+### Project status
+
+I wrote the initial version of this library in 2015, and haven't written Rust professionally since then.
+I consider this as close as I'll ever get to a "finished" project and don't plan on adding any more features to it.
+
+It is still maintained and I try and merge pull requests for fixes, improvements, and features; though I generally turn down pull requests for large or complex features that go outside the library's aim to be a simple logger.
+If you need more, the `log` module has a list of [available logging implementations](https://docs.rs/log/latest/log/#available-logging-implementations), or you could consider forking `simple_logger` and building on top of it.
+
+### Breaking changes
 
 - **Version 2.0.0 changes the default from displaying timestamps in the local timezone to displaying timestamps in UTC.** See issue [#52](https://github.com/borntyping/rust-simple_logger/issues/52) for more information.
