v1.1.2

I have everything I need. Here are the release notes:

---

DLC DevKit (DDK) v1.1.2

This is a maintenance release focused on operational robustness. It makes the Postgres connection pool and Esplora client timeout configurable for production deployments, and hardens the release automation against incidental Cargo.lock drift. No breaking changes — this is a drop-in upgrade from 1.1.1.

Breaking Changes

None. v1.1.2 is fully backwards-compatible with v1.1.1. All new configuration is opt-in via environment variables with sensible defaults that preserve existing behavior.

New Features

No new public features in this release.

Bug Fixes

• Configurable Postgres connection pool & Esplora timeout (#167) — The Postgres connection pool size and the Esplora request timeout were previously hardcoded, which could lead to connection exhaustion or premature chain-query timeouts under production load. Both are now resolved from the environment at startup:

  • DATABASE_MAX_CONNECTIONS — maximum size of the Postgres pool (default: 5; raise to 20+ for production).
  • ESPLORA_TIMEOUT_SECONDS — Esplora client request timeout in seconds (default: 5).

  Each value falls back to its default when the variable is unset, unparseable, or zero, and the chosen pool size is now logged when the pool is created. New public constants DEFAULT_MAX_CONNECTIONS and DEFAULT_ESPLORA_TIMEOUT_SECS are exported for reference.

• Release script no longer fails on incidental Cargo.lock drift — cargo's per-crate publish verification can re-resolve dependencies and rewrite Cargo.lock after the release commit is made, dirtying the working tree and aborting the final switch back to master. The release script now discards this non-release drift and performs the branch switch best-effort, warning instead of failing once all crates are already published and pushed.

Other Notable Changes

• .env.sample updated to document the new DATABASE_MAX_CONNECTIONS and ESPLORA_TIMEOUT_SECONDS settings.
• Dependency updates — Cargo.lock refreshed with updated transitive dependencies.

Installation

Add DDK to your Cargo.toml:

[dependencies]
ddk = "1.1.2"

Or via the command line:

cargo add ddk@1.1.2

All workspace crates are published at 1.1.2: ddk, ddk-manager, ddk-messages, ddk-dlc, ddk-trie, ddk-payouts, ddk-node, and kormir.

v1.1.0

Here are professional release notes for DDK v1.1.0:

---

DDK v1.1.0

This release introduces ZMQ-based block notifications for faster, push-driven chain monitoring, adds contract flag support for redirecting refunds to the accepter, and includes dependency updates and CI improvements.

⚠️ Breaking Changes

None. This is a backward-compatible minor release.

Note: The internal wait() function in ddk now accepts a ZMQ subscription parameter (refactor(ddk): pass zmq sub into wait function). This affects downstream code only if you call this function directly.

✨ New Features

• ZMQ block notifications (feat(ddk)) — DDK can now receive blockhash notifications over ZMQ instead of relying solely on polling, enabling lower-latency chain updates. A new ddk/src/chain/zmq.rs module powers this path. (#150)
• ZMQ node configuration (feat(ddk-node)) — ddk-node exposes configuration for the ZMQ blockhash notification endpoint, including a new ZMQ_BLOCKHASH_ENDPOINT setting (see .env.sample).
• Resilient ZMQ client (feat(ddk)) — the ZMQ client now logs and exits cleanly if its subscription fails, surfacing connection issues early instead of failing silently.
• Refund-to-accepter contract flags (feat) — added contract_flags support to redirect a contract's refund output to the accepter. (#157)

🐛 Bug Fixes

• ddk: pass the stop signal to the ZMQ client to ensure it shuts down correctly.
• ddk-node: ensure zmq_blockhash_endpoint has a value before use, preventing misconfiguration errors.
• ddk-node: pass the log argument to logger creation so logging is configured as expected.

🔧 Other Changes

• deps: updated workspace dependencies based on cargo audit findings to address advisories. (#156)
• ci: faster builds via improved caching and a corrected workspace version read from Cargo.toml. (#161, #162)
• ci: cleaned up and updated the release script (release.js). (#160)
• refactor(ddk): DRY'd up the poll/notification code paths and passed the ZMQ subscriber into wait() to avoid recreating subscribers on every loop iteration.
• tests: added coverage for ZMQ blockhash message handling.
• docs: noted to copy .env.example before running dependencies; minor spelling fixes.

v1.0.11

DLC Dev Kit v1.0.11

Summary

This release adds support for zero offer collateral in single-funded DLCs, enabling use cases where one party fully funds the contract while the other contributes no collateral.

New Features

• Zero offer collateral for single-funded DLCs — The collateral validation in ContractInput now permits an offer collateral of zero when using single-funded DLC channels. Previously, zero collateral was rejected by the input validation. (#153, thanks @matthewjablack)

Now I have all the context needed. Here are the release notes:

---

DLC Dev Kit v1.0.10

Summary

This release adds manual control over refund transaction broadcasting, improves the kormir oracle crate architecture with extracted free functions, removes hardcoded PostgreSQL credentials, and refreshes documentation across the workspace.

Breaking Changes

• Removed default PostgreSQL URL from ddk-node (#143): The --postgres-url argument in ddk-node no longer has a default value. You must now explicitly provide a connection string when using PostgreSQL storage.

New Features

• Manual refund transaction broadcasting (#151): Added refund_dlc() to the DDK API, allowing users to manually check and broadcast refund transactions for matured contracts. This gives applications more control over when refund transactions are broadcast rather than relying solely on automatic behavior.

Improvements

• Kormir oracle refactor (#130): Extracted enum and numeric oracle event operations into standalone public functions (create_enum_event, create_numeric_event, etc.) with comprehensive documentation and examples. This makes it easier to use kormir's oracle functionality without instantiating the full Oracle struct.

• Security: Removed hardcoded credentials (#143): Removed default PostgreSQL credentials (postgres://dlcdevkit:dlcdevkit@localhost:5433/ddk_one) from the ddk-node CLI options.

• Documentation updates (#148): Refreshed READMEs across the workspace including ddk, ddk-manager, ddk-node, kormir, payouts, dlc-messages, dlc-trie, and the root README.md.
