 ## Fixed
 
+- (#2397) Fixed tags and same-note heading links such as `[[#Installation]]` being rendered as task links in Reading View when the note is a task. Thanks to @hm-24 for reporting this.
+
 - (#2389) Added the missing public [v4-to-v5 beta upgrade guide](https://tasknotes.dev/migration-v4-to-v5/), including synced-device and metadata-recovery instructions, and corrected the HTTP API authentication documentation. Thanks to @m4to-3pe for reporting the broken link.
 
 - (#2382) Fixed Kanban settings being ignored in existing `.base` files when nested under `options:` or `config:`, including empty-column hiding and pinned columns. Newly generated default files and exported v3 views now write settings directly on each view; existing files remain unchanged. See [Kanban View](https://tasknotes.dev/views/kanban-view/#configuration). Thanks to @techwiththiru for reporting this.
