CHANGELOG

### Unreleased

* refactor: Deduplicate no-op WatchPrefix and Close across polling-only backends (2026-04-19) (#588)
  - Add `NoopWatcher` and `NoopCloser` embeddable structs to `pkg/backends/types`
  - Migrate all 7 polling-only backends (acm, dynamodb, env, imds, secretsmanager, ssm, vault) to embed both structs
  - Remove 14 identical method implementations; polling-only nature of each backend is now explicit via the embedded type names
  - Closes #550

* chore(deps): bump github.com/aws/aws-sdk-go-v2/config from 1.32.13 to 1.32.16 (#585)
* chore(deps): bump github.com/aws/aws-sdk-go-v2/service/ssm from 1.68.4 to 1.68.5 (#584)
* chore(deps): bump go.etcd.io/etcd/client/v3 from 3.6.8 to 3.6.10 (#583)

* chore(deps): bump github.com/aws/aws-sdk-go-v2 from 1.41.5 to 1.41.6 (#581)

* perf: Skip stage file write when rendered content is unchanged (2026-04-19) (#586)
  - Add `contentUnchanged()` to `fileStager`: compares rendered bytes against dest file (mode + ownership + size + MD5) before staging
  - Refactor `process()` to render first, check `contentUnchanged()`, and early-return without staging on the no-change path
  - Eliminates temp file create/write/rename/delete on the common steady-state no-change path
  - Closes #548

* refactor: Extract shared AWS SDK init helper into awsutil package (2026-04-19) (#587)
  - Add `pkg/backends/awsutil.LoadAWSConfig` centralizing region detection (env → IMDS → SDK defaults), config loading, and credential validation
  - Migrate acm, ssm, secretsmanager, and dynamodb backends to use the shared helper, removing ~120 lines of duplicated boilerplate
  - Add `dialTimeout` parameter to `dynamodb.NewDynamoDBClient` for consistency with other AWS backends
  - Closes #549

* chore: Ignore root-level confd binary in .gitignore (2026-04-18) (#580)

* fix: Handle os.Remove errors when cleaning stage files (2026-04-18) (#579)
  - Replace all bare `os.Remove` calls on stage files with `removeStageFile` helper
  - Silently ignore `ErrNotExist` (expected after atomic rename), log Warning for other errors
  - Add `stage_file_cleanup_errors_total` Prometheus counter for observability
  - Move `removeStageFile` to `file_stager.go` alongside all other staging logic
  - Extend metrics tests to cover `StageFileCleanupErrors` initialization and recording
  - Closes #556

* fix: Resolve gosec code scanning alerts (2026-04-18) (#578)
  - Suppress false positives with `#nosec` annotations for G117, G204, G304, G703, G115 — all operator-configured paths/commands or internal-only hash input
  - Handle previously unhandled errors from `Close()` and `os.Remove()` calls in redis, vault, and template packages with warning/error logging
  - Extract `closePubSubLocked()` and `removeStageFile()` helpers to deduplicate repeated cleanup patterns

### v0.41.0 (2026-04-18)

* fix: Windows support — skip chown and owner/group lookup on Windows (#574)
  - `os.Chown` is unsupported on Windows; `chownFile` is now a no-op on Windows
  - `user.Lookup`/`user.LookupGroup` return SID strings on Windows that cannot be
    parsed as numeric IDs; `resolveOwnership` skips user/group lookup on Windows
    and logs a warning if `owner`/`group` are set in the template config
  - Add `cross-platform.yml` CI workflow running unit tests on `windows-latest`
    and `macos-latest`

* fix: Non-blocking errChan sends in monitorPrefix and monitorForBatch — prevents watch goroutines from stalling under error bursts when all backends fail simultaneously; dropped errors are logged at Warning level (#560)

* fix: Propagate context through Vault and Zookeeper GetValues — `--backend-timeout` and caller cancellation now take effect for Vault (updated vaultLogical interface to use `*WithContext` variants) and Zookeeper (goroutine+select wrappers for blocking calls) (#566)

* fix: Close cached per-resource backend clients on shutdown — prevents connection/resource leaks when template resources override the global backend; lock is released before Close() to prevent deadlock (#564)

* perf: Cache template resources across interval cycles — eliminates per-tick filesystem walk, TOML parse, and TemplateResource construction in intervalProcessor; resources loaded once at startup, reloaded only on SIGHUP (#553)
* perf: Replace time.After with time.NewTicker in intervalProcessor — avoids per-tick timer allocation and timer goroutine leak on shutdown (#553)

* feat: Add 28 utility template functions (#272)
  - Defaults & conditionals: `default`, `ternary`, `coalesce`, `empty`
  - JSON: `toJson`, `fromJson`, `toPrettyJson`
  - Formatting: `indent`, `nindent`, `quote`, `squote`
  - Regex: `regexMatch`, `regexFind`, `regexReplaceAll`
  - Strings: `trimPrefix`, `repeat`, `nospace`, `snakecase`, `camelcase`, `kebabcase`
  - Collections: `dict`, `list`, `hasKey`, `keys`, `values`, `append`, `pluck`
  - Hashing: `sha256sum`

### v0.40.0

This release represents a significant evolution of confd with major architectural improvements, new features, and performance optimizations. The version jump from v0.33.0 to v0.40.0 reflects the scope of these changes.

