+## 0.3.0
+
+### Fixed
+
+  * Ruby 3.1.x compatibility [#13](https://github.com/nodanaonlyzuul/asciiart/issues/13)  
+
+### (semi) Tested Ruby Versions
+
+I hope to have a better automated test matrix in the future but...
+
+  * ruby 3.1.0p0   (2021-12-25 revision fb4df44d16) [x86_64-darwin20]
+  * ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x86_64-darwin20]

+
+## 0.2.0
+
+### Notes
+
+#### Rehabilitation & being a better citizen
+
+This gem started as a fast-and-loose side project in 2014.
+It mostly worked for many years, with no need for major updates.
+In January 2022, I noticed a lot of the gem & its dependencies' syntax didn't play well in modern versions of Ruby.
+
+#### Tagging & Github Releases
+
+This is the version where I started caring about using tags & GH releases.
+
+### Fixed
+
+  * Fixing ability to open a URL via cli.[[#12](https://github.com/nodanaonlyzuul/asciiart/pull/12)]
+  * Fixing color output issues.[[#12](https://github.com/nodanaonlyzuul/asciiart/pull/12)]
+
+## < 0.2.0
+
+These were the dark ages.
+I'm sorry.
