 ### Enhancements & fixes
 
 - [[#878](https://github.com/nf-core/rnaseq/pull/878)] - Allow tabs in fasta header when creating decoys for salmon index
+- [[#931](https://github.com/nf-core/rnaseq/pull/931)] - Save transcriptome BAM files when using `--save_umi_intermeds` / `--save_align_intermeds`
 - [[#934](https://github.com/nf-core/rnaseq/pull/934)] - Union of `ext.args` and `params.extra_star_align_args` prevents parameter clashes in the STAR module
 - [[#940](https://github.com/nf-core/rnaseq/issues/940)] - Bugfix in `salmon_summarizedexperiment.r` to ensure `rbind` doesn't fail when `rowdata` has no `tx` column. See ([[#941](https://github.com/nf-core/rnaseq/pull/941)]) for details.
 - [[#944](https://github.com/nf-core/rnaseq/issues/944)] - Read clipping using clip_r1, clip_r2, three_prime_clip_r1, three_prime_clip_r2 disabled in 3.10
