ozzo-validation Files

Revival release — ozzo-validation is actively maintained again after 6 years.

12 community PRs merged, maintainer bug fixes, modernized CI infrastructure.

Added

• is.UUIDv7 validation rule per RFC 9562 (#205 by @dmitryzhvinklis)
• is.ULID validation rule (#171 by @upamune)
• is.Origin validation rule for CORS origins (#198 by @nguyenvantuan2391996)
• OptionalKey() and DynamicMap() convenience constructors (#151 by @Jessinra)
• EachUntilFirstError() rule for large collections (#93 by @geekflyer)
• GitHub Actions CI, golangci-lint, Codecov (99.5% coverage), benchmark infrastructure

Fixed

• E.164 phone validation now requires + prefix per ITU-T standard (#208 by @Yanhu007)
• Domain regex allows uppercase in final character (#197 by @mhargrove)
• Each() now passes pointers correctly to By() callbacks (#160 by @dane)
• IsEmpty() treats all zero-valued structs as empty (#144 by @soranoba)
• Errors.Error() no longer panics on nil values (#212)
• Min()/Max() now validate zero values instead of silently skipping them (#212)
• README install command, code examples, documentation

Breaking Changes

These are bug fixes — the old behavior was incorrect:

• is.E164 rejects phone numbers without + prefix (spec-correct)
• Each() with By() on pointer slices passes *T instead of T
• IsEmpty() returns true for zero-valued structs (was only time.Time{})
• Min()/Max() validate numeric zero and time.Time{} (were silently skipped)

Thank You

Thanks to all contributors who waited patiently — some PRs were open for 5+ years. Special thanks to @qiangxue for entrusting the project to new maintainers.
