+
+ * eptex.ech: Revise \lastnodesubtype to show math "noad" types,
+ because \lastnodetype returns 15 for all math "noads".
+ * pdfutils.ch: Add \vadjust pre (by Hironobu Yamashita).
+ * eptex.ech, eptex_version.h: e-pTeX version 210701.
+ * tests/lastnodesubtype_math.tex: Added.
+
2021-06-29 Hironori Kitagawa <h_kitagawa2001@yahoo.co.jp>
* eptex.defines: Add fromUCS().
