# Context
https://gitlab.com/groups/gitlab-org/-/epics/17482#note_2570525962
The design of the Commit list is being updated in https://gitlab.com/groups/gitlab-org/-/epics/17482. The design introduces a new layout for the commit details of each individual commit.
| Current | New https://gitlab.com/groups/gitlab-org/-/epics/17482 |
|---------|--------------------------------------------------------|
|  |  |
> currently, we reuse the commit list item here on MR commits page and last commit block on blob page. is the plan to update those as well?
Since we are updating the presentation of the commit list details block, other areas where this block is being used should be updated / redesigned as well:
| Commits page | Last commit block | MR commits page |
|--------------|-------------------|-----------------|
| {width=979 height=727} | {width=982 height=777} | {width=981 height=725} |
