 # Pharos Changelog
 
+## 0.5.0 - 2020-02-17
+
+- **BREAKING CHANGE**: `Observable::observe` is now an async function. This was needed to make it possible to send
+  events to a pharos object from different async tasks. So far notifying was async, but observing was not. However
+  in order to be able to use a mutex, we need both operations to be one or the other. On wasm, one cannot block the
+  thread hence the choice for an async mutex, but in order to lock that we have to be in async context.
+  A new helper type `SharedPharos` has been introduced to conveniently use pharos from a shared reference.
+- **BREAKING CHANGE**: rename `pharos::Error` to `PharErr`. I want to move away from types that are just called `Error`.
+  This allows conveniently exporting the error type at crate level.
+- no longer depend on futures-channel appart from the main futures lib. It's annoying if a dependant crate
+  want's to patch futures in Cargo.toml.
+- move to github actions after travis becomes a paid service.
+
 ## 0.4.2 - 2019-11-13

+# Contributing
+
+This repository accepts contributions. Ideas, questions, feature requests and bug reports can be filed through Github issues.
+
+Pull Requests are welcome on Github. By committing pull requests, you accept that your code might be modified and reformatted to fit the project coding style or to improve the implementation. Contributed code is considered licensed under the same license as the rest of the project unless explicitly agreed otherwise. See the `LICENCE` file.
+
+Please discuss what you want to see modified before filing a pull request if you don't want to be doing work that might be rejected.
+
+
+## Code formatting
+
+I understand my code formatting style is quite uncommon, but it is deliberate and helps readability for me. Unfortunately, it cannot be achieved with automated tools like `rustfmt`. **Feel free to contribute code formatted however you are comfortable writing it**. I am happy to reformat during the review process. If you are uncomfortable reading my code, I suggest running `rustfmt` on the entire source tree or set your line-height to 1.2 instead of the common 1.5, which will make it look a lot less over the top.
+
+
+# git workflow
+
+Please file PR's against the `dev` branch, don't forget to update the documentation.
