BASEmesh 2.3.0

Dear Users of BASEMENT

We are pleased to announce the release of BASEmesh version 2.3.0. You can install and upgrade to the new version directly using pip or ifyou use QGIS plugin, simply upgrade in plugin manager.

Key Changes:
- The new version performs large meshing and cleaning up drastically faster than before (~1 sec run time now for a previously ~1 hour task).
- Elevation looking up from a mesh is also much faster now (~12x faster)
- Fixed nodestring ordering for bent or zigzagging line strings, which could previously result in incorrectly ordered nodestrings.
- Breaking change for Python users: the deprecated basemesh.basechange import path is gone. Use import basechange instead.

For QGIS Plugin users:
- The progress bars now work normally and show what's happening;
- Fixed a bug where some valid elevation mesh layers didn't show up in the Advanced Interpolation tab;
- Linux builds of the plugin now include the same compiled speed-up as Windows.

Other changes:
- BASEchange: fixed the last cross-section of a CSV/tabulated channel not picking up the template's default values, unlike every other cross-section in the channel.

Kind regards
The development team of BASEMENT
