- segment cache error fixed as the cause of crashes when clicking again on the same node after other construction activities
- internally switched to geoutil 1.7
- minor code optimizations

- Info panel output accelerated
- internally switched to geoutil 1.6
- minor code optimizations

- old resp. duplicate and therefore unnecessary ParamBuilder script removed

- reliable event synchronization using a click counter to prevent marker deletion and crashes due to quick multiple clicks
- immediate intermediate step display by the info panel without prior mouse movement
- text change in collision check tooltip
- information field does not appear before the tool is activated
- internal code optimizations

- fixed an incorrect delete command in the automatic marker correction that was previously only randomly neutralized by the marker tool
- switched internally to ParamBuilder v1.2
- internal code optimizations
- recommendation in the guide to construction work in pause mode

- error messages adjusted
- cycle counter implemented against lagging in the engine thread caused by info panel being called too often
- fixed incomplete update of the info panel; cycle counter optimized and mouse standstill event generated
- data preparation for info field swapped out as a function in extended_calcutil
- bottom bar event only when changing to 'invisible'
- alertbox message for protected switches adjusted to the width of the box

- correct 'state' assignment when exiting/saving, prevents an 'abandoned' info panel from appearing after loading a map
- stopped entering unnecessary data in sav.lua
- code optimization
- geoutil 1.5, minor changes
- entered URL in mod.lua
- checkboxes instead of yes/no buttons, tooltips added

- Disabling 'Auto-delete marker' will keep the marker and allow step-by-step height testing.
- 'Protect switches and crossovers' prevents editing of switches and crossovers to avoid creating unintentional bends.
- Optimized communication with Marker
- wkm_geoutil_v1_2.lua is also used here, complemented by wknt_extended_calcutil.lua.
