+## [4.0.0] / 16 January 2020
+
+Majority of using projects don't have to worry by this being a new major version.
+
+**TLDR;** if your project manipulates `Writer.prototype.parse | Writer.cache` directly or uses `.to_html()`, you probably have to change that code.
+
+This release allows the internal template cache to be customised, either by disabling it completely
+or provide a custom strategy deciding how the cache should behave when mustache.js parses templates.
+
+```js
+const mustache = require('mustache');
+
+// disable caching
+Mustache.templateCache = undefined;
+
+// or use a built-in Map in modern environments
+Mustache.templateCache = new Map();
+```
+
+Projects that wanted to customise the caching behaviour in earlier versions of mustache.js were forced to
+override internal method responsible for parsing templates; `Writer.prototype.parse`. In short, that was unfortunate
+because there is more than caching happening in that method.
+
+We've improved that now by introducing a first class API that only affects template caching.
+
+The default template cache behaves as before and is still compatible with older JavaScript environments.
+For those who wants to provide a custom more sopisiticated caching strategy, one can do that with an object that adheres to the following requirements:
+
+```ts
+{
+  set(cacheKey: string, value: string): void
+  get(cacheKey: string): string | undefined
+  clear(): void
+}
+```
