1.2.15

Device IDs containing literal % characters (e.g., "202BC1-CODA%2D5519-000000")
are double-encoded in URLs. Mithril 2.3.8 incorrectly double-decodes route
parameters, corrupting device IDs with special characters.

Workaround: Extract device ID directly from window.location.hash and decode
once to get the correct value.

See: https://github.com/MithrilJS/mithril.js/issues/3064

 # Change Log
 
+## 1.2.15 (2026-03-26)
+
+- Fix critical RCE vulnerability in /api/ping endpoint (follow-up to
+  CVE-2021-46704). Credit: JuHwiSang.
+
+- Fix device IDs containing special characters (e.g., %) not being handled
+  correctly in the UI due to a regression in Mithril 2.3.8.
+
+## 1.2.14 (2026-03-12)
+
+- Prevent UI crash when a malformed URL is sent to the server.
+
+- Fix potential edge-case bugs in expression evaluation and session
+  serialization.
+
 ## 1.2.13 (2024-06-06)
 
 - Increase connection timeout for UI and NBI from 30 to 120 seconds to avoid
