ETIS Framework v1.4.0 — Books and Professional Computing Series

Summary

ETIS Framework v1.4.0 expands the public ETIS publishing architecture while preserving Engineering Trustworthy Intelligent Systems as the foundational ETIS Framework Reference Work.

This release establishes a durable long-form publishing model alongside the existing ETIS Publications Program.

Major Changes

ETIS Books Architecture

• Added the ETIS Books landing architecture.
• Established Engineering Trustworthy Intelligent Systems as the ETIS Framework Reference Work.
• Clarified the ETIS Two-Volume Professional Edition as the integrated two-volume publishing form of the Framework Reference Work.
• Added the ETIS Professional Computing Series.
• Added From Data Structures to Engineering Judgment: Professional Computing in the AI Era as the inaugural Professional Computing Series title.
• Added book overview, companion-resource, and updates/errata architecture.

Ecosystem Integration

• Integrated Books across the ETIS website and publishing architecture.
• Updated Downloads to support both Framework Reference Work and Professional Computing Series titles.
• Aligned Publications, Education, Engineering Platform, About, Author, First Edition, Legal, and homepage terminology.
• Preserved Books and Publications as distinct peer publishing forms.
• Preserved the ETIS Publications Program as the canonical home for White Papers, Executive Briefs, and Education Papers.
• Preserved the Engineering Platform as the practical implementation environment for applying ETIS.

Repository and Governance

• Updated root repository documentation, roadmap, changelog, license, and security scope.
• Updated citation and release metadata for v1.4.0.
• Clarified the distinction among framework doctrine, professional computing books, focused publications, educational products, and implementation resources.
• Refined cross-site terminology and internal navigation relationships.

Publishing Architecture

The ETIS publishing ecosystem now distinguishes:

• ETIS Framework Reference Work — comprehensive ETIS doctrine and full-lifecycle treatment.
• ETIS Two-Volume Professional Edition — two-volume publishing form of the integrated Framework Reference Work.
• ETIS Professional Computing Series — sustained professional-computing works aligned with ETIS.
• ETIS Publications Program — focused, citable White Papers, Executive Briefs, and Education Papers.

Validation

The website and repository documentation were reviewed for navigation consistency, MkDocs link behavior, publishing terminology, and cross-site alignment.

This release represents a publishing-architecture expansion rather than a new edition of the ETIS Framework doctrine.
