mac OS X Finder Integration 1.1.0, February 13, 2016
- by default the script folder of the user will be used and if the installer
  has been started using root permissions, the system script folder will be
  used
- script wrapped into an .app using Platypus 5.0; the .app requires
  Mac OS X 10.7 or later, the script itself requires Mac OS X 10.4 or later
- improved message/instructions after the installation
- a nice icon for the installer .app

Jacksum 1.7.0 Linux File Browser Integration 1.2.1, November 11, 2011

- redirecting both stdout and stderr to /dev/null in order to avoid
  ugly warnings from Nautilus after a restart of Nautilus

Jacksum 1.7.0, July 30, 2006
- added a customizable CRC algorithm, now you can calculate any CRC which
  can be described by the Rocksoft Model CRC Algorithm (8 to 64 bit width),
  see also sf# 1518023 Setting of an initial value for a CRC
- support for combinable checksums, see also sf# 1210489
  (multiple hashes at the same time), thanks to synonymous2 for this feature request
- support for using all algorithms at once (-a all)
- two new algorithms are supported: crc32_bzip2, HAS-160
- support for Tiger Tree hashes (aka Merkle Hashes). Thanks to Carsten Krüger,
  Germany for the feature request and pointers to some resources
- support for new encodings (bin, dec, oct)
- support for the combination of both options -c and -w,
  Thanks to Dipl.-Inf. (FH) Ralf Kahrl, Germany for the implementation of this feature
- a small performance improvement for the whirlpool algorithms
- replaced the crc24 with a faster one by using the customizable CRC algorithm
  (the old one had also a minor bug in the parameterless constructor)
- bug fixed: -V summary does not always return reasonable values
- bug fixed: update(byte[], int, int) fails if offset is > 0 (sf # 1525183)
  This can cause problems if Jacksum is incorporated in different projects
- The bouncycastle and gnu classes have been moved to jonelo.jacksum.adapt so that
  they won't clash with different downloaded versions of the classes. Actually this
  is to avoid potential problems if a project uses both bouncycastle and Jacksum for example.
  Thanks to Alberto Rodriguez, Spain for the feature request
- documentation updated (BeOS' data integrity programs, Tru64 and year of the invention for
  many algorithms)

  not been created by Jacksum (or a file list without meta information)
  Thanks to Sebastian J., Germany for this feature request
- new option -w for setting the working directory
- new algorithm-code called "none" for ignoring the real content of
  the files for being able to check just against the filesize
- new algorithm-code called "read" for being able to read the file's content,
  but without doing any calculation

  Base 64 and BubbleBabble are supported)
- new option -g (group some bytes) for better readability of a hex checksum

  number of read errors and elapsed time)
- improved option -e: works also for multiple files and directories
  for being able to find duplicates
- improved option -e: when using -e, the option -x is not necessary anymore,
  if the return value by default is hex anyway
- improved option -m: unnecessary defaults are not be written to the header anymore
- improved option -h: can show only fractions of the help file rather than
  the complete help file

  Thanks to Claudio C., Italy for the feature request
- improved option -F: #FILENAME{NAME} and #FILENAME{PATH} can be used
  Thanks to Claudio C., Italy for the feature request

  last character is a colon (e. g. "Terminal 1:")
- improved documentation, added also collision files
