+# Release notes for 0.15
+
+This release should be fully backward compatible so the upgrade should require
+no changes.
+
+## Greedy repetitions
+
+The most important new feature in this release is a support for greedy
+repetition. Read more in [the docs](../../grammar_language/#greedy-repetitions).
+
+## New way to disambiguate the GLR forest
+
+A new and recommended way for dynamic disambiguation is by using
+`forest.disambiguate`. Read more in [the docs](../../disambiguation/#disambiguation-of-a-glr-forest).
+
+## Optimized getting of the first tree from the GLR forest
+
+If you are not interested into analyzing the forest and comparing trees but just
+want to get any valid tree you can use `forest.get_first_tree()` which is
+optimized to avoid tree enumeration that might be costly. The returned tree is
+fully unpacked and doesn't use proxies, i.e. it contains only `NodeTerm` and
+`NodeNonTerm` instances.
