• Edwin talked about the freshly-pushed code that pipelines trace-recording and assembling, giving background about why we did it and how it works — he’s going to write up more info about how to interpret the new verbose mode. There was some discussion as to how the pipeline might be parallelized.

• Edwin & Steven mentioned that Michael Daumling’s rewrite of TT String is looking good and will probably be ready by end of week.

• Edwin mentioned that we are hopefully about a week away from trace trees being ready to push.
