 # CloudEvents SQL Expression Language - Version 1.0
 
-See the [CESQL specification](spec.md).
+CloudEvents SQL expressions (also known as CESQL) allow computing values and
+matching of CloudEvent attributes against complex expressions that lean on the
+syntax of Structured Query Language (SQL) `WHERE` clauses.
+
+For more information, see the [CESQL specification](spec.md).

-## vX.Y.Z - YYYY/MM/DD
-- None yet (#000)
+## v1.0.0 - 2024/06/13
+This is the v1 release of the specification! CESQL v1 provides users with the
+ability to write and execute queries against CloudEvents. This allows for
+computing values and matchins of CloudEvent attributes against complex
+expressions that lean on the syntax of Structured Query Language (SQL).
+
+Notable changes between the WIP draft and the v1 specification are:
+- Specify error types
+- Clarify return values of expressions that encounter errors
+- Clarify that missing attributes result in an error and the expression
+  returning it's default value
+- Add support for boolean to integer and integer to boolean type casting
+- Clarify the order of operations
+- Clarify how user defined functions work
+- Define the default "zero" values for the built in types
+- Clarify that string comparisons are case sensitive
+- Specify which characters are treated as whitespace for the TRIM function
+- Specify that functions must still return values along with errors, as well as
+  the behaviour when user defined function do not do this correctly
+- For the fail fast error handling mode, expressions now return the zero value
+  for their return type when they encounter an error, rather than undefined
