Add a TODO on the latest HISTORY.md entry

Also disable version updater on Iris benchmark source code files. It may runs ever faster than before if you started the benchmarks immediately after the banner  👍

+
+This evening, on the next version 8.3.5:
+
+Able to pre-calculate, register and map different (relative) paths inside a single controller
+with zero performance cost.
+
+Meaning that in the future you will be able to use something like these:
+
+If `app.Controller("/user", new(user.Controller))`
+
+- `func(c *Controller) Get()` - `GET:/user` , as usual.
+- `func(c *Controller) Post()` - `POST:/user`, as usual.
+- `func(c *Controller) GetLogin()` - `GET:/user/login`
+- `func(c *Controller) PostLogin()` - `POST:/user/login`
+- `func(c *Controller) GetProfileFollowers()` - `GET:/user/profile/followers`
