AI Summary

This release focuses on improving text geometry, specifically superscript and subscript handling, and enhancing PDF loading capabilities. It also introduces new metadata for rotation and bounds, alongside performance optimizations for CI and release processes.

Key Highlights

Improved text geometry handling for superscripts, subscripts, and rotated text.
Enhanced PDF loading with cross-reference table repair and bounded decompression.
New metadata support for baseline, rotation, and embedded bold-font recovery.
Performance improvements in CI and release publishing workflows.

Breaking Changes

Positioned items and region APIs now use the visible page box; manual CropBox-origin adjustments are required.
Rust `TextItem` literals now require `baseline_shift`, `rotation`, and `advance_known` fields.

New Features

Bounded object-stream decompression
Password-aware Python fixture tests
Python binding tests in CI
Positions and regions relative to the visible page box
Rotated-text bounds and rotation metadata
Embedded bold-font metadata recovery
Repair classic cross-reference tables with short entries

Full Release Notes

## Migration

- Positioned items and region APIs now use the visible page box. Remove any manual CropBox-origin adjustment; positioned items use a lower-left origin, while region inputs use a top-left origin.
- Rust `TextItem` literals must add `baseline_shift`, `rotation`, and `advance_known` (`0.0`, `0.0`, and `true` for ordinary upright text).
