Original release notes

Version 2.0 is the biggest decoder upgrade since DitDah Decoder launched.

• All-new decoding engine: timing, spacing, and character patterns are now decided together probabilistically instead of by fixed thresholds — dramatically better accuracy on real-world signals, weak stations, and fading (QSB)
• Auto Gain and Adaptive Threshold have been overhauled to work together automatically — the default settings now work best, with no manual tuning needed
• Redesigned signal meter that shows the true signal level, noise floor, and the decoder's actual detection point
• New Text Revisions mode: decoded text appears sooner, and the decoder may briefly refine the last few characters as more audio arrives — like predictive text (can be turned off)
• Many bug fixes and stability improvements
