program-libs/account-checks/Cargo.toml (1)
3-3: Version bump is properly scoped; dependencies unchanged. The minor version increment (0.5.1 → 0.6.0) and stable dependency set indicate this is a safe update.program-libs/merkle-tree-metadata/Cargo.toml (1)
3-3: Version bump with coordinated internal dependency. The minor version update to 0.7.0 pairs well with light-compressed-account's matching bump (also to 0.7.0), with workspace-based version resolution ensuring consistency.program-libs/compressed-account/Cargo.toml (1)
3-3: Central crate version update with stable dependency chain. The 0.6.2 → 0.7.0 bump maintains backward compatibility while supporting dependent crates (merkle-tree-metadata, batched-merkle-tree, verifier) that reference it viaworkspace = true.program-libs/array-map/Cargo.toml (1)
3-3: Patch version bump is appropriately scoped. The 0.1.0 → 0.1.1 increment reflects a minor fix or improvement to this lightweight utility crate with minimal dependencies.program-libs/verifier/Cargo.toml (1)
3-3: The review comment assumes a version bump from 5.0.0 → 6.0.0, but git history shows this is the initial creation of thelight-verifiercrate at version 6.0.0 (commitccebc4b7adds it as a new file). There is no prior version to compare against, so concerns about undocumented breaking changes from a major version increment are not applicable. The backward compatibility comment on line 15 refers to feature aliasing (anchoras an alias forsolana), not version compatibility.Likely an incorrect or invalid review comment.
program-libs/concurrent-merkle-tree/Cargo.toml (1)
3-3: Add breaking change documentation for version 5.0.0 transition. The major version bump from 4.0.1 to 5.0.0 is coordinated between concurrent-merkle-tree and indexed-merkle-tree (which depends on it). However, no CHANGELOG, MIGRATION guide, or breaking change documentation exists in either crate. Without documentation of what changed between versions, downstream consumers cannot understand the required updates. Add a CHANGELOG.md or document breaking changes in the crate's documentation.⛔ Skipped due to learnings

3-3: Major version bump requires verification of breaking changes and downstream impact. The 4.0.1 → 5.0.0 increment signals breaking API changes. Coordinated with light-concurrent-merkle-tree (also 4.0.1 → 5.0.0), this version alignment is well-structured through workspace versioning, but the nature and scope of breaking changes should be documented and validated against all external dependents.program-libs/compressible/Cargo.toml (2)
3-3: Verify the version scheme change from 0.1.0 to 0.2.1.The version bump skips 0.2.0 and jumps to 0.2.1, which is unusual. Confirm this is intentional from the release script rather than a typo. Typically, a minor version bump would land on X.Y.0.
Additionally, the addition of description and license metadata aligns with standard Rust crate publication practices and looks good.
Also applies to: 5-6
16-36: Dependencies correctly follow program-libs isolation guideline.All dependencies leverage the workspace pattern and include only program-libs crates (light-account-checks, light-compressed-account, light-zero-copy, light-macros, light-program-profiler, light-heap, aligned-sized) and external crates. No programs or sdk-libs detected, which complies with the architectural constraint.
program-libs/ctoken-interface/Cargo.toml (3)
3-3: Version bump and metadata additions are straightforward.The patch version bump (0.1.0 → 0.1.1) is conventional, and the addition of description and license metadata follows standard Rust crate publication practices.
Also applies to: 5-6
54-54: Clarify the addition of "poseidon" feature to dev-dependency light-hasher.The dev-dependency for light-hasher now includes the "poseidon" feature alongside "keccak" and "sha256". Verify that this aligns with new test requirements or test enhancements in this crate. Additionally, the AI summary indicates a dev-dependency on light-ctoken-interface itself was removed—confirm this was intentional and that removing it doesn't break any test scenarios.
16-41: Dependencies correctly follow program-libs isolation guideline.All dependencies (main and dev) consist of program-libs crates and external dependencies only. No programs or sdk-libs present, which complies with architectural constraints.

Version bump requires verification of API stability with major verifier dependency change. The minor version update to 0.7.0 includes a major version bump in light-verifier (5.0.0 → 6.0.0). Since VerifierError is publicly re-exported in BatchedMerkleTreeError, any breaking changes to verifier's error type directly affect batched-merkle-tree's public API. Confirm that verifier 6.0.0's breaking changes do not alter VerifierError, and document the version coordination rationale.
🤖 Prompt for AI Agents
In program-libs/batched-merkle-tree/Cargo.toml around line 3, the version bump
to 0.7.0 coincides with light-verifier moving from 5.x to 6.0.0 and you must
verify and document that this major verifier change does not break the publicly
re-exported VerifierError in BatchedMerkleTreeError; check the light-verifier
6.0.0 changelog and source to confirm the VerifierError type, variants and
public API are unchanged, run cargo update -p light-verifier and cargo test to
catch type/compatibility failures, add a compatibility unit test that constructs
and matches BatchedMerkleTreeError containing a VerifierError instance, and if
any breaking change exists either pin light-verifier to 5.x in Cargo.toml or add
an adapter/re-export type in this crate to preserve the public API, then
document the verification and chosen decision in the crate CHANGELOG and add a
comment next to the version bump in Cargo.toml explaining the coordination with
light-verifier.
