Public Release → Grand Launch
MapleStory Classic World client changelog: Public Release to the Grand Launch
Read from the client: the Grand Launch of 21 October 2026 against the Public Release of 6 October 2026, 242 additions, 227 removals and 291 revisions. New: 17 monsters with Stumpy and Faust among them, 31 maps, the Excavation Site among them, 38 items, 27 quests and 18 recipes. Removed: 227 Cash Shop catalog lines, none of them on sale.
Upstream’s datamine did not publish a diff for this build, so this site compares its two exports itself, in the shape the datamine’s own diffs take. The Public Release’s changes are one build back: Closed Online Test 2 to the Public Release.
About this page
What it is
Two client exports compared field by field, not Nexon’s patch notes, so it shows changes nobody announced. It can’t say why something changed: a typo fix and a rebalance look the same.
What it misses
Drop rates, shop stock and quiz answers live on the server, so they never show up here. Stumpy and the Excavation Site arrived in this build, so they are in it; anything the server switched on without a client change is not. What the Public Release left out of the second test is in the diff before this one, and its pages are kept here, marked CoT2.
Written by this site from two exports of the OSMS Data Explorer datamine, the Public Release as frozen on 6 October 2026 and the Grand Launch as pulled on 21 October 2026. More on the sources.
