My Position on the last few weeks of Twtxt spec discussions:

• We increase the Hash length from 7 to 11.
  
• We formalise the Update Commands extension.
  
• We amend the Twt Hash and Metadata extension to state:
  

Feed authors that wish to change the location of their feed (once Twts have been published) must append a new # url = comment to their feed to indicate the new location and thus change the “Hashing URI” used for Twts from that point onward.

This has implications of the “order” of a feed, and we should either do one of two things, either:

• Mandate that feeds are append-only.
  
• Or amend the Metadata spec with a new field that denotes the order of the feed so clients can make sense of “inline” comments in the feed. – This would also imply that the default order is (of course) append-only. Suggestion: # direction = [append|prepend]
