 Release Notes
 =============
 
+2.1.0
+-----
+
+This release restores and improves support for building and running
+multiplatform pexes. Foreign `linux*` platform builds now include
+`manylinux2014` compatible wheels by default and foreign CPython pexes now
+resolve `abi3` wheels correctly. In addition, error messages at both buildtime
+and runtime related to resolution of dependencies are more informative.
+
+Pex 2.1.0 should be considered the first Pex 2-series release that fully
+replaces and improves upon Pex 1-series functionality.
