CHANGE LOG

CHANGES FOR VERSION 6.11.0 (as compared to 6.10.0)

• AFL: added formatDateTimeISO for ISO formatting regardless of locale settings, example:
  Filter = 1;
AddColumn( DateTime(), "DT ISO", formatDateTimeISO ); // generate a date/time column that is always in ISO format regardless of regional settings in Windows
  
• AFL: MxFromString was slow on very large matrices (>100000 cells) due to poor performance of strtod function from Microsoft C runtime. Now MxFromString does not use it and is even 1000 times faster on 100K+ cell matrices (5ms vs 5second)
• ASCII importer can now be even 20 times faster when importing NEW (non existing) data that were oddly sorted (like for example in reverse order - descending dates instead of ascending).
• ASCII importer is now twice as fast when updating already existing quotes thanks to using in-house code instead of msvcrt functions.
• Charting: Fibonacci maximum user-definable level increased to 9000% (from 1000%)
• Idle processing is forced now every 125 ms (instead of 250ms) in Analysis window to update UI components more frequently under heavy CPU load
• Ruin stop is identified by Short(ruin) / Sell(ruin) instead of Short(6) / Sell(6)
• Startup splash screen is displayed a little sooner now and some pre-loading of editor components is done at start to save time to open editor later
• When there were thousands of files in "Formulas" folder opening editor for the first time could take some time. Now this time is significantly reduced.
