+<b>argmin</b> is a Rust library which offers a range of numerical optimization methods and a framework for 
+developing optimization algorithms.  For details about the design of argmin and its features I suggest having a look at
+[the website](https://argmin-rs.org),
+[the book](https://argmin-rs.org/book),
+[Github](https://github.com/argmin-rs/argmin),
+[crates.io](https://crates.io/crates/argmin) and
+[lib.rs](https://lib.rs/crates/argmin).
+
+This is a short summary of the changes in argmin 0.9.0 (and 0.8.1 as this version didn't get its own blog post) compared to 0.8.0.
+Feel free to reach out via [Github](https://github.com/argmin-rs/argmin) or the new [Discord server](https://discord.gg/fYB8AwxxMW) if you encounter any issues during the upgrade.
+
+## argmin 0.9.0
+
+* Line search now correctly searches over gradient instead of parameter vector ([@DevonMorris](https://github.com/DevonMorris)) (**Breaking change**)
+* SteepestDescent now correctly keeps track of prev_param ([@DevonMorris](https://github.com/DevonMorris))
+* `ArgminInv` is now also implemented for 1D matrices ([@sdrap](https://github.com/sdrap))
+* [@cjordan](https://github.com/cjordan) added another [example](https://github.com/argmin-rs/argmin/blob/main/argmin/examples/neldermead-cubic.rs) of how to use Nelder-Mead
+* Fixed a couple of typos and mistakes in the documentation ([@itrumper](https://github.com/itrumper), [@imeckler](https://github.com/imeckler), [@stefan-k](https://github.com/stefan-k))
+
+## argmin 0.8.1
+
+* The `Serialize` and `Deserialize` derives for `ObserverMode` somehow got lost. This was fixed by [@maoe](https://github.com/maoe)
+
+## Other news
+
+The [`cobyla`](https://crates.io/crates/cobyla) crate was made compatible with argmin (Thanks to [@relf](https://github.com/relf)).
+
+## New Discord server
+
+Since the old Gitter channel didn't get much use we now finally have a [Discord server](https://discord.gg/fYB8AwxxMW)! I'm looking forward to seeing many of you there!
