v0.20.7

Fixed

• Replaced the remaining fallible Status::try_from conversions in the Tonic
  adapter tests with the infallible Status::from API so Clippy's
  unnecessary_fallible_conversions lint passes under -D warnings.

v0.20.6

Fixed

• Restored compilation on Rust 1.90+ by aliasing the infallible gRPC
  conversion error to core::convert::Infallible and re-exporting it without
  exposing the private convert::tonic module.

v0.20.5

Changed

• Rewrote the English and Russian READMEs to reflect the matured workspace, feature flags, telemetry flows and transport integrations introduced across the 0.20 releases.

Fixed

• Promoted the gRPC converter to an infallible From<Error> implementation
  while retaining the TryFrom API via the new documented
  StatusConversionError, satisfying Clippy's infallible conversion lint.
• Collapsed nested metadata guards in the Tonic adapter and reused borrowed
  booleans to silence Clippy without regressing runtime behaviour.
• Simplified the AppResult alias test to avoid large Err variant warnings
  from Clippy's result_large_err lint.

v0.20.4

Added

• Implemented FromStr support for AppCode together with a lightweight
  ParseAppCodeError so RFC7807 responses and documentation examples can parse
  machine codes without bespoke helpers.

Fixed

• Removed the redundant #![cfg(feature = "axum")] attribute and tightened
  Axum, SQLx and Tonic integration tests to satisfy -D warnings builds.
• Allowed attaching JSON details via ErrorResponse::with_details without
  tripping Clippy's result_large_err lint by documenting the intentional
  AppError return shape.

v0.20.3

Fixed

• Restored the Axum transport adapter in builds by wiring the convert::axum
  module into the crate graph and relaxing the tests to validate responses via
  serde_json::Value instead of requiring ProblemJson deserialization.
• Hardened converter telemetry for Redis, Reqwest, SQLx, Tonic and multipart
  integrations by owning metadata strings where necessary and covering
  non-exhaustive enums so the crate compiles cleanly on Rust 1.90.
• Reworked ProblemJson metadata internals to use Cow<'static, str> keys and
  values, preserving zero-copy behaviour for borrowed data while allowing owned
  fallbacks required by the updated converters.

v0.20.2

Fixed

• Restored compatibility with Rust 1.89 by updating gRPC, Redis, SQLx and
  serde_json integrations to avoid deprecated APIs, unsafe environment
  mutations and Debug requirements that no longer hold.
• Added deterministic backtrace preference overrides for unit tests so
  telemetry behavior remains covered without mutating global environment
  variables.
• Ensured config error mapping gracefully handles new non-exhaustive variants
  by falling back to a generic context that captures the formatted error.

v0.20.1

Changed

• Enriched converter metadata across multipart, redis, reqwest,
  serde_json and sqlx integrations to surface HTTP status details,
  retry-after hints and structured failure positions while keeping existing
  error categories intact.
• Updated the Teloxide mapping to classify ApiError::InvalidToken as
  Unauthorized and hash potentially sensitive network error details before
  emitting telemetry.

Tests

• Extended integration tests to assert the new metadata fields, retry hints,
  and redaction policies covering the updated converters.

v0.20.0

Added

• Added a Context::redact_field_mut builder method to tweak metadata
  redaction policies in place before attaching additional fields.
• Extended response tests to cover JSON serialization of redacted payloads and
  hashed metadata along with checks for the opt-in internal formatters.

Changed

• Verified ErrorResponse and ProblemJson serialization respects message and
  metadata redaction policies, ensuring secrets stay out of wire payloads while
  keeping diagnostic logging intact.

v0.19.0

Changed

• Reworked AppError storage to keep sources behind shared Arc handles and
  lazily capture optional Backtrace snapshots without allocating when
  RUST_BACKTRACE disables them.
• Updated the masterror::Error derive and ResultExt conversions to forward
  sources/backtraces automatically under the new storage layout.

Tests

• Added regression coverage for chained error sources and conditional
  backtrace capture driven by the RUST_BACKTRACE environment variable.

v0.18.0

Added

• Added the AppCode::UserAlreadyExists classification and mapped it to RFC7807
  responses with the appropriate retry hint.

Changed

• Switched all integration converters in src/convert/* to build structured
  Context metadata before producing Error values, including HTTP status,
  operation, endpoint, duration and retry/edit flags.
• Extended integration tests to validate the enriched metadata, retry behavior
  and error code/category mappings across the updated converters.
