I saw a site using 4.00.997201785 and was wondering whats new in 4.00.997201785 over whats in ver 3.x??
There have been many additions to Texis since the release of version 3.01. You may have seen a site using the beta release of Webinator version 4, and some of the new features in Texis support that, such as the addition of more <urlcp> settings for fetching, and the addition of <sysutils>, and the <rmcommon> functions, and the ability for Texis to schedule script execution.
There have also been many performance enhancements and additions of features and knobs that may not be of interest to most users, but can be very useful when they are needed, for example with LIKEP the ability to specify how many terms must match, rather than relying on Texis' default, and the ability to generate results in XML so they can be used as an ADO result set.
