What the most recent Taiwan maintenance opened, what it scheduled next, and which guide to read for each item. When the next maintenance is recorded, this page moves to it by itself; older ones slide down, and the full history lives on Game Patches.
Item lines are quoted from the official Taiwan notice (Traditional Chinese); the summaries and “what to do first” notes are ours.
The 9/30 maintenance (06:00–10:00) opened the MapleStory collaboration — five server-wide events, the Pink Bean fashion and pet lucky boxes (opened only with their own collab tickets) and collab bundles, all until 10/21 05:59 — and applied the Mas Abyss reward-pool change announced on 9/16: three new unique items, and a make-up box for anyone who cleared between 9/28 06:00 and 9/30 05:59. It scheduled Glas Ghaibhleann Very Hard and Abyss Hell 5 for 10/5, added 6 unique items and 26 prototype runes, let pursuit trigger more than once, and paid the Abyss Fashion Support Pack compensation. The Pink Bean outfit becomes dyeable at the 10/7 maintenance. Claim the compensation by 10/1 23:59.
All five events count per server and one character reaching the goal is enough: pick one server and collect the four named rewards there — 10 days of attendance, 600 seconds of instrument play, 96 daily challenges, 7 Slime Dash clears (that is also the prize-draw entry). Collab tickets expire 10/21 05:59; the Pink Bean outfit only becomes dyeable at the 10/7 maintenance, so decide on the box after you see the dye regions.

Content the notice dated but did not open during the maintenance. Countdowns run on Taiwan time and switch to “Opened” once the moment passes; where the notice says “planned”, that wording is kept.
The 9/16 maintenance (extended to 09:00) scheduled the White Succubus raid for 9/21 (4 players or solo, one weekly loot drop per character, first reset 9/28), Abyss Hell 4 for 9/28, and a change to Mas Abyss unique-gear rewards after the 9/30 update. It also started the autumn event run, fixed several bugs and pulled three shop bundles. Compensation had to be claimed by 9/17.

A short unscheduled maintenance (06:00–07:50) the day after the big update: it fixed missing Sweet Breeze challenge-bundle rewards, re-sent the full-set bundle bonus that closed early, and fixed a quest NPC's dialogue. Compensation had to be claimed by 9/11.
