# Checklist for submitter
If some of the following don't apply, delete the relevant line.
- [ ] Changes file added for user-visible changes in `changes/`,
`orbit/changes/` or `ee/fleetd-chrome/changes`.
See [Changes
files](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/guides/committing-changes.md#changes-files)
for more information.
- [ ] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements), JS
inline code is prevented especially for url redirects, and untrusted
data interpolated into shell scripts/commands is validated against shell
metacharacters.
- [ ] Timeouts are implemented and retries are limited to avoid infinite
loops
- [ ] If paths of existing endpoints are modified without backwards
compatibility, checked the frontend/CLI for any necessary changes
## Testing
- [x] Added/updated automated tests
- [ ] Where appropriate, [automated tests simulate multiple hosts and
test for host
isolation](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/reference/patterns-backend.md#unit-testing)
(updates to one hosts's records do not affect another)
- [x] QA'd all new/changed functionality manually
## Database migrations
- [x] Checked schema for all modified table for columns that will
auto-update timestamps during migration.
- [x] Confirmed that updating the timestamps is acceptable, and will not
cause unwanted side effects.
- shouldn't update timestamps unless the installer was a duplicate
- [x] Ensured the correct collation is explicitly set for character
columns (`COLLATE utf8mb4_unicode_ci`).
## New Fleet configuration settings
- [ ] Setting(s) is/are explicitly excluded from GitOps
If you didn't check the box above, follow this checklist for
GitOps-enabled settings:
- [ ] Verified that the setting is exported via `fleetctl
generate-gitops`
- [ ] Verified the setting is documented in a separate PR to [the GitOps
documentation](https://github.com/fleetdm/fleet/blob/main/docs/Configuration/yaml-files.md#L485)
- [ ] Verified that the setting is cleared on the server if it is not
supplied in a YAML file (or that it is documented as being optional)
- [ ] Verified that any relevant UI is disabled when GitOps mode is
enabled

## Summary by CodeRabbit
* **New Features**
* Software titles can now include multiple custom packages without
duplicating the title in lists.
* Added clearer package details when viewing software tied to a title or
team.
* **Bug Fixes**
* Improved installer conflict handling so uploads now show more specific
error messages.
* Prevented duplicate package entries from creating extra title rows or
incorrect counts.
* Fixed package counting and selection so the first-added package is
used consistently when multiple exist.
* **Chores**
* Added database changes to enforce the new package-deduplication
behavior.
