 ### Changed
+- **removing Tracer class from sqlite-parser until a faster solution is developed**
+  - Tracer is causing a **14x performance hit** to the sqlite-parser specs when it is enabled
+  - might consider having two different builds: one _smart error_ build with Tracer and another _performance_ build for speed
 - fixed rules for `WITH` clause prepended to CRUD-type statements to make sure the `with` property is added to the correct nodes
 - changed the AST for `WITH` clause to no longer have a node of `type` `"with"`
 
@@ -88,6 +93,7 @@ All notable changes to this project will be documented in this file.
 - several property values are now being normalized to lowercased strings instead of being passed unmodified to the AST. for example, the `action` property of `action` node now contains a lowercased value.
 - removed redundant rules that pointed to `name` rule, such as `name_function`, `name_view`, and `name_trigger`.
 - unquoted identifiers are now normalized to lowercased strings as per the SQL-92 standard. quoted identifiers are not normalized.
+- SQLite functions are now normalized to lowercase strings in the output AST.
 - now preventing FOUC when first loading the demo page. also allowing cursor focus on "Syntax Tree" editor so that the contents can be selected and copied to the clipboard.

-## Syntax Errors
-
-This parser uses the `--trace` flag exposed in `pegjs` to create "smart" error
-messages. The parser includes a `Trace` class that keeps track of which grammar
-rules were being traversed just prior to the error and uses that information
-to improve the error message and location information.

 ## AST
 
 **NOTE: The SQLite AST is a work-in-progress and subject to change.**
