| ### Changed |

| - Adopted the aligned version of datasets from <https://github.com/common-parallel-corpora/common-parallel-corpora>. Data is now aligned across all languages, i.e. all files use the same ordering of sentences. |
| - Data was NFC normalised. |
| - Updated `lij_Latn` after additional quality assessment. Data has undergone minor spelling and syntactic fixes. |
| - Relabeled `tzm_Tfng` to `zgh_Tfng` after additional quality assessment revealed the data was in Standard Moroccan Tamazight. Many thanks to @MedAymenF for pointing out the issues with the original NLLB-Seed data. |
| - Relabeled `grn_Latn` macrolanguage code to the correct code `gug_Latn`. |
