What should happen if you stay at the version  v0.20.1  and not go to the v0.21.
I"m have started again about 3 weeks ago with the version v0.20.1 after troubles with my computer . Now i am still 4 years and 16 weeks behind. Block 235195 That goes very slow. I get the mension that it will still take 6 weeks to have completend the download.
I am affraid if i go to another version , i have to start completely again.
