Highlights include the complete removal of the unsafe package. go-toml is now fully safe Go code, with a geomean overhead of only \~1.4% vs v2.2.4 and zero additional allocations on benchmarks. This release also adds omitzero struct tag support, improves UnmarshalText/Unmarshaler handling for tables and array tables, and fixes several bugs including nil pointer marshaling, leap second handling, and datetime unmarshaling panics. <!-- Release notes generated using configuration in .github/release.yml at v2.3.0 --> #### What's Changed ##### What's new - marshal: don't escape quotes unnecessarily by [@​virtuald](https://github.com/virtuald) in [#​991](pelletier/go-toml#991) - Add `omitzero` tag support by [@​NathanBaulch](https://github.com/NathanBaulch) in [#​998](pelletier/go-toml#998) - Support custom IsZero() methods with omitzero tag by [@​pelletier](https://github.com/pelletier) in [#​1020](pelletier/go-toml#1020) - UnmarshalText fallbacks to struct unmarshaling for tables and arrays by [@​pelletier](https://github.com/pelletier) in [#​1026](pelletier/go-toml#1026) - \[unstable] Support Unmarshaler interface for tables and array tables by [@​pelletier](https://github.com/pelletier) in [#​1027](pelletier/go-toml#1027) ##### Fixed bugs - Add missing UnmarshalTOML call by [@​pelletier](https://github.com/pelletier) in [#​996](pelletier/go-toml#996) - Handle array table into an empty slice by [@​pelletier](https://github.com/pelletier) in [#​997](pelletier/go-toml#997) - Unwrap strict errors by [@​bersace](https://github.com/bersace) in [#​1012](pelletier/go-toml#1012) - Fix leap second handling found by fuzz by [@​pelletier](https://github.com/pelletier) in [#​1019](pelletier/go-toml#1019) - Fix nil pointer map values not being marshaled by [@​pelletier](https://github.com/pelletier) in [#​1025](pelletier/go-toml#1025) - Fix panic when unmarshaling datetime values to incompatible types ([#​1028](pelletier/go-toml#1028)) by [@​pelletier](https://github.com/pelletier) in [#​1029](pelletier/go-toml#1029) - Fix parser error pointing to wrong line at EOF without trailing newline by [@​pelletier](https://github.com/pelletier) in [#​1041](pelletier/go-toml#1041) ##### Documentation - Improve Unmarshaling README by [@​heckelson](https://github.com/heckelson) in [#​1016](pelletier/go-toml#1016) - Create AGENTS.md guidelines file by [@​pelletier](https://github.com/pelletier) in [#​1017](pelletier/go-toml#1017) ##### Other changes - Unsafe package removal by [@​pelletier](https://github.com/pelletier) in [#​1021](pelletier/go-toml#1021) - Bump CI and test scripts to Go 1.26 by [@​pelletier](https://github.com/pelletier) in [#​1030](pelletier/go-toml#1030) #### New Contributors - [@​virtuald](https://github.com/virtuald) made their first contribution in [#​991](pelletier/go-toml#991) - [@​NathanBaulch](https://github.com/NathanBaulch) made their first contribution in [#​999](pelletier/go-toml#999) - [@​bersace](https://github.com/bersace) made their first contribution in [#​1012](pelletier/go-toml#1012) - [@​flyn-org](https://github.com/flyn-org) made their first contribution in [#​1013](pelletier/go-toml#1013) - [@​heckelson](https://github.com/heckelson) made their first contribution in [#​1016](pelletier/go-toml#1016) **Full Changelog**: <pelletier/go-toml@v2.2.4...v2.3.0> </details> --- ### Configuration 📅 **Schedule**: Branch creation - At 12:00 AM through 04:59 AM and 10:00 PM through 11:59 PM, Monday through Friday ( * 0-4,22-23 * * 1-5 ), Only on Sunday and Saturday ( * * * * 0,6 ) (UTC), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.

Fixes #990
Strictly speaking, this would break backwards compatibility if anyone was using a textual comparison of the output of Marshal (as opposed to the semantic content). Could hide it behind an additional tag/option if that seems like a concern.
I've not used benchstat before, but I think there's a slight performance penalty, but worth it for me :)
