These changes come in on Monday 21st January.
The amended note (36 pages) can be found here. Even more helpfully, a Notice to Practitioners (kind of an EM for practice notes) has been made available here.
Most changes are minor procedural tweaks. Perhaps the most significant change is the Criminal Registry's express prohibition on filings by post or facsimile, except where the accused is self-represented. Tiresome arguments about when documents were sent or received are going. I expect this will soon become the norm across jurisdictions.
