+Changes in version 1.051
+1. Corrected the declaration of the brace extension glyph, so that a number of horizontally extendable math constructions now work properly.
+2. Updated documentation.
 
 Changes in version 1.05
 1. Brought newtxsf into conformance with newtxmath 1.5. New options upint (for an upright integral) smallerops (for smaller large operators).
