 * Added `traverse-all` which returns a transducer that traverses over all elements matching the given path.
 * `select-first` and `select-any` now avoid traversal beyond the first value matched by the path (like when using `ALL`), so they are faster now for those use cases.
 * Add `NAME` and `NAMESPACE` navigators
+* Extend `srange`, `BEGINNING`, `END`, `FIRST`, and `LAST` on strings to navigate to substrings
 * Improved `ALL` performance for PersistentHashSet
 * Dynamic navs automatically compile sequence returns if completely static
 * Eliminate reflection warnings for clj (thanks @mpenet)
