Came here to see the likely outrage over formats and praise over the other changes - have not been surprised. It's a bit unfair of me to concentrate on the negative, but here goes anyway...
That one can't see exact numbers is ridiculous. Storage limits can be exceeded easily now. Rounding adds to this. The use of more than one letter presumably restricts field length to 2 decimal places rather than the previous display on the overviews at the top of the screen; if not, why give less info than before?
The previously introduced ludicrous leading triple zeros that came up on times have now been suppressed - can coders now remove the equally irritating leading single zero, please? It used to be much easier to see which times were coming to fruition if only one digit was displayed, contrasting with the larger amounts on other entries. Working on small screens and with old eyes it makes a difference to me. (Not as much as removing the Captchas would, especially with cheats available to bypass them, but I guess I'm tilting at windmills here.)
Finally, regarding time displays, I thought a change that should be made would be to include number of days against info on trades arriving, shown at the bottom of a town's trading port. These show the time of day, but with the introduction especially of freighters, the info becomes temporarily misleading if they need more than 24 hours to arrive. Yes, such full info is available in the military advisor, but it needs to be scrolled through to find the specific destination.
Just to show I'm not a 100% moaner, I expect your main 2 changes to be highly useful (not tried them yet) and it shows commitment to a fine game that the "end of the worlders" have been predicting would meet its demise soon for a decade now. Well done.
