FWIW, here's my notes on comparison of Glimmerdrift 990 v 1105
Worlds = 349 vs 350
Basic UWP (A123456-A) = 63 are the same, 287 Changed
Starports = 59 Changes. 38 Upgrades, 21 Downgrades
Size = 83 Changes, 71 are +1 or +2 in size
Atmosphere = 25 Changes, 19 are -1 to -6
Hydrographic = 16 Changes, 15 increases, 13 occurred where the Atmosphere also changed
Population = 117 Changes, 37 Increased, 80 decreased. 49 minus 1, 21 plus 1
Government = 58 Changes
Law Level = 56 Changes, 16 where the Government also changed
Tech Level = 154 Changes, 104 Increases, mostly to 5,6,7. 50 decreases appears to A, B, C
I didn't bother with Stellar, as I read that a lot of revisions were done to that. Also didn't bother with bases or PBG. Although there was one glaring population change, Slate (2322) grew from 7 million to 7 billion. And Canton aka Makag in 993 (3040) grew from 10 Billion to 90 Billion.
The rest of the population increases, even when they were greater than 1 Billion, were usually inline with possible population growth over 100 years. Growth from 10 billion to 20 billion is within the realm of possibilities.
There were 6 worlds that decreased by 10 Billion (-10% to 50%) and 4 that decreased by 1 Billion (-20% to 50%). Not recommended for holiday tours.
