Changelog

Sourced from ron's changelog.

[0.12.1] - 2026-03-30

Format Changes

• Ignore #![type = "..."] and #![schema = "..."] attributes (#596)

Bug Fixes

• Fixed parsing of integer type suffixes for non-decimal numbers (#600)

[0.12.0] - 2025-11-12

API Changes

• Breaking: Removed the ron::error::Error::Base64Error variant. (#566)
• Added into_inner() method to ron::ser::Serializer to retrieve the inner writer. (#588)
• Removed the base64 dependency. (#566)

Format Changes

• Format-Breaking: Remote base64-encoded byte strings deserialisation, replaced by Rusty byte strings in v0.9.0 (#566)

Bug Fixes

• Fixed untagged enum deserialisation for serde >= 1.0.220 with better serde content detection (#582)

[0.11.0] - 2025-08-27

API Changes

• Breaking: SpannedError now stores the full error span in span: Span { start: Position, end: Position }`, to facilitate, e.g., language server highlighting of syntax errors.
• Breaking: Added no_std support via a new std feature (enabled by default). With default features disabled, you must enable the std feature to access de::from_reader, and the std::io operations on Options, such as from_reader, from_reader_seed, to_io_writer, and to_io_writer_pretty (#567)
• Breaking: Fixed (again) ron::value::Number to ensure it is non-exhaustive, to avoid breaking matches when feature unification enables more of its variants than expected (#568)

Examples

• Add a new example file_read_write_vec.rs for reading and writing Vec<T> to/from files. (#573)

[0.10.1] - 2025-04-08

API Changes

• Add ron::Options::to_io_writer and ron::Options::to_io_writer_pretty to allow writing into an io::Writer (#561)
• Breaking: ron::value::Number is now non-exhaustive, to avoid breaking matches when feature unification enables more of its variants than expected (#564)

[0.9.0] - 2025-03-18

API Changes

• Add ron::value::RawValue helper type which can (de)serialize any valid RON (#407)
