+Three options have been added to control the space to the left of
+\env{aligned} and \env{gathered} environments. Prior to the 2017 release
+a thin space was added to the left but not the right of these constructs.
+This appears to have been an accidental feature of the implementation and
+was typically corrected by prefixing the environments with \cn{\!}.
+
+The new default behavior is aimed to ensure that the environments do
+not have a thin space added in most cases, and that existing documents
+using |\!\begin{aligned}| continue to work as before.

+\begin{description}
+\item[\opt{alignedleftspaceyes}] Always add \cn{\,} to the left of \env{aligned} and \env{gathered}.
+\item[\opt{alignedleftspaceno}] Never add \cn{\,} to the left of \env{aligned} and \env{gathered}.
+\item[\opt{alignedleftspaceyesifneg}] Only add \cn{\,} if the environment is prefixed by negative space. (New default behavior.)
