Fern Versions Save

• Re-add compatibility for rust versions 1.16.0+, and add CI testing with rustc 1.16.0 to ensure this is kept in the future.
• Add some more general documentation updates and clarity increases.
• Add a CHANGELOG.md which mirrors git tag releases.
• Update documentation links to point to docs.rs rather than custom hosted documentation.
• Fix ColoredLevelConfig::default being an inherent method rather than an implementation of the Default trait.
• Add direct support for the syslog crate under the "syslog-3" feature flag.
  • Add a module worth of documentation for using fern with syslog.

• Re-add support for colored log levels with the 'colored' feature
  • This was initially implemented in fern 0.4.4 by @nihilus, but support was accidentally dropped in fern 0.5.0.
• Fix the ability to run tests on windows, and refactor integration tests for developer clarity
• Update documentation for clarity

Short list of changes in 0.5.0:

• Updated from log 0.3 to log 0.4. Both are interoperable, but using log 0.4 provides a much cleaner log interface for fern to use internally
• Removed fern::FernLog.
• Renamed fern::color::ColoredLogLevelConfig to ColoredLevelConfig
• Greatly simplified testing

• Update from log 0.3 to log 0.4. Both log versions are interoperable, but line numbers from libraries using 0.4 won't show up in binaries with recievers using log 0.4.
  • To clarify: both fern 0.4 and 0.5 will work perfectly with all libraries, but line numbers will always be 0 if you use fern 0.4 and log 0.4.
• Remove fern::FernLog. With log 0.4, log records can be constructed directly, and fern loggers can now recieve just a record rather than a record and the formatted display string.
• Notable changes in the log crate: log::LogLevel is renamed to log::Level, and log::LogLevelFilter is renamed to log::LevelFilter.
• fern::color::ColoredLogLevelConfig has been renamed to fern::color::ColoredLevelConfig to match log crate renamings.
• fern tests have been greatly simplified with the new support for creating log records manually. it's now possible to just run "cargo test" and test all of fern's functionality.

• Add support for sending to an std::sync::mpsc::Sender as a log output

• Documentation hotfix after a too-early release of version 0.4.1

• Lots of documentation tweaks and reworking
• Add CONTRIBUTING file and update README to invite new contributors
• Improve example application to be more realistic
• A few small internal improvements, mostly code cleanup here

• Rework API surface to be builder-based for simpler configuration

  • Rename DispatchConfig to Dispatch, OutputConfig to Output and FernLogger to FernLog

• Rework inner log structure for more efficiency

  • Different outputs are now stored in an enum rather than every sublogger being a Box<FernLog> with dynamic dispatch
  • Remove LogError; handle errors within individual loggers now - and only within loggers which actually need it
  • Remove unnecessary wrapping of streams with an Arc (now just uses Mutex for File streams)
  • Remove unnecessary wrapping of Stdout and Stderr streams with a Mutex, when they are already synchronized
  • Pass around just &fmt::Arguments + &log::LogRecord instead of passing each individual LogRecord part

• Move opening of files and stdout/stderr from configuration "building" to configuring

  • Instead of taking OpenOptions, log configuration now just takes an already-opened std::io::File object
  • fern::InitError is now a convenience API, and is never returned from any fern APIs

• Redo formatting to work without allocation - formatting closures now finish with a callback rather than returning a value

• Update examples to use chrono instead of the time crate

  • This removes another extra allocation - chrono can format time directly to a writer, without allocating intermediate the result to a String

• Add much more documentation: almost every builder method has a full example, and all features should be thoroughly explained

• Add appveyor and travis-ci badges to README and Cargo.toml

• Build changes to .travis.yml
• Add html_root_url doc attribute
• Add file_with_line_sep and file_with_options_and_line_sep configuration construction options to allow specifying a line separator other than the default '\n'

• Update for rustc version e9080ec39 (1.0.0-beta.2)
• Update to use no_test to ignore doc tests, rather than ignore
• Remove all stability attributes on public types
• Add rust version matrix for testing on travis, to test on beta as well as nightly builds

• Update for rustc version 9854143cb (1.0.0-beta)
• Derive Clone for all types deriving Copy
• Update docs a bit for that switch to time crate
• Switch to time crate instead of chrono for tests, as chrono hasn't updated for rustc 1.0.0-beta yet.
• Instead of implementing a pseudo-time crate as a workaround for https://github.com/rust-lang/cargo/issues/1474, just disable the doc test, and copy the code to a separate file in tests/
