CHANGELOG.md 

v0.6.1

* DEFECT #19: The `value` field of v1 binary annotations must always be encoded as a JSON string or boolean, and no other type. (HT @chad-g-adams & @adriancole).



v0.6.0

* Trace and span ids are now treated as hex strings (binaries) throughout:

  * avoids multiple places where previous representation was converted from integer to hex string, e.g. in logging, propagation and reporting.

* Trace context encoding and decoding vastly optimised over previous benchmark (60% faster decoding, 40% faster encoding).



v0.5.0

* Use [`Jason`](https://github.com/michalmuskala/jason) as default JSON encoder, remove `Poison`. 

  * Can be overriden by setting `:tapper` Application var `:json_codec` to the name of the preferred module.



v0.4.1

* Fix deprecation warnings from System.convert_time_unit/3 (thanks to @indrekj)

* Lock max `poison` version to 4.0.0 since its API was changed in 4.0.1 removing `Poison.encode_to_iodata/2` (https://github.com/devinus/poison/commit/a4208a6252f4e58fbcc8d9fd2f4f64c99e974cc8#r26410188)



v0.4.0

* **Requires Elixir 1.6+**

* `Tapper.Reporter.AsyncReporter` (thanks to @indrekj)

* Tapper will now start reporters under its supervision tree if given as `{module, args}` supervisor-style tuple.

* Enforces that reporters are a module implementing `Tapper.Api.Reporter`, or a function with arity-1.



v0.3.6

* Allow 1.x versions of HTTPoison.



v0.3.5

* DEFECT: shared span flag should only be true for joined traces, not all `:server` traces.



v0.3.4

* Add `Tapper.Reporter.Null` (HT @TKasekamp)

* Doc fixes.

* Update deps.



v0.3.3

* DEFECT: "unknown" being recorded as service name.

* DEFECT: remove `trace_id` from Logger context (HT @TKasekamp)

* suppress all server logging unless `server_trace` is set to a log level (HT @TKasekamp)



v0.3.2

* `Tapper.error_message/1` (and `TapperCtx.error_message`) should take any term (and convert to a string) for convenience.

* update `dialyxir`.



v0.3.1

* DEFECT: joined traces (shared spans) should not set duration on root span.

* use custom `Logger.metadata/1` implementation for small perf gain.

* parse child span name from opts in server rather than client, for tiny perf gain.

* tiny refactoring things.



v0.3.0



* Use [`DeferredConfig`](https://hexdocs.pm/deferred_config/readme.html) for univeral application of `{:system, ENV_VAR}` style indirections in config.

* Add `Tapper.Ctx` contextual API.

* Change `Logger.metadata` key from `tapper_id` to `trace_id` and ensure it is just the hexidecimal encoding of the trace id. Document it.

* Optimisations; see [benchmarking](benchmarking/BENCHMARKS.md).



v0.2.0



Initial public release.



v0.1.1



Initial release.
