Release v28.0.0 - #929

Conversation
The train has run its integration legs against stellar/unsafe-stellar-core because the GA docker repo lags the GitHub release by days. Both 28.0.0-3494.a9b861321.jammy and .noble are now published under stellar/stellar-core, so the release legs pin the GA repo. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Pull request overview
Promotes Protocol 28 integration tests from the unsafe Stellar Core image repository to the GA repository.
Changes:
- Updates P27 and P28 integration legs to use the GA Core image.
- Keeps existing Core version and Debian package pins unchanged.
💡 Add a code-review agent skill or configure MCP servers for context-aware, tailored reviews. Learn more in the docs.
… cut The v28.0.0 section landed with #913, when the release branch pointed at the protocol-next merge. Re-syncing to main brought in #854 (backfill bulk-load) and #928 (dependency bump + slimmer release image), so the section now names them.

All three Protocol 28 platform repos now ship against the same released SDK tag. v0.7.2 was cut from SDK main because Horizon's release branch was pinning a pseudo-version to get the XDR asset ordering fix; taking the tag here keeps rpc, Horizon and Galexie on identical SDK code for GA. On top of v0.7.0 this brings SEP-23 strkey payload length validation (go-stellar-sdk#5977), protocol-order asset comparison (go-stellar-sdk#5974), the txnbuild liquidity pool ordering guards (go-stellar-sdk#5978), v0.7.1's ingest single-ledger-walk extraction and a transitive go-xdr bump. Unit tests (including the cgo-linked methods, preflight and xdr2json packages) pass locally against the new pin. Note: this supersedes the 28.0.0-204 staging artifacts, which were built at 9758b75 — the RC deb and image need rebuilding from this commit before the staging sign-off counts.

Protocol 28 GA release for stellar-rpc. Tracking issue: stellar/go-stellar-sdk#5967.
The release branch is synced with
main(fast-forward — it carried no uniquecommits), so the only branch-unique change here is the CI core-image swap:
stellar/unsafe-stellar-core:28.0.0-3494.a9b861321.jammy→stellar/stellar-core:28.0.0-3494.a9b861321.jammyon both integration legs.The train ran on the
unsaferepo because the GA docker repo lags the GitHubrelease;
stellar/stellar-corenow publishes the same build (jammy + noble).The deb pins are unchanged — apt has no unsafe/GA split.
The CHANGELOG's
v28.0.0section already landed onmainvia #913.Merge gate: staging sign-off on the dev-eks deployment (stellar/kube#4823).
Merging this PR is stage 2 of the release — its merge commit is the
v28.0.0tag target.
