v0.13.0

A Release Featuring CLI Pipelines and Safer Defaults

Starting with this release, pdfcpu improves CLI usability with broader stdin/stdout pipeline support and stricter overwrite handling.

Check out the refreshed documentation at https://pdfcpu.io

Many commands now support - for stdin/stdout, making pdfcpu easier to use in shell pipelines. Explicit output files and non-empty output directories are no longer overwritten implicitly. Use the new global --force flag when overwriting is intentional.

Example:

pdfcpu optimize - out.pdf < in.pdf

or:

cat in.pdf | pdfcpu optimize - - > out.pdf

or a pipeline:

aws s3 cp s3://acme-contracts/master.pdf - \
      | pdfcpu optimize - - \
      | aws s3 cp - s3://acme-contracts/optimized/master.pdf

CLI Improvements

This release adds and refines several user-facing CLI features:

• Broader stdin/stdout support using -
• Global --force flag for explicit overwrite handling
• annotations list --json
• form list --json
• certificates list --json
• merge --bookmark-mode wrap|preserve
• Improved version command behavior
• Clarified help text around signature validation scope and trust boundaries

The new overwrite behavior is intentionally stricter. Existing scripts that relied on implicit overwrites may need to add --force.
