Feb 1, 2026February 2026 monthly summary focusing on delivering high-value paste fidelity and cross-platform formatting consistency in roosterjs. Key features include filtering temporary End of Paragraph markers during Word Online paste to reduce stray formatting and adding targeted test pattern support; correcting indentation for lists pasted from Word Desktop by subtracting the default 40px margin; and preserving trailing spaces in the last paragraph segment by converting to non-breaking spaces, supported by a new ModelToDomSegmentContext and expanded tests. These initiatives were backed by targeted unit tests, parser enhancements, and test-runner improvements, resulting in more reliable paste workflows and reduced user rework across Word Online and Word Desktop.
