   31. `on=.()` syntax is now posible, e.g., `X[Y, on=.(x==a, y==b)]`, [#1257](https://github.com/Rdatatable/data.table/issues/1257). Thanks @dselivanov.
 
+  32. Non-equi joins are now possible using the familiar `on=` syntax. With this, the set of binary operators extend from just `==` to `>=`, `>`, `<=`, `<` and `==`. For e.g., `X[Y, on=.(a, b>b)]` looks for `X.a == Y.a` first and within those matching rows for rows where`X.b > Y.b`. Partly addreses [#1452](https://github.com/Rdatatable/data.table/issues/1452).
