+## Version Management
+
+**CRITICAL**: When creating a new branch or PR from main, ALWAYS increment the development version number in the DESCRIPTION file to one version past the current main branch version.
+
+For example:
+- If main branch has version `0.0.0.9005`
+- Your new branch MUST have version `0.0.0.9006`
+
+This ensures that package versions remain unique across branches and prevents version conflicts.
+
+**Before finishing each coding session**: Fetch the main branch and increment the development version if your branch is not ahead of main, before committing and requesting review again.
+

 # rpt (development version)
 
+* Added DOCX (Word document) format for Quarto vignettes and articles in pkgdown documentation, alongside existing RevealJS format. HTML pages now display an "Other Formats" section with links to both slide and Word document versions
+  * Fixed rendering issue by rendering each format separately instead of using "all" to avoid hanging
+  * Conditionally excluded Mermaid diagrams from DOCX format using `.content-visible unless-format="docx"` (Mermaid diagrams remain in HTML and RevealJS outputs)
 * Updated lintr configuration to match serodynamics reference with enhanced linter rules
 * PR preview comments now use `recreate: true` to ensure they always appear at the bottom of the PR conversation, preventing them from being hidden in collapsed sections (#31)
