Micronaut 2.0 Milestone 1

If you are using Micronaut, please try 2.0.0.M1 and give us feedback. We are really excited about this release but we need to find the upgrade pain points to have a great 2.0.0.GA.

Micronaut Servlet

Micronaut Servlet provides support for replacing the Netty-based HTTP server that comes with Micronaut with either Jetty, Tomcat, or Undertow, which may be of interest to those who are already familiar with the thread-per-request model of traditional servlet containers and have an existing large investment in the servlet ecosystem.
Additionally, the Jetty and Tomcat implementations can be used with GraalVM native image to produce native servlet applications that start in milliseconds and consume very little memory.


Telegram Bot to exchange currencies

I wrote a Telegram Bot with Micronaut (more about this in a future issue). You can use it obtain foreign exchange rates published by the European Central Bank.

I keep my accounting books in EUR but I get paid most of my income in USD so exchanging currencies is a daily task for me.
