+# Version 3.0.0 preview 4
+## New Features
+* new command `review-update` is added, which updates the setting of the project files to the new version ([#1144])
+* `texequation` representing an expression can now be numbered and captioned.  To reference this you can use the `@<eq>` operator ([#1167])
+
+## Breaking Changes
+* In IDGXMLBuilder, PlaintextBuilder, and TextBuilder, the expansion result of `@<chapref>` is no longer created in a unique way. Like other builders, it uses the `chapter_quote` locale string ([#1160])
+
+## Bug Fixes
+* samples collection could not generate PDF in preview 3. Now it works with `rake pdf` ([#1156])
+
+## Enhancements
+* PDFMaker: support hiddenfolio parameter with review-jlreq.cls ([#1147])
+* EPUBMaker/WEBMaker: when imgmath function is enabled, font size is passed to each `//texequation` ([#1146])
