v0.3.0-alpha

This is a major version release and contains a few backward-incompatible changes to the ExprNode and ParitqlAst APIs.
New features of this version:

• DATE and TIME data types
• Enhancements made by/for DynamoDB:
  • Parser support for:
    • Multiple SET, REMOVE operations per DML statement.
    • The ON CONFLICT DML clause was added.
    • The RETURNING DML clause was added.
    • ORDER BY clause was added (NOTE: ORDER BY can be parsed, however evaluator support has not been added yet).
    • A redact function has been added that removes potentially sensitive information from SQL queries, allowing them to be logged for later analysis.
• Compile-time Thread.interrupted() checks were added to help mitigate the impact of compiling extremely large SQL queries.
• Various performance improvements to the compiler were added.

Bug fixes:

• Fixes parser for the top level tokens (#369)
• Make SIZE function work with s-expressions. (#379)
• A number of other minor bug fixes and technical debt has been addressed. For a complete list of PRs that made it into this release, please see the v0.3.0 GitHub milestone.

Backward incompatible changes:

• The modeling of ExprNode and PartiqlAst APIs has changed as needed to account for the enhancements to DML statements and ORDER BY. Customers using these APIs may be affected.
• Other minor API changes. See the attached compat-report-0.2.6-to-0.3.0.html file for further details.
