| ## [0.4.17] - 2022-04-29 |
| |
| * Update `kv_unstable` internal dependencies. |
| |
| ## [0.4.16] - 2022-03-22 |
| |
| * Fix a conflict with unqualified `Option` use in macros. |
| |
| ## [0.4.15] - 2022-02-23 |
| |
| * Silence a warning about the deprecated `spin_loop_hint`. |
| * Relax ordering in the atomic `set_max_level` call. |
| * Add thumbv4t-none-eabi to targets that don't support atomics |
| * Allow levels to be iterated over. |
| * Implement `Log` on some common wrapper types. |
| * Improvements to test coverage. |
| * Improvements to documentation. |
| * Add key-value support to the `log!` macros. |
| * Tighten `kv_unstable` internal dependencies so they don't bump past their current alpha. |
| * Add a simple visit API to `kv_unstable`. |
| * Support `NonZero*` integers as values in structured logging |
| * Support static strings as keys in structured logging |
| |
| ## [0.4.14] - 2021-01-27 |
| |
| * Remove the `__private_api_log_lit` special case. |
| * Fixed incorrect combination of `kv_unstable` and `std` features causing compile failures. |
| * Remove unstable `Value::to_*` conversions that were incorrectly using `as`. |
| * Rename unstable `Value::to_error` to `Value::to_borrowed_error`. |
| |
| ## [0.4.13] - 2021-01-11 |
| |
| * This is the same as `0.4.11`, except with a `kv_unstable_std` feature added to aid migrating current dependents to `0.4.14` (which was originally going to be `0.4.13` until it was decided to create a patch from `0.4.11` to minimize disruption). |
| |
| ## [0.4.12] - 2020-12-24 |
| |
| ### New |
| |
| * Support platforms without atomics by racing instead of failing to compile |
| * Implement `Log` for `Box<T: Log>` |
| * Update `cfg-if` to `1.0` |
| * Internal reworks of the structured logging API. Removed the `Fill` API |
| and added `source::as_map` and `source::as_list` to easily serialize a `Source` |
| as either a map of `{key: value, ..}` or as a list of `[(key, value), ..]`. |
| |
| ### Fixed |
| |
| * Fixed deserialization of `LevelFilter` to use their `u64` index variants |
| |
| ## [0.4.11] - 2020-07-09 |
| |
| ### New |
| |
| * Support coercing structured values into concrete types. |
| * Reference the `win_dbg_logger` in the readme. |
| |
| ### Fixed |
| |
| * Updates a few deprecated items used internally. |
| * Fixed issues in docs and expands sections. |
| * Show the correct build badge in the readme. |
| * Fix up a possible inference breakage with structured value errors. |
| * Respect formatting flags in structured value formatting. |
| |
| ## [0.4.10] - 2019-12-16 (yanked) |
| |
| ### Fixed |
| |
| * Fixed the `log!` macros so they work in expression context (this regressed in `0.4.9`, which has been yanked). |
| |
| ## [0.4.9] - 2019-12-12 (yanked) |
| |
| ### Minimum Supported Rust Version |
| |
| This release bumps the minimum compiler version to `1.31.0`. This was mainly needed for `cfg-if`, |
| but between `1.16.0` and `1.31.0` there are a lot of language and library improvements we now |
| take advantage of. |
| |
| ### New |
| |
| * Unstable support for capturing key-value pairs in a record using the `log!` macros |
| |
| ### Improved |
| |
| * Better documentation for max level filters. |
| * Internal updates to line up with bumped MSRV |
| |
| ## [0.4.8] - 2019-07-28 |
| |
| ### New |
| |
| * Support attempting to get `Record` fields as static strings. |
| |
| ## [0.4.7] - 2019-07-06 |
| |
| ### New |
| |
| * Support for embedded environments with thread-unsafe initialization. |
| * Initial unstable support for capturing structured data under the `kv_unstable` |
| feature gate. This new API doesn't affect existing users and may change in future |
| patches (so those changes may not appear in the changelog until it stabilizes). |
| |
| ### Improved |
| |
| * Docs for using `log` with the 2018 edition. |
| * Error messages for macros missing arguments. |
| |
| ## [0.4.6] - 2018-10-27 |
| |
| ### Improved |
| |
| * Support 2018-style macro import for the `log_enabled!` macro. |
| |
| ## [0.4.5] - 2018-09-03 |
| |
| ### Improved |
| |
| * Make `log`'s internal helper macros less likely to conflict with user-defined |
| macros. |
| |
| ## [0.4.4] - 2018-08-17 |
| |
| ### Improved |
| |
| * Support 2018-style imports of the log macros. |
| |
| ## [0.4.3] - 2018-06-29 |
| |
| ### Improved |
| |
| * More code generation improvements. |
| |
