 ## Unreleased
 
-### `Changed`
+### `Added`
 
 - Added RASUSA for down sampling of Nanopore or PacBio data. [PR 125](https://github.com/phac-nml/mikrokondo/pull/125)
 
+- Added a new field to the `schema_input.json` file to allow for sample ID's from external systems such as IRIDA Next: [PR 140](https://github.com/phac-nml/mikrokondo/pull/140)
+
+- Incorporated a `--skip_read_merging` parameter to prevent read merging [PR 140](https://github.com/phac-nml/mikrokondo/pull/140)
+
+### `Changed`
+
+- Added a `sample_name` field, `sample` still exists but is used for different purposes [PR 140](https://github.com/phac-nml/mikrokondo/pull/140)
+
+- RASUSA now used for down sampling of Nanopore or PacBio data. [PR 125](https://github.com/phac-nml/mikrokondo/pull/125)
+
+- Sample names (`sample_name` field) can no longer begin with a period. [PR 125](https://github.com/phac-nml/mikrokondo/pull/125)
+
 ### `Updated`
 
 - Documentation and workflow diagram has been updated. [PR 123](https://github.com/phac-nml/mikrokondo/pull/123)

 Numerous steps within mikrokondo can be turned off without compromising the stability of the pipeline. This skip options can reduce run-time of the pipeline or allow for completion of the pipeline despite errors.
 ** All of the above options can be turned on by entering `--{skip_option} true` in the command line arguments to the pipeline (where optional parameters can be added)**
 
+
+- `--skip_read_merging`: Do not merge reads, if duplicate sample names are present the names will be made unique.
 - `--skip_abricate`: turn off abricate AMR detection
 - `--skip_bakta`: turn off bakta annotation pipeline (generally a slow step, requiring a database to be specified).
 - `--skip_checkm`: used as part of the contamination detection within mikrokondo, its run time and resource usage can be quite lengthy.
