+### Sparsey 0.7
+
+![Sparsey](sparsey.png)
+
+[Sparsey] by [@LechintanTudor] is a sparse set-based Entity Component System
+with beautiful and concise syntax.
+
+The biggest change in this release was the removal of component change detection
+which had a significant impact on performance and memory usage. As a result,
+Sparsey performs much better in all benchmarks and the codebase is easier to
+maintain.
+
+The systems module received a major overhaul with an improved scheduling
+algorithm, allowing more systems to run in parallel, and an important usability
+improvement allowing systems to be added to schedules without having to call
+`.system()` on the system functions.
