 ## 0.9.48 (2026-08-20)
 
+- Feature: Microsoft Dynamics 365 Business Central AL (`.al`) extraction now models application objects, permission sets and extensions, ControlAddIns and hosted UserControls, procedures and overloads, scoped field/action/UserControl triggers, fields, enum values, extensions, interfaces, typed calls, ControlAddIn event bindings, event subscriptions, enum implementations, application dependencies, TestPage targets, and test handler bindings with case-insensitive cross-file resolution. Install the optional `[al]` extra for full Tree-sitter extraction on Python 3.12+; other supported Python versions retain structural object/procedure/trigger extraction through the built-in fallback.
 - Fix: a control character in a node label or id no longer aborts the whole export; the GraphML and Obsidian exporters scrub only the characters those formats forbid (tab, newline, and non-ASCII letters are preserved), and `graph.json` and its byte-identity round-trip are untouched (#2897, thanks @abhay-codes07).
 - Fix: `graphify update` / `label` / `cluster-only` no longer leave a large graph without a `graph.html`; the aggregated community view renders instead of raising, a failed render preserves the previous file, and a missing `graph.html` is regenerated on the no-change fast path without reclustering (#2853, thanks @oleksii-tumanov).
 - Feature: `graphify extract --no-dedup` skips the fuzzy near-duplicate merge on build and incremental merge, for operators who would rather keep distinct symbols that fuzzy-matched; exact-id uniqueness is unaffected and the flag arms the shrink guard so a surprising node drop is refused loudly (#2881, thanks @rajarshidattapy).
