+# 0.1.27
+
+* Context is now added to each returned component in `query->components`. E.g., instead of `#{"foo" "bar"}`, it will
+  return its elements as `#{{:component "foo" :context ["SELECT"]}, {:component "bar" :context ["WHERE" "SELECT"]}}`
+
+* `has-wildcard` now returns a set of such maps. For example:
+
+```
+(query->components (parsed-query "SELECT * FROM (SELECT * FROM orders) WHERE total > 10"))
+; =>
+{ ...
+  :has-wildcard?
+  #{{:component true, :context ["SELECT" "SUB_SELECT" "FROM" "SELECT"]}
+    {:component true, :context ["SELECT"]}}}
+```
+
+* The context stack can be counter-intuitive. For example, in the above query, the context stack for the `"total"`
+  column from the `WHERE` clauses is `["WHERE" "JOIN" "FROM" "SELECT"]`. The vector is arranged from most- to
+  least-specific. For most cases you probably only want to look at the first element and/or make assertions about the
+  relative order of multiple elements.

+
+* (The project was young enough not to merit a changelog. Refer to other documentation)
