What changed in each Forever beta build
One page per beta build: what Blizzard announced, what shows up in the client, and where the trackers disagree. Talent changes are computed from our own snapshots, not copied from anyone.
We read the trees eight times: off the BlizzCon preview, out of build 1.60.1.70009, out of 1.60.1.70170, out of 1.60.1.70291, out of 1.60.1.70425, out of 1.60.1.70630, out of 1.60.1.70753 and out of 1.60.1.70755. Twenty-two builds we did not read - 69893, 69913 and 69977 before the first, 70094, 70058 and 70124 between the first two, 70178, 70205, 70235 and 70245 between the next two, 70334, 70338 and 70374 between the two after that, 70450 and 70532 before 70630, 70634, 70658, 70685 and 70707 between 70630 and 70753, and the live clients 70790, 70840 and 70862 after the last - and no snapshot of them exists here. Everything this page says about them is other people's reporting, marked as such. That is also why the talent diff on the 70009 page covers everything that happened since BlizzCon rather than that build alone. The 70170, 70291, 70425 and 70630 diffs are cleaner than that sounds: for the clients in between, the reporting is the strongest kind available without a snapshot - a machine that regenerates from the CDN and found nothing to commit, or a file diff without a single data table - so what each diff shows is that build's own. The 70753 diff is not: the four clients before it changed data tables, so it covers everything since 70630. Three more exceptions: the 70630 snapshot also carries the server hotfixes of 28 and 30 October for six classes, which are not in the client's files, and the 70753 snapshot follows Blizzard's notes of 2 November for 67 talents where the game data does not show their numbers yet, and the 70755 snapshot carries the server hotfixes of 3 and 4 November, which rearranged three trees without a note from Blizzard.
One page per beta build. What sits under "read from the client" comes from our own talent snapshots in data/talent-snapshots - the same files the calculator is built from. What sits under "reported" comes from other people's builds and is labelled as such, including where those reports disagree with each other.
