# 0.0.2 - 4 Feb 2025

Feature:
33
- support integer, bigint, date, datetime
4+
- support `default` value for optional, and nullable on primitive type
5+
6+
Improvement:
7+
- refactor properties instruction generation
8+
- flatten optional properties to speed up runtime performance in Bun
9+
- remove negate where possible in runtime
10+
- use stringified null to prevent `toString()` call
11+
12+
Bug fix:
13+
- `integer` is using `JSON.stringify`
