And the first cut with the new one:
You can see that the old one is much rougher, where the saw has torn its way through the wood. The rings are raised, because the dull blade has torn out more of the soft earlywood the harder latewood. The edges are splintered and there are burn marks. On the other hand, the new one is smooth, because the blade was sharp enough for a clean cut. No burning, minimal splintering. It was also a much quicker and easier cut.
Mostly this is to say, sawblades are not that expensive or difficult to change, and I should have replaced this one sooner!
