-# tidyr 0.7.0.9000
+# tidyr 0.7.1
+
+This is a hotfix release to account for some tidyselect changes in the
+unit tests.
+
+Note that the upcoming version of tidyselect backtracks on some of the
+changes announced for 0.7.0. The special evaluation semantics for
+selection have been changed back to the old behaviour because the new
+rules were causing too much trouble and confusion. From now on data
+expressions (symbols and calls to `:` and `c()`) can refer to both
+registered variables and to objects from the context.
+
+However the semantics for context expressions (any calls other than to
+`:` and `c()`) remain the same. Those expressions are evaluated in the
+context only and cannot refer to registered variables. If you're
+writing functions and refer to contextual objects, it is still a good
+idea to avoid data expressions by following the advice of the 0.7.0
+release notes.

 ## Reverse dependencies
 
-I have run R CMD check on the 268 downstream dependencies. (Summary at
-https://github.com/tidyverse/tidyr/tree/master/revdep).
-
-There were 9 problematic packages. We carefully reviewed each failure
-and determined that they were due to a deliberate backward
-incompatible change to the tidyr API. Authors were notified on August
-1 (two weeks ago) with a suggested fix for the problem.
+I have not run the reverse dependencies since this release is
+identical to the previous one except for a couple of unit tests.
