Thanks for the quick replies! I have not checked the SRD, but it seems a significant amount of the errata, even the older ones form the PHB, aren't reflected from what I see. Here are some key examples, I am happy to do a full audit if it helps, I have time and I live and breathe the compendium for my games ^_^ DMG Only case I found was new errata <a href="https://roll20.net/compendium/dnd5e/Rod%20of%20Lordly%20Might#content" rel="nofollow">https://roll20.net/compendium/dnd5e/Rod%20of%20Lordly%20Might#content</a> - The following text is
appended to the sentence on button 1: “(you choose the type of
sword).” PHB A lot of this isn't reflected in the compendium including older changes: I don't see any class descriptions updated for the latest round, an easy litmus is Spell Slots changing from "your spells" to "your [class] spells". It looks like the revisions to Ranger weren't part of the SRD to begin with though as the mentioned sections aren't in the compendium that I see <a href="https://roll20.net/compendium/dnd5e/The%20Environment#h-Darkvision" rel="nofollow">https://roll20.net/compendium/dnd5e/The%20Environment#h-Darkvision</a> - older change - The second sentence of this subsection now reads, “Within
a specified range, a creature with darkvision can see in dim light as if it were
bright light and in darkness as if it were
dim light, so areas of darkness are only
lightly obscured as far as that creature is
concerned.” <a href="https://roll20.net/compendium/dnd5e/Combat#toc_44" rel="nofollow">https://roll20.net/compendium/dnd5e/Combat#toc_44</a> - Shoving and other parts of this section aren't reflecting errata <a href="https://roll20.net/compendium/dnd5e/Acid%20Splash#content" rel="nofollow">https://roll20.net/compendium/dnd5e/Acid%20Splash#content</a> - I don't see any of the spells reflecting errata, such as Acid Splash and Call Lightning. <a href="https://roll20.net/compendium/dnd5e/Moonbeam#content" rel="nofollow">https://roll20.net/compendium/dnd5e/Moonbeam#content</a> - Older errata like for Moonbeam is also not reflected - The words “up
to” now appear in “move the beam up
to 60 feet in any direction.” <a href="https://roll20.net/compendium/dnd5e/Brown%20Bear#content" rel="nofollow">https://roll20.net/compendium/dnd5e/Brown%20Bear#content</a> - Both PHB and MM errata correct brown bear to +6 attack, and black bear to +4 MM I don't see newer errata reflected but the older errata is in place so far as I see, examples: <a href="https://roll20.net/compendium/dnd5e/Efreeti#content" rel="nofollow">https://roll20.net/compendium/dnd5e/Efreeti#content</a> - Innate Spellcasting: “3/day” changed to
“3/day each.” <a href="https://roll20.net/compendium/dnd5e/Harpy#content" rel="nofollow">https://roll20.net/compendium/dnd5e/Harpy#content</a> - reflects the older errata but has a typo, "the [target] must move on its turn toward the harpy by the most direct route" <a href="https://roll20.net/compendium/dnd5e/Purple%20Worm#content" rel="nofollow">https://roll20.net/compendium/dnd5e/Purple%20Worm#content</a> - +14 to hit instead of +9
