DIHtmlLabel 1.0 – 6. January 2003

Initial public release as DIHtmlLabel. Major changes compared to the original JvLinkLabel are as follows:
- Unicode Support, the main new feature of TDIHtmlLabel, has become possible by applying DIHtmlParser as the underlying HTML parsing engine. Therefore TDIHtmlLabel is able to display characters from many different languages right next to each other, even on Win95 and Win98. It does so by converting all common HTML entities, both named and numeric, to UnicodeStrings internally: α = α – β = β – γ = γ A = A – &#66; = B – C = C
- TDIHtmlLabel reads all HTML data assigned to the Caption property as Latin1. Additional character sets can easily be added if demand arises.
- Attribute Values for the <A href=MyValue> and <DYNAMIC id=MyValue> tags, which are passed to the OnLinkClick and the DoDynamicTagInit events.
Many internal optimizations which speed up performance and decrease memory requirements.