| ## [0.4.2] - 2018-06-05 |
| |
| ### Improved |
| |
| * Log invocations now generate less code. |
| |
| ### Fixed |
| |
| * Example Logger implementations now properly set the max log level. |
| |
| ## [0.4.1] - 2017-12-30 |
| |
| ### Fixed |
| |
| * Some doc links were fixed. |
| |
| ## [0.4.0] - 2017-12-24 |
| |
| The changes in this release include cleanup of some obscure functionality and a more robust public |
| API designed to support bridges to other logging systems, and provide more flexibility to new |
| features in the future. |
| |
| ### Compatibility |
| |
| Vast portions of the Rust ecosystem use the 0.3.x release series of log, and we don't want to force |
| the community to go through the pain of upgrading every crate to 0.4.x at the exact same time. Along |
| with 0.4.0, we've published a new 0.3.9 release which acts as a "shim" over 0.4.0. This will allow |
| crates using either version to coexist without losing messages from one side or the other. |
| |
| There is one caveat - a log message generated by a crate using 0.4.x but consumed by a logging |
| implementation using 0.3.x will not have a file name or module path. Applications affected by this |
| can upgrade their logging implementations to one using 0.4.x to avoid losing this information. The |
| other direction does not lose any information, fortunately! |
| |
| **TL;DR** Libraries should feel comfortable upgrading to 0.4.0 without treating that as a breaking |
| change. Applications may need to update their logging implementation (e.g. env-logger) to a newer |
| version using log 0.4.x to avoid losing module and file information. |
| |
| ### New |
| |
| * The crate is now `no_std` by default. |
| * `Level` and `LevelFilter` now implement `Serialize` and `Deserialize` when the `serde` feature is |
| enabled. |
| * The `Record` and `Metadata` types can now be constructed by third-party code via a builder API. |
| * The `logger` free function returns a reference to the logger implementation. This, along with the |
| ability to construct `Record`s, makes it possible to bridge from another logging framework to |
| this one without digging into the private internals of the crate. The standard `error!` `warn!`, |
| etc, macros now exclusively use the public API of the crate rather than "secret" internal APIs. |
| * `Log::flush` has been added to allow crates to tell the logging implementation to ensure that all |
| "in flight" log events have been persisted. This can be used, for example, just before an |
| application exits to ensure that asynchronous log sinks finish their work. |
| |
| ### Removed |
| |
| * The `shutdown` and `shutdown_raw` functions have been removed. Supporting shutdown significantly |
| complicated the implementation and imposed a performance cost on each logging operation. |
| * The `log_panics` function and its associated `nightly` Cargo feature have been removed. Use the |
| [log-panics](https://crates.io/crates/log-panics) instead. |
| |
| ### Changed |
| |
| * The `Log` prefix has been removed from type names. For example, `LogLevelFilter` is now |
| `LevelFilter`, and `LogRecord` is now `Record`. |
| * The `MaxLogLevelFilter` object has been removed in favor of a `set_max_level` free function. |
| * The `set_logger` free functions have been restructured. The logger is now directly passed to the |
| functions rather than a closure which returns the logger. `set_logger` now takes a `&'static |
| Log` and is usable in `no_std` contexts in place of the old `set_logger_raw`. `set_boxed_logger` |
| is a convenience function which takes a `Box<Log>` but otherwise acts like `set_logger`. It |
| requires the `std` feature. |
| * The `file` and `module_path` values in `Record` no longer have the `'static` lifetime to support |
| integration with other logging frameworks that don't provide a `'static` lifetime for the |
| equivalent values. |
| * The `file`, `line`, and `module_path` values in `Record` are now `Option`s to support integration |
| with other logging frameworks that don't provide those values. |
| |
| ### In the Future |
| |
| * We're looking to add support for *structured* logging - the inclusion of extra key-value pairs of |
| information in a log event in addition to the normal string message. This should be able to be |
| added in a backwards compatible manner to the 0.4.x series when the design is worked out. |
