Walkthrough

This pull request updates Holochain dependency versions across documentation pages, bumping hdk from 0.5.5 to 0.5.6 and hdi from 0.6.5 to 0.6.6, introduces holo_hash at 0.5.6 with hashing feature enabled, adds crate-type configuration to Cargo.toml snippets, and refreshes build metadata timestamps.

Changes

Cohort / File(s)	Summary
Build & Dependency Documentation src/pages/build/identifiers.md, src/pages/build/zomes.md	Updated workspace dependencies: hdk bumped to 0.5.6, hdi bumped to 0.6.6, introduced holo_hash at 0.5.6 with hashing feature. Added crate-type = ["cdylib"] in integrity zome snippet.
Getting Started Guides src/pages/get-started/3-forum-app-tutorial.md, src/pages/get-started/install-advanced.md	Updated Holochain version references from 0.5.5 to 0.5.6 in code examples and build info. Updated hdk_version_req, hdi_version_req, and cargo_pkg_version. Refreshed build metadata timestamp to 2025-09-03T19:47:10.256511347Z.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Homogeneous changes: primarily version number updates across documentation files
• Low complexity: straightforward dependency bumps and metadata updates
• Minor addition: holo_hash introduction and crate-type configuration are well-scoped
• No logic changes or behavioral modifications

Possibly related PRs

• Chore: update docs to 0.5.5 #598: Both PRs modify the same documentation files to bump Holochain-related dependency versions and align holo_hash and hdi/hdk workspace entries.

File: src/pages/get-started/install-advanced.md:74-81
Timestamp: 2025-08-28T23:39:06.675Z
Learning: hc-launch may show older Holochain version dependencies (like "holochain 0.5.3") even when other tools show newer versions (like 0.5.5) because hc-launch is only repackaged when necessary for compatibility, not automatically with every Holochain release.

Timestamp: 2025-09-11T13:19:23.020Z
Learning: In the holochain/docs-pages repository, pdaoust prefers glossary definitions to be "future-correct" rather than strictly reflecting current implementation status, to reduce maintenance burden when features are implemented.

Timestamp: 2025-07-31T17:05:08.265Z
Learning: pdaoust prefers to ignore the MD047 rule (files should end with a single newline character) in the holochain/docs-pages repository because it's not applicable to the admonition plugin they're using.

🔇 Additional comments (7)

src/pages/get-started/3-forum-app-tutorial.md (1)

327-327: Version bump reflected correctly in documentation example.

Expected CLI output updated from holochain 0.5.5 to holochain 0.5.6.

src/pages/build/identifiers.md (2)

168-172: Workspace dependency versions correctly bumped.

Versions updated: hdi 0.6.5 → 0.6.6, hdk 0.5.5 → 0.5.6, and holo_hash introduced at 0.5.6.

---

180-180: holo_hash 0.5.6 is available and compatible with hdk 0.5.6—no action needed.

holo_hash v0.5.6 is published on crates.io and is the matching 0.5.x series for HDK 0.5.6, so the addition of holo_hash = { workspace = true, features = ["hashing"] } is correct and properly aligned with the ExternalHash use case.

src/pages/build/zomes.md (2)

73-78: Addition of crate-type and version bumps are correct.

The crate-type = ["cdylib"] addition to the [lib] section is appropriate for WASM library compilation. Dependency versions correctly updated: hdi 0.6.6, serde 1.0.

---

103-104: Coordinator zome dependencies correctly specified.

Version bump from hdk 0.5.5 to 0.5.6 is consistent with workspace declarations in other files.

src/pages/get-started/install-advanced.md (2)

78-80: Version strings updated consistently for 0.5.6 release.

All three Holochain components (CLI, terminal, holochain) show 0.5.6 in the expected output.

---

84-88: Build metadata correctly updated to reflect 0.5.6 versions.

Build info JSON now shows: cargo_pkg_version: 0.5.6, hdk_version_req: 0.5.6, hdi_version_req: 0.6.6. Timestamp appropriately updated to 2025-09-03T19:47:10.256511347Z.
