+## v4.1.0 - [2026-02-09]
+
+### Added
+
+- Added a BAM/CRAM conversion to FASTQ step to run tools that depend on FASTQ files. It still is advised to supply a FASTQ file if possible to reduce runtime of the pipeline. [#783](https://github.com/nf-core/rnafusion/pull/783)
+
+### Fixed
+
+- Fix issue with vcf_collect when no fusions are found by fusioninspector [#786](https://github.com/nf-core/rnafusion/pull/786)
+
 ## v4.0.0 - [2025-09-10]
