Current version: 1.1.4 (released January 2017)

(released January 2017)

On Windows, the library is bulit without /Zc:wchar_t- so wchar_t is now a compile defined type, which is the VS default behavior. The /Zc:wchar_t- option is not required to link with wide string methods in FileIO and Version.
SDK class no longer override the new and delete operators. This alows users of the SDK to override new.
Added support for new LAS 1.4 channels ScannerChannel, ClassFlags, and NearInfrared.
Added ProgressDelegate::displayWarning(), which is an optional override, it is called with informitive messages.
Added PointInfo::init() methods for building PointInfo object that have a subset of channels of a given PointInfo or PointData object.

Added a new GPS time channel. Replaced the CHANNEL_NAME_GPSTime macro with CHANNEL_NAME_GPSTime_Week and added CHANNEL_NAME_GPSTime_Adjusted. GPSTIme_Week is the number of seconds since midnight Sunday. GPSTime_Adjusted is the satellite GPS Time minus 1×10⁹.
