The last three keep their own version streams and are tagged v0.10.0 to mark the train they shipped in, so the version column and the tag differ for them. The commit is what pins; the tag names the train.
The manifest pins all twelve modules the installer clones. The v0.9.0 manifest listed eight, so a pinned install of that train still resolved four modules at their default branch. Anyone reproducing v0.9.0 should be aware of that; v0.10.0 and every train after it pin the full set.
Tier 2 applications ride their own rails and are not part of this train. The current wallet release is 0.339.0.
Highlights
Consensus. The ledger amount precision flag day is pinned on mainnet at heights above each chain's tip, so a carrying fleet cannot open a retroactive window. The contract state sub-root is armed from genesis on every testnet. Batch cost weighting prices a chunk-carrier DEPLOY as a row write rather than a VM run, so it can share a batch with 249 companions instead of 220.
Indexer. Free-form user-text columns accept any legal UTF-8, closing a defect where one legal broadcast carrying a four-byte character could halt every indexer on the chain at the same block. Schema shape baselines are anchored to immutable origin fixtures, so a baselined shape can no longer be edited and re-frozen in a single commit with no migration. Anchor proofs are bound to the reward's own chain.
Hub. Oracle publishing and attestation relay reserve their spend budget before an awaited broadcast, so concurrent sends can no longer spend past the per-window ceiling. Every publisher refuses phase one of a two-transaction encoding before signing. A refused proposal consumes its rotation slot, so a hub that was not the leader for one slot can propose again. New read RPC for slash proposals, returning evidence as a digest rather than verbatim text.
Explorer. Detail pages for validators, XCALLs, attestations, polls and anchors. Seven new read surfaces for platform data that previously had none. A staking panel on the address page. A slash proposals surface that reads as accusation rather than verdict. The visual layer moves into a loadable theme token file.
SDK. verifyLockedBalance binds a served proof to the quorum-signed checkpoint, and locked-balance arming now gates on a caller-supplied trusted height rather than the server-echoed one. Identity binding on proof verification refuses a proof that answers a different address or tick. The static batch validator applies the weighted budget the chain actually charges.
Node. Pinned installs verify downloaded release artifacts against the pinned signing key. The explorer can run a self-synced checkpoint mirror for deployments with no colocated hub schema. A bootstrap source reporting no lag, or a negative lag, is refused rather than read as healthy.
Each component's CHANGELOG.md carries its full entry for this release.
Verifying this release
Every train tag is signed with the XChain Platform Release Signing key, RSA 4096, fingerprint 1DA7 C489 6F56 EA22 CF49 1EDF 4361 611A 82F9 0B70.

The assets are the pinned manifest, one source tarball per train member built at cut time from its tagged commit, and the digests with their detached signature. The tarballs are built during the ceremony rather than taken from GitHub's auto-generated archives, because those are not byte-stable over time.
Installing
xchain-node install v0.10.0
A pinned install resolves every component to the exact commit recorded in the manifest and verifies the artifacts after clone. install develop and install master remain tracking installs with no pins, for development.
Testing
Every component's full suite passed on its release branch, and the three-coin regtest end-to-end matrix, the action, security and performance suites across Bitcoin, Litecoin and Dogecoin, passed against the frozen commits with zero failures on all three coins.
