Candid 0.10.20

• Non-breaking changes:
  • fix: subtyping and coercion rules for optional types
  • fix: coercion of values into nested optional types
  • fix: values of types reserved at any context do not coerce into values of type null
  • fix: missing record fields of type null in the textual format are decoded into a default value

candid_parser 0.2.3 & didc 0.5.3

• Non-breaking changes:
  • Rust binding: Sets service_name based on top level name config
  • Rust binding: Makes struct field and function names are more intuitive and predictable.
    • Rust binding convert identifiers into cases conforms to Rust naming convention. Since didc v0.5, some identifiers started to be renamed. E.g. struct field amount_e8s was renamed to amount_e_8_s. Now, field name like amount_e8s won't be renamed.
    • Please check to_identifier_case() in https://github.com/dfinity/candid/blob/master/rust/candid_parser/src/bindings/rust/identifier.rs for more details.
    • Note: different identifiers might be converted to the same one, potentially causing naming conflicts. If this happens, you'll need to use the Type Selector Config to specify custom names.

Full Changelog: dfinity/stable-structures@v0.7.0...v0.7.2

v0.7.0

Highlights

• Faster BTreeMap: Fewer clones via into_bytes (breaking API), lazy iterator (breaking API), faster traversal, batch read/write
• Breaking API: Public methods now panic instead of returning Result
• Benchmarks: Improved coverage (NNS, I/O chunks, principals)
• Improved CI & Docs: Better logs, custom branches benchmark support, and updated documentation.

Migration Guide

To upgrade to v0.7.0, fix any build errors by applying the following changes:

• Implement into_bytes for your types to support the updated API
• Update iteration logic: instead of (key, value) tuples, iterate over entry objects and use entry.key() and entry.value() to lazily access data
• Remove .unwrap() where methods no longer return Result — these now panic on misuse

What's Changed

• Breaking API change
  • perf!: remove excessive cloning in btreemap.insert (breaking API change) by @​maksymar in dfinity/stable-structures#322
  • refactor!: replace Result with panic in stable-structures (breaking API change) API by @​maksymar in dfinity/stable-structures#351
