Bug fixes for 4.2.0 force additional interfaces, so move most of the 4.2.0 items to 4.3.0.
-
When copying dlls, make sure to only consider DLLs whose type matches the type of what is loading them.
-
Prepare update for TODO for publication since there is useful information there for people looking at the repository.
-
These object types are to facilitate content stream parsing.
-
Read and write support is implemented for /V=5 with /R=5 as well as /R=6. /R=5 is the deprecated encryption method used by Acrobat IX. /R=6 is the encryption method used by PDF 2.0 from ISO 32000-2.
-
Test cases added in a future commit since they depend on /R=6 support.
-
This replaces a PDF from the wild that I didn't want to include in the test suite but used to verify the original fix.

3.0.rc1
-
Implement --pages ... -- option for qpdf. Update TODO with remaining things to document.
-
Move object parsing code from QPDF to QPDFObjectHandle and parameterize the parts of it that are specific to a QPDF object. Provide a version that can't handle indirect objects and that can be called on an arbitrary string. A side effect of this change is that the offset used when reporting invalid stream length has changed, but since the new value seems like a better value than the old one, the test suite has been updated rather than making the code backward compatible. This only effects the offset reported for invalid streams that lack /Length or have an invalid /Length key. Updated some test code and exmaples to use QPDFObjectHandle::parse. Supporting changes include adding a BufferInputSource constructor that takes a string.
-
Add --copy-encryption and --encryption-file-password options to qpdf. Also strengthen test suite for copying encryption. The strengthened test suite would have caught the failure to preserve AES and the failure to update the file version, which was invalidating the encrypted data.
-
Method to copy encryption parameters from another file. Adapted from existing code to copy encryption parameters from the original file.
-
This includes QPDF::copyForeignObject and supporting foreign objects as arguments to addPage*.
