According to the my announcement from the last week, the development versions are going to appear much faster than before. This is the first of such events. The third dev of OPT 2.0.0 is ready to download. This time, I've paid much attention to the attribute processing. They can do a lot of interesting things with the tags they've been added to. The earl implementation has been ready so far - there were even examples showing the "opt:section" working. But to satisfy both me and probably other programmers, I had to extend it.

Unsually, the final HTML code of the website is composed of several smaller templates containing smaller pieces of it. There are many techniques of combining them. In PHP template engines, the most popular are two forms: manual execution of the templates from the script side and the include directive. Similar solution can be found in OPT 1.x, however in the new version, it should be forgotten - unless we use the quirks mode, the parser does not let us to call the parse() method more than once. In the beginning, I planned to replace it by extending inclusion with "sequences" - a groups of templates to include with their own variables and cache settings. However, one day I was asked on my blog by Coldpeer, whether OPT will support template inheritance. I googled for a while, I looked at it and thought it might be cool. That's how the implementation began.
