Chess Material Studio v2.7.0

Chess Material Studio v2.7.0

Highlights

• Added a validated PGN review workflow with chapter-scoped saved PGN positions.
• Saved PGN positions can be persisted, reopened, deleted, and exported separately from puzzle material.
• Active-chapter saved PGN positions can be exported as PGN games beginning at the saved board and continuing the remaining stored main line.
• Improved PDF solution layout with width-aware wrapping and continuation across pages.

Reliability and maintenance

• PGN exports now use safer atomic publication.
• Normal PDF exports reject invalid page limits before touching the destination.
• Runtime resources resolve independently from the process working directory.
• Search batches reject stale results after source changes.
• UCI analysis rejects stale evaluations from prior positions.
• PGN parsing and session construction run off the UI update path.
• PGN terminal results are preserved and contradictory header/movetext results are rejected.
• CI and dependency-security maintenance were strengthened with pinned actions, Dependabot, and RustSec auditing.

Platforms

Release archives are provided for:

• Linux
• macOS
• Windows x86_64
• Windows i686

Scope note

Saved PGN-position export in v2.7.0 is available for the active chapter. Project-wide, selected-chapter, and PDF export of saved PGN positions are not included. PGN comments, variations, and NAGs are not preserved by the current minimal PGN model.
