+## 5.x
+
+This release comes with breaking changes to what was previously known as "Compute scripts". The endpoints for compute scripts
+were historically only publicly visible in the official API specs for a short amount of time after which they became undocumented (exact timeline unknown).
+
+With the [announcement](https://bunny.net/blog/introducing-bunny-edge-scripting-a-better-way-to-build-and-deploy-applications-at-the-edge/) of "Edge Scripting" on November 7th (2024),
+it became apparent (in hindsight) that the new edge scripts are basically compute scripts (with some minor adaptations).
+
+As edge scripts are now part of what is referred as the "Edge Scripting API" (even though it still uses the same domain of `api.bunny.net`),
+this release reflects (signature) changes in the BunnyNet-PHP library that refactors the previously known compute scripts from the `BaseAPI` to edge scripts in the `EdgeScriptingAPI`.
+
+The `4.x` branch will now no longer be maintained.
+
+### ‼️ Breaking changes
+
+The signature changes are displayed in the table below.
+
+| **4.x**                                        | **5.x**                                                                                                                                | **5.x signature notes**   |
