<div dir="ltr">The first question is which conda channel are you using? The correct channel is "conda-forge" and this channel definitely has 2.3.0 as the latest version for Windows 10 - see <br><br><a href="https://anaconda.org/conda-forge/pdal">https://anaconda.org/conda-forge/pdal</a><br><br>If you are not sure or are using another channel - remove pdal from your conda environment and re-install with `conda -c conda-forge install pdal`.<br><br>If the channel is correct - then most likely you have something installed in your environment that requires a version of one of the dependencies at a lower version than is supported by version 2.3. The PDAL version 2.3 dependencies are :<br><br><span style="font-family:"Museo Sans Rounded",Lato,"Helvetica
