 * MTM2 has 8 outputs by default.
 * Same name for MTM2 outputs and GENGT2 inputs.
 * D18599 block has been added.
+* Gnuplot window does not get closed automatically with a mouse click, which lets the user interact with the graph. (Press q or click on X to close).
+* It is now easier to work with Y2 axis in PLOT block (e.g. range is set and displayed automatically)
+* Sun position was sometimes in the wrong quadrant, in the tropics, close to the horizon.
+* PLOTP writes X/Y/Parameter and not just X/Y, so that Parameter can be used (e.g. for line colors)
 
 ### GUI
-
 * "Show INSEL model" has a nicer output (no trailing zeroes).
 * Default language is English.
 * Default model size is 8x8.
-* INSEL GUI now uses Java 15.
+* INSEL GUI now uses Java 15+.
 * New GUI themes (light/dark modes, high-contrast for accessibility, ...)
 * New keyboard shortcuts:
-  * <kbd>Ctrl</kbd><kbd>R</kbd> to run a model
-  * <kbd>Ctrl</kbd><kbd>P</kbd> to pause a model
-  * <kbd>Ctrl</kbd><kbd>Z</kbd> to stop a model

 * An experimental LIVECHART Block is available in the GUI. Data is displayed in real time.
-* The color of links can be changed globally and single links can be hidden and made visible again.
+* New icons (from FontAwesome).
+* CLOCK block now shows progress.
+* Models are not marked as changed when they are simply  opened or run.
+* The content of Vseit files isn't shuffled anymore anytime they are saved.
+* Blocks are placed on a regular grid when imported from an insel file.
+* Old INSEL 7 files (.ins, .vee) cannot be imported anymore. To import them, please use INSEL 8.2.
+* The installed version can be copied to any folder (e.g. on a USB drive). Two portable bat scripts are included on windows.
 
 ### INSEL Engine
-
 * INSEL Core can use Fortran 90.
 * Easier way to integrate and share userblocks (UB library files can have any name, e.g. `libInselAlice.dll`, `libInselBob.dll`).
 * `libInselCommunity` has been created, and it contains useful user blocks from the community (e.g. `UBSTORAGE`, CHP blocks, ...).

 * Can list every available block with `insel -b`.
 * Can list the version of every module with `insel -v`.
 * Possible to use underscores in constants : `C stuttgart_latitude 48.77`
+* Simulink blocks and logics have been removed, since they have not been used for years.
 
 ## Beta-testers: What to test?
 
 * Please backup every model before opening them in INSEL 8.3! (e.g. the whole `Documents/insel.work` folder)
 * Please backup userblock libraries if you have any.
-* Please backup your palette folder. (`%AppData%\INSEL`)
 * Please keep an INSEL 8.2 installer, just in case.
 * Remove INSEL 8.2.
+* Install INSEL 8.3. (+Gnuplot + GUI, MSYS2 is only needed for developing user blocks)
 * Start INSEL 8.3 GUI.
 * A new folder should be created at startup.
 * Old models should still be readable.
 * Old PLOT blocks should be converted.
 * Old coordinates should be converted. If they are defined via constants, please update constants manually.
-* Can userblocks still be used? They probably need to get compiled again.
+* Can user blocks still be used? They probably need to get compiled again.
 * Models shouldn't run slower than before.
 * Please report any crash (with any `replay_*.log` and `hs_err_*.log` file you can find) (TODO: Where?).
 * A gitlab project has been created in order to collect user-feedback: https://transfer.hft-stuttgart.de/gitlab/insel/insel-8-3/-/issues

-* Text might not be readable in dark modes.
-* Name and parameters for userblocks might not be displayed correctly.
 * Underscores in filenames or function names might break documentation.

 ## What's next?
 
 * Fix more bugs.
 * New GUI, based on Eclipse Sirius (with zoom / undo / web-interface / ...).
 * Double-precision instead of single-precision floats.
+* Allow blocks to be written in Python.
 * PVGIS Block (month as input, coordinates as parameters, monthly average irradiances and temperatures as output).
 * SORT Block (n inputs, data is saved during simulation, sorted at the end according to the first input, and written to a file).
 * READCSV Block.
