Where do I find the patch notes?

I am currently running a game of Dungeon of the Mad Mage on Roll20. When starting Roll20 today, I got a message that the Dungeon of the Mad Mage module I bought from the marketplace had been updated to version 1.9, and that I could press a button to update it. While updating, I shortly saw a link to patch notes, however the update finished so fast, I didn't have time to click on the link. So then I tried to find the 1.9 patch notes for Dungeon of the Mad Mage on the marketplace or elsewhere on Roll20, but couldn't find them anywhere. Any hint where the patch notes are hiding?

I don't know if a detailed list is available to the end user. The last one, 1.9, was: Behir stat block updated. But I only was able to discover that because I hadn't patched my copy yet. The last one that was front-facing and detailed, I pulled through a link in the Change Log . From February of 2019: Patch 1.3 Bestiary Flying Trident attack name updated to “Trident” and now accurately reflects damage type Ice Devil added to module Intellect Devourer token now accurately reflects AC Mind Flayer Arcanist now has spells added to character sheet Stalagma Steelshadow’s breath weapon now accurately reflects damage type Volo “Volothamp” Geddarm now links correctly to his art handout Maps Area token moved to GM layer in area 13a of level 3 Dynamic lighting updated for illusory wall in area 4e of level 5 Bigby’s Hand token added to GM layer in area 15b of level 6 Gray Slaadi added to GM layer in area 36c of level 6 (room number moved to accommodate additions) Spirit Nagas added to GM layer in area 15c of level 8 Drow added to map in area 26 of level 10 Syrrak Argonrae’s token named in area 25c of level 10 X added to map in area 12c of level 13 Covered pit marker added to map, gelatinous cube moved to appropriate place and GM layer in area 2 of level 15 Living unseen servant moved to GM layer in area 12 of level 15 Ice devil added to GM layer in area 13a of level 15 Stone golem moved to GM layer in area 23 of level 15 Dotted circle added on GM layer in area 5 of level 23 Square added on GM layer in area 6a of level 23 Aryx now correctly named in room 9B of level 23 Skullport Upper grid size updated to 5 ft. per square and all tokens on map to correspond to updated size Fixed Kuo Toa AC in area 10b of Skullport Text/Links Arcane Lock  spell link updated in area 37 of level 7 Redundant text removed for area 13 of level 11 Death tyrant links updated in level 15 Figurine of Wondrous Power  linked in area 35 of level 15 But they are almost never that detailed.
