* Changes in forms: using new tables supporting copy/paste of multiple cells

* Support Unicode, including object names

* Trackway exhaust system in platform

* Optional tunnel height for calculating critical velocity

* Number of trains in path report

* Activity level of passengers

* Time constant in Given flow model

* Calculate power consumption in Filter model. Fan efficiency

* Warning when total front area of meeting trains > tunnel cross section area.

* Revised palette; added new control models ??

* Included source code for Block library

* "Selection box" in palette allows dragging multiple icon to schematic view

* Script function for moving fire along path report

* Supported new extension "Parametric runs"

* If a longterm simulation crashed, open automatically the failed system

* Show the license day left in "About" dialog

* Implementation of new standard for computing critical velocity.

* Automatically download climate files from EQUA site

Changes in models and functions

=================

* Leak Changed calculation of mean air density

* Filter Added fan efficiency parameters

* Route Fixed exponential stochastic delay

Added CO2 emission from passengers

* Selector New model for simultaneous switch of multiple signals

* Section Fix bug in velocity computation at sensors.

Enhanced pressure sensors

Extra parameter for calculating critical velocity

* RailSection

Counting number of trains per segment

Added run-time checking of available cross-section area

* Platform

Counting number of trains

Fixed bugs

==========

* Fixed pressure computation at sensors.

* Fixed energy meters for multi-year simulations

* Fixed bugs in editing paths for routes and path reports

* Fixed calculation of train movement in case the train cannot

keep the speed on sloping segment

* Fixes calculation of train movement in case when the power is not enough to achiewe

the given speed at the ends of segment

* Fixed error in checking of height in nodes

* Fixed initialization of emission tables for new vehicle types

* Allows connecting custom energy meters

* Fixes export of variables in path report to Excel

* Fixes script command :clean

* Fixes calculation of lenght of sloping segments for road traffic in reverse direction

* Removed irrelevant warning "Variable error in end file" in longterm simulation

* Fixed bug in export diagrams to Excel

* Fixed initialization data for changed tunnel segments before longterm simulation

* Fixed label in emission form for equipment (NOx instead of wrong NO2)
