 * `delphin.util.LookaheadIterator` for parsing with arbitrary lookahead

+  - `Relations.path()` returns a path of `(table, shared_field)` tuples
+    describing how to get from one table to another via shared keys
+  - `TestSuite.write()` takes an optional `relations` parameter to write
+    a profile with an updated relations file (#150)
+  - `TestSuite.exists()` (#150)

+  - `select_rows()` takes a `cast` parameter as with `Record.get()`
 
 ### Changed
 
 * `delphin.tdl` now parses triple-quoted docstrings (#167); note that it
   no longer parses the old-style docstrings
 * `delphin.tdl.TdlDefinition` inherits from `delphin.tfs.FeatureStructure`
+* `delphin.itsdb.TestSuite` no longer casts values by default (see note on
+  `Record.get()` above)
+* `delphin.itsdb.TestSuite.process()` can take a `Table` as the `source`
+  instead of just `TestSuite`.
+* **BREAKING** The `delphin` commands have all replaced the previous
+  method of filtering testsuites with the new TSQL queries. Applicators
+  are no longer available to commands. Please see `delphin <cmd> -h` for
+  updated usage notes. (#138, #179)
