 # Unreleased
 
+**Features**:
+- feat(js): Sourcemap debug IDs can now be read from the `"debugId"` field in addition to
+  `"debug_id"` ([#870](https://github.com/getsentry/symbolic/pull/870)).
+
 **Fixes**
 - Unship "Support for DWARFv5 embedded source code extension ([#849](https://github.com/getsentry/symbolic/pull/849))".
   Unfortunately the check for whether an elf file contains embedded sources is prohibitively expensive in terms of memory.
