 ## Compatibility, performance, and ease-of-installation
 
-Myokit's `Simulation` class currently requires users to have a specific compiler installed, as well as a version of Sundials compiled with that compiler.
-In addition, the on-the-fly compilation via `distutils`/`setuptools` has gotten slightly slower on linux in recent versions, but significantly slower on some Windows installations.
+Myokit's `Simulation` class currently requires users to have a Python-specific C compiler installed, along with compatibly compiled Sundials binaries.
+In addition, in recent Python versions on-the-fly compilation via `distutils`/`setuptools` has gotten slightly slower on linux, but significantly slower on some Windows installs.
 A rewrite of the simulation class to use a precompiled simulation engine and model code generated through llvmlite could solve both problems.
 
-- Tickets related to this "Simulation revamp" are grouped in a [project](https://github.com/myokit/myokit/projects/5), but currently represent only a fraction of the expected work.
-- Including precompiled parts will require a change in the way Myokit is distributed; a proof-of-concept can be found [here](https://github.com/myokit/beta/).

 - A [full API documentation](https://myokit.readthedocs.io/) which includes a short user guide.

 Two major improvements are planned:
 
-- Improved calculation of "sensitivities" of simulation results w.r.t. parameters, see this [project](https://github.com/myokit/myokit/projects/6).
- - Issues related to initial conditions with parameter dependecies are group in a separate [project](https://github.com/myokit/myokit/projects/13).

   - Allow these models to be created independent of the `myokit.Model` class (for model selection studies) based on [pilot work by Joey](https://github.com/CardiacModelling/markov-builder).

 ## Maintenance
 
 - Implement singularity fixes created for [cellmlmanip with Maurice](https://github.com/myokit/myokit/issues/809).
 - Units should have the option to "remember" a preferred representation [#783](https://github.com/myokit/myokit/issues/783).
 - Creation of symbolic expressions should be simplified through operator overloading [#798](https://github.com/myokit/myokit/issues/798).
