# Change Log All notable changes to this project will be documented in this file. The format is based on [Keep a Changelog](http://keepachangelog.com/) and this project adheres to [Semantic Versioning](http://semver.org/). ## 2.7.0 - 2020-11-29 * Add #% for alternate display of the value part * Implement `Eq` for dynamic `Key`s * Add `emit_error` to `Serializer`, `#` for serializing foreign errors, and `impl Value for std::io::Error` ## 2.6.0 - 2019-10-28 * Add #? for pretty-debug printing the value part ## 2.5.3 - ????-??-?? * Use fully qualified call syntax for `Logger::log` in macros ## 2.5.2 - 2019-07-22 * Restored parsing of `Level` and `FilterLevel` truncated names ## 2.5.1 - 2019-07-11 * Added parsing of `Level` and `FilterLevel` short names ## 2.5.0 - 2019-07-11 * Added `FilterLevel::accepts` * Added `as_str`, `as_short_str` and `Display` to `FilterLevel` ## 2.4.1 - 2018-10-03 * disable support for i128/u128 types if rustc is old ## 2.4.0 - 2018-09-19 * Implement Value for 128 bit integers * Add support 2018-style macro imports * **WARNING**: This is a breaking change that we couldn't avoid. Users using explicitly macro import (like `#[macro_use(slog_o)]`) must add `__slog_builtin` to the import list. * Bump miminum supported Rust version to 1.26 ## 2.3.3 - 2018-07-20 * `impl Value for SocketAddr` ## 2.3.2 - 2018-07-20 * Revert broken changes: * Make `?` and `%` formatters in `kv!` more flexible * Export local inner macros to help with Rust 2018 testing ## 2.3.0 - 2018-07-20 * Export local inner macros to help with Rust 2018 testing * Stabilize `Record::new` * Make `?` and `%` formatters in `kv!` more flexible ## 2.2.3 - 2018-03-28 * Fix (again) problems introduced by `2.2.1` ## 2.2.2 - 2018-03-26 * Fix problems introduced by `2.2.1` ## 2.2.1 - 2018-03-24 * Add `is_x_enabled()` for queering (imprecise) log-level ## 2.2.0 - 2018-02-13 ### Added * Support for named format arguments in format messages. They will now become respectively named key-value pairs. ## 2.1.0 - 2017-12-10 ### Added * Support for nested-values through `emit_serde`, behind `nested-values` feature flag, disabled by default for backward compatibility. **Note**: Consider unstable for the time being. * Support for dynamic key (`String` vs `&'static str`), behind `dynamic-keys` feature flag, disabled by default for backward compatibility. **Note**: Consider unstable for the time being. ## 2.0.12 - 2017-09-14 ### Changed * `#[allow(dead_code)` on unused log statements ## 2.0.11 - 2017-09-13 ### Changed * Impl `Value` for `std::path::Display` ## 2.0.10 - 2017-09-09 ### Changed * Remove unnecessary 'static bound on `FnValue` ## 2.0.9 - 2017-08-23 ### Changed * Update README ## 2.0.6 - 2017-05-27 ### Changed * Fix for https://github.com/rust-lang/rust/pull/42125 ## 2.0.5 - 2017-05-15 ### Changed * Relicense under MPL/Apache/MIT ## 2.0.4 - 2017-05-05 ### Fixed * Documentation improvements ## 2.0.3 - 2017-05-05 ### Fixed * Documentation fixes ## 2.0.2 - 2017-04-12 ### Fixed * Compile time logging level filtering ## 2.0.0 - 2017-04-11 ### Changed (since v1; bigger picture) * Unified and simplified logging macros structure and ordering. * Added logging Record `tags`. * Refactored key-value pairs traits and structures and overall handling. * It's now possible to `impl KV for MyStruct`. * `kv!` can be used to create on stack key-value list. * `KV`-implementing data can appear on the key-value list directly. * Support chaining of `OwnedKVList`s. Existing `Logger` can be used as a `Drain` to allow custom handling logic for a part of the logging hierarchy. * Added associated `Ok` type to `Drain`. * Support for `Drain`s unwind safety. * Refactored `Record` to optimize performance on async operations. * `slog-extra` has been renamed to `slog-async` since that's the only functionality it contained. * `slog-stream` is obsoleted and won't be used in `slog v2` at all. It was a wrong abstraction. `Decorators` functionality was moved to `slog-term`. * `slog-term` provides open `Decorator` traits to allow multiple terminal / file writing backends. * `slog-term` default `Decorator`s use `term` crate and should work correctly on all supported OSes. * `DrainExt` has been removed and utility methods moved directly to `Drain` * `slog-stdlog` utilizes `slog-scope` directly. * Support for "typed" `Logger`s to allow squeezing last drops of performance possible, at the cost of `T` in `Logger`. ## 2.0.0-3.1 - 2017-03-25 ### Added * Support for `fmt::Display` values with `%` in `kv!` ## 2.0.0-3.0 - 2017-03-25 ### Changed * Added support for own `KV` and `Value` implementations * Streamlined the formatting syntax for `log!` and friends; **BREAKING** * Lazy values need explicit `FnValue` wrapper; **BREKING** ### Added * `kv!` macro ## 2.0.0-2.2 - 2017-03-19 ### Fixes * Bunch of trait-related fixes ## 2.0.0-2.1 - 2017-03-11 ### Fixed * Require `MapErr` and `Filter` to be `UnwindSafe` ## 2.0.0-2.0 - 2017-03-11 ### Changed * Make `Logger::root` return "erased" version * Introduce `Logger::root_typed` for "non-erased" `Logger` creation ## 2.0.0-1.0 - 2017-02-23 ### Fixed * `fmt::Debug` for `MutexDrainError` ### Changed * Parametrize `Logger` over the `Drain` it holds and introduce "erased" version * Enforcing `UnwindSafe` `Drain`s for `Logger`s * Refactored key-value pairs traits and structures * Renamed some types * Support chaining of `OwnedKVList`s * Added associated `Ok` type to `Drain` * Refactored `Record` to optimize performance on async operations * Minimal rustc version required: `1.15.0` * `DrainExt` has been removed and utility methods moved directly to `Drain` ### Added * Macros to create `OwnedKV` and `BorrowedKV` * `Logger` implements `Drain` ## 1.5.0 - 2017-01-19 ### Changed * Order of key-value pairs is now strictly defined ### Added * `Logger` implements `Drain` ### Deprecated * Creation of `OwnedKeyValueList` ## 1.4.1 - 2017-01-19 ### Fixed * Fix an invalid syntax exposed by nightly rust change (Issue #103) ## 1.4.0 - 2016-12-27 ### Changed * Updated documentation ### Deprecated * `OwnedKeyValueList::id` ## 1.3.2 - 2016-11-19 ### Added * `slog_o` as an alternative name for `o` ## 1.3.1 - 2016-11-19 ### Fixed * Cargo publishing mistake. ## 1.3.0 - 2016-10-31 ### Changed * **BREAKING**: Removed default `Send+Sync` from `Drain` ## 1.2.1 - 2016-10-27 ### Added * `OwnedKeyValueList::id` for owned key value unique identification ## 1.2.0 - 2016-10-21 ### Changed * **BREAKING**: `Serializer` takes `key : &'static str` now ### Fixed * Corner cases in `info!(...)` and other macros ## 1.1.0 - 2016-10-17 ### Changed * **BREAKING**: Rewrite handling of owned values. ## 1.0.1 ### Fixed * `use std` in `o!` ### Added * Implement `fmt::Debug` for `Logger` ## 1.0.0 - 2016-09-21 First stable release.
