Oxygene Changelog

[0.1.0] - 2026-08-17

• added custom, much faster Base32 encoder/decoder, dropping base32 gem dependency
• added CARRepo (subclass of CARArchive) for parsing and processing ATProto repo CAR archives:
  • use #walk_all_nodes { |path, section_cid| ... } to iterate over all records in the repo
  • use #commit or #commit_section to access repo commit data
• reorganized CID class:
  • it now stores only the initial JSON/binary form and avoids generating the other until requested
  • #json_form returns JSON string starting with 'b' (to_s is an alias)
  • #cbor_form returns the binary string starting with \x00
  • #raw_data returns the binary string without the CBOR \x00 prefix
  • #data is an alias for #raw_data for backwards compatibility
  • both the input and output strings for JSON/binary form are frozen so they can't be modified from outside
  • added more data validations
• optimized section parsing & lookup in CARArchive:
  • it keeps an internal Hash of sections as { raw CID data => section }, but doesn't build it by default unless explicitly enabled
  • use section_with_cid(cid, use_map: true) to populate and use the lookup hashmap
  • either a CID object or its #cbor_form can be used for lookup
  • use section_with_cid(cid, return_body: false) to return a CARSection instead of its decoded body object directly; this will be the default behavior in a future version
  • various internal optimizations in the decoding code
  • added more data validations
  • added #parsed_sections helper
• changed the API of CARSection:
  • use #json_body to return the body with values recursively converted to use $bytes and $link where needed, as before
  • use #decoded_body to return the body only decoded from CBOR, but without the recursive conversion
  • #body is an alias for #json_body for now for backwards compatibility
• added unit tests & YARD docs
