-## Important note 
-If you want to re-run a read2tree analysis (after facing an error, or changing the inputs), please make sure that you removed the `mplog.log` file and the output folder. Alternatively you could start from an empty folder. Otherwise, read2tree might use the faulty output of previous unfinished run.

-We are working on a new [read2tree version](https://github.com/DessimozLab/read2tree/tree/minimap2) using the [minimap2](https://github.com/lh3/minimap2) aligner, which is much faster. For this version, the `--read_type` argument could be either `short`, `long-hifi` or `long-ont`. You could also use `--threads 40` to be used with minimap2. 
+## New release 
+We are now realasing Read2Tree v2.0.0 with improved spead and logging. As the aligner, we are now using minimap2 [minimap2](https://github.com/lh3/minimap2). Also, MAFFT and IQtree are now using multiple threads. We would suggest to run r2t with `--debug` which helps to debug later. Please note that arguments have slightly changed in this release(see below for details).
