Download

Install the ZIP matching the operating system, architecture, and CPython ABI
used by Sigil's plugin process. The Fat Plugin covers the five CPython
3.14/cp314 targets; Linux x86_64 with CPython 3.12/cp312 has its own platform
package.

Asset	Runtime coverage
Fat Plugin	Linux aarch64/x86_64, macOS arm64/x86_64, and Windows x86_64; CPython 3.14/cp314
macOS arm64	Apple Silicon; CPython 3.14/cp314
macOS x86_64	Intel or Rosetta; CPython 3.14/cp314
Windows x86_64	Windows x64; CPython 3.14/cp314
Linux x86_64	CPython 3.14/cp314
Linux x86_64 cp312	CPython 3.12/cp312, including Ubuntu 24.04's packaged Sigil

Changes

• Add versioned rules with protect, final-wording, pre-replacement, and
  post-replacement actions, using literal or regular-expression matching.
• Bundle the pinned regex engine for all six supported runtime targets. Regex
  rules run offline with time, hit-count, output-size, and zero-length guards.
• Add templates for author-credit protection, marker-delimited protection,
  contextual replacement, and horizontal-space cleanup.
• Use one conversion pipeline for the rule sandbox and book conversion. Changes
  map back to original XHTML locations, and dependent edits stay grouped.

Automated validation

The tagged release workflow validates the six runtime identities, builds the
Fat Plugin and six platform ZIPs, runs package smoke tests on all targets,
verifies SHA-256 checksums, and attests every release asset before publishing.
The ZIPs include the multilingual rule guide and third-party notices.

Remaining acceptance

Installation, conversion, save, and reopen have not been tested in a real
Sigil host. Host acceptance remains Not verified.
