Most “exciting” releases break your code. #Java26 doesn’t. It compiles, runs, and improves performance—thanks to G1 GC and HTTP/3. Lutske de Leeuw & @parttimen3rd explain why boring wins.

🌕 VM Options Explorer：OpenJDK HotSpot 選項指南與歷史變遷
➤ 深入 JVM 內核，精準掌握虛擬機參數生命週期
✤ https://chriswhocodes.com/vm-options-explorer.html
本文介紹了一個名為「VM Options Explorer」的線上工具，旨在協助開發人員快速查詢與比對不同 OpenJDK 與 HotSpot 版本間的虛擬機（VM）參數。透過該工具，使用者可以精確查看各項參數的適用版本、生命週期（如是否已廢棄或移除）、數據類型以及具體功能描述。無論是針對 Alibaba Dragonwell、Amazon Corretto 還是 Azul Zulu 等多種發行版，開發者都能藉此工具深入瞭解 JVM 的底層運作機制，從而進行更有效的系統調優與效能監控。
+ 終於有一個整合式的查詢工具了！以前查 JVM 參數廢棄版本都要翻閱大量的 JDK 發行說明，現在查起來方便多了。
+ 這對於進行高併發系統優化非常有用。特別是能對比不同廠商（如 Co
