## Thinking Path
> - Paperclip is the control plane for autonomous AI companies.
> - Stable releases need a reviewer-readable changelog artifact that
summarizes what changed for operators and contributors.
> - The last stable release tag is `v2026.513.0`, and the requested
release date is 2026-05-17.
> - The release changelog skill maps that date to stable version
`2026.517.0` and requires the range `v2026.513.0..origin/master`.
> - I reviewed the commits, PR metadata, migration/API surfaces, and
contributor attribution in that range.
> - This pull request adds the `releases/v2026.517.0.md` changelog for
human release sign-off.
> - The benefit is a stable release note artifact that is ready to
review before publishing the release.
## What Changed
- Added `releases/v2026.517.0.md` for the 2026-05-17 stable release.
- Summarized user-facing highlights, improvements, fixes, and
contributor attribution from `v2026.513.0..origin/master`.
- Omitted Breaking Changes and Upgrade Guide sections after checking for
destructive migrations, removed API surfaces, and breaking-change commit
signals.
## Verification
- `./scripts/release.sh stable --date 2026-05-17 --print-version` ->
`2026.517.0`.
- `git tag --list 'v*' --sort=-version:refname | head -10` confirmed
`v2026.513.0` is the latest stable tag.
- `git log v2026.513.0..origin/master --oneline --no-merges` reviewed
the 16 release-range commits.
- `git diff --name-only v2026.513.0..origin/master -- .changeset`
returned no changeset files.
- `git log v2026.513.0..origin/master --format='%s' | rg -n 'BREAKING
CHANGE|BREAKING:|^[a-z]+!:' || true` returned no breaking-change
signals.
- `git diff --name-only v2026.513.0..origin/master --
packages/db/src/migrations packages/db/src/schema server/src/routes
server/src/api server/src` reviewed the DB/API/server touchpoints; only
an additive document-lock migration appeared in the DB schema/migration
path.
- `test -f releases/v2026.517.0.md` passed.
- `rg -n -- '-canary|canary/' releases/v2026.517.0.md || true` returned
no canary filename/title language.
- `git diff --cached --check` passed before commit.
## Risks
- Low risk: docs-only release changelog addition.
- Changelog grouping is editorial; reviewers may want wording or
prioritization changes before release publication.
- Contributor attribution intentionally excludes bot accounts and
Paperclip founders from the Contributors section per the release
changelog skill.
> Checked [`ROADMAP.md`](ROADMAP.md); this is release documentation, not
new roadmap-level core feature work.
## Model Used
- OpenAI Codex, GPT-5 coding agent via Paperclip `codex_local`, with
shell, git, GitHub CLI, and repository file editing enabled. Exact
backend sub-version and context window were not surfaced by the
Paperclip runtime.
