Changelog summary: Major version bump spanning 13 releases. v9.0.0 adds PDF editor
API, macro recording, Service Worker caching. v9.2.1 fixes critical security vulns
(XSS, memory manipulation leading to RCE in XLS conversion). v9.3.0 adds GIF animations,
multiple pages view, signature settings, hyperlinks on images/shapes.
Risk: CAUTION (major version bump 8->9)
Breaking changes: none affecting Docker+MySQL deployment. PostgreSQL schema change
in v9.0.0 (irrelevant — we use MySQL). API endpoint deprecations (ConvertService.ashx,
GET requests to converter/command) — not removals. Config parameter renames
(leftMenu->layout.leftMenu etc.) are editor JS API, not server config.

Config changes applied: none required
Flagged for manual review: none
