- Corrected an issue in which fonts could be embedded with a substitute font when a font reference is not found as a system resource.

- PDF Optimizer Includes latest version of the PDF Checker tool.
- For Windows, the PDF Optimizer installer includes an option to subsequently run the PDF Checker installer.

- The transparency quality settings have been adjusted to more appropriate values for high, medium, and low-quality output.
- Improved merging of font subsets when the PDSaveOptimizeFonts flag is used.
- PDF Optimizer now by default first looks for the profile in the installation directory. If the product cannot find that profile file there, it looks at the command line statement, and treats the profile included there as the path to the profile file.
- Application and installer are now signed with the certificate from Datalogics.
- Specific error added for when the user is unable to save output results to the output file specified.
- Changed default installation directory to “Program Files/Datalogics/ PDFOptimizer.”
- Added a new process that looks for situations that would require incremental saves for an export PDF document, such as a signed PDF document or a need to include usage rights. The process ends with an error message, rather than continuing to process the optimization.
- Added optimization for 16-bit per channel (bpc) J2K images (a compression format for JPEG image files) and applies subsampling to JPEG compression.
- Added new option “write-output-even-if-increase-in-size” that can be used to decide whether to keep outputs when they cannot be reduced in size.

- Corrected a problem with optimization in which text could become damaged when subsetting Type1 fonts with a custom encoding.
- Corrected a problem where reading Images category flags would not always be honored.
