Package signatures

To ensure the integrity of the libjpeg-turbo binary packages, the RPM and DEB files and the source tarball are signed using the following key:
http://www.libjpeg-turbo.org/key/LJT-GPG-KEY-1024
http://pgp.mit.edu/pks/lookup?op=get&search=0x85C7044E033FDE16
and the Windows installers are signed using a code signing certificate.

Packaging changes

• As of 2014-03-22, Cygwin packages have been moved into a custom repository directory. See http://www.libjpeg-turbo.org/Documentation/Cygwin for more details.
• A Cygwin64 package was added on 2013-10-16.
• A new copy of libjpeg-turbo-1.3.0.dmg was uploaded on 2013-09-24 to address a build issue whereby the ARM v7 and ARM v7s architectures of libjpeg.a and libjpegturbo.a did not include SIMD code.

1.3.0

Significant changes relative to 1.3 beta1:

1. make test now works properly on FreeBSD, and it no longer requires the md5sum executable to be present on other Un*x platforms.

2. Overhauled the packaging system:

   • To avoid conflict with vendor-supplied libjpeg-turbo packages, the official RPMs and DEBs for libjpeg-turbo have been renamed to "libjpeg-turbo-official".
   • The TurboJPEG libraries are now located under /opt/libjpeg-turbo in the official Linux and Mac packages, to avoid conflict with vendor-supplied packages and also to streamline the packaging system.
   • Release packages are now created with the directory structure defined by the configure variables prefix, bindir, libdir, etc. (Un*x) or by the CMAKE_INSTALL_PREFIX variable (Windows.) The exception is that the docs are always located under the system default documentation directory on Un*x and Mac systems, and on Windows, the TurboJPEG DLL is always located in the Windows system directory.
   • To avoid confusion, official libjpeg-turbo packages on Linux/Unix platforms (except for Mac) will always install the 32-bit libraries in /opt/libjpeg-turbo/lib32 and the 64-bit libraries in /opt/libjpeg-turbo/lib64.
   • Fixed an issue whereby, in some cases, the libjpeg-turbo executables on Un*x systems were not properly linking with the shared libraries installed by the same package.
   • Fixed an issue whereby building the "installer" target on Windows when WITH_JAVA=1 would fail if the TurboJPEG JAR had not been previously built.
   • Building the "install" target on Windows now installs files into the same places that the installer does.

3. Fixed a Huffman encoder bug that prevented I/O suspension from working properly.