**BREAKING CHANGES**:

* **CLI migrated to Kong with backend subcommands**: The CLI now uses `confd <backend> [flags]` syntax instead of `confd --backend=<backend>`. For example, `confd --backend=etcd --node=http://localhost:2379` becomes `confd etcd --node=http://localhost:2379`. (#357)

* **Logging migrated from logrus to slog**: confd now uses Go's standard library `log/slog` for structured logging. Log output format has changed. Use `--log-format=json` for machine-parseable logs. (#420)

* **Redis client migrated from redigo to go-redis/v9**: Internal implementation change that may affect connection behavior. (#376)

**New Features**:

* feat: Add AWS EC2 IMDS backend for Instance Metadata Service v2 (#431)
* feat: Add Prometheus metrics and observability instrumentation (`--metrics-addr`) (#416)
* feat: Add health check endpoints (`/health`, `/ready`, `/ready/detailed`) (#429)
* feat: Standardize HealthCheck implementations across all backends (#427)
* feat: Add error aggregation and failure modes (`--failure-mode=best-effort|fail-fast`) (#426)
* feat: Extract hardcoded timeouts and retry delays to configuration flags (#425)
* feat: Add `templates_loaded` and `watched_keys` gauge metrics (#424)
* feat: Add structured logging with timing metrics to critical paths (#420)
* feat: Add template compilation caching for improved performance (#368)
* feat: Add per-resource backend configuration support (#359)
* feat: Add configuration validation, template enhancements, and watch mode improvements (#360)
* feat(redis): Implement exponential backoff for connection retries (#405)
* feat: Add official Docker images published to Docker Hub and GHCR (#463)
* feat: Multi-architecture Docker support (linux/amd64, linux/arm64)
* feat(packaging): Add RPM and DEB package support via nFPM (#520)
* feat(cli): Add comprehensive environment variable support (#516)

**Performance Improvements**:

* perf: Use conditional defer in process() to avoid overhead when metrics disabled (#462)
* perf: Pool map allocations in memkv List/ListDir operations (#461)
* perf: Optimize IsConfigChanged to reduce syscalls (#460)
* perf: Avoid FuncMap copy on every include call (#459)
* perf: Add TTL-based caching for template file stat checks (#458)
* perf: Cache prefixed keys on TemplateResource initialization (#457)
* perf: Pre-compile command templates in CommandExecutor (#456)
* perf: Pre-allocate template slice in getTemplateResources (#454)

**Bug Fixes**:

* fix: Address high severity bugs - goroutine leaks, FD leaks, data races (#493, #494, #496, #497)
* fix: File backend wildcard keys filtered out (#498)
* fix: Preflight now uses per-resource backend for key checks (#495)
* fix: Inject version from git tag at build time (#522)
* fix(redis): Support multiple prefixes in WatchPrefix (#510)
* fix(imds): Close response body in HealthCheck and New (#511)
* fix(imds): Avoid trailing slash in user-data cache key (#500)
* fix(backends): Respect context cancellation in WatchPrefix stubs (#512)
* fix(template): Use atomic.Bool for reloadRequested to prevent data race (#504)
* fix(template): Reduce backend fetch log verbosity (#506)
* fix(config): Return error for invalid duration values in confd.toml (#505)
* fix(zookeeper): Propagate errors from recursive nodeWalk calls (#499)
* fix: Exclude timeout fields from client cache hash (#455)
* fix(vault): Improve flatten() function type safety (#433)
* fix(redis): Add automatic reconnection for PubSub watch mode (#408)

**Refactoring**:

* refactor: Refactor TemplateResource to follow Single Responsibility Principle (#409)
* refactor: Propagate context.Context through backend calls (#379)
* refactor: Internalize memkv package from abandoned upstream (#369)
* refactor: Standardize error wrapping across codebase (#423)
* refactor(vault): Replace panic-based error handling with explicit error returns (#378)
* refactor(vault): Consolidate duplicate recursive listing functions (#404)

**Testing**:

* test(template): Add integration tests for watch reconnection after backend failures (#519)
* Comprehensive integration test suite reorganized into categorical structure (#432)
* Test coverage improved significantly across all backends
* Added integration tests for health, metrics, failure modes, includes, and signals (#430)

**Infrastructure**:

* Update Go version to 1.25 (#415)
* Numerous dependency updates for security and compatibility

### v0.33.0

* feat: Add AWS Secrets Manager backend support (#356)
* feat: Migrate AWS backends from SDK v1 to v2 (#355)
* feat: Add private key export support for ACM backend (#329)
* feat: Add AWS ACM backend support (#328)
* chore: Add benchmark suite for template and backend performance (#353)
* chore: Code quality cleanup and godoc improvements (#352)
* fix: Update Makefile for goreleaser v2 compatibility

### v0.32.0

**BREAKING CHANGE**: The global `prefix` setting in `confd.toml` is now concatenated with resource-level `prefix` values in template resource files (`conf.d/*.toml`) instead of overriding them. For example, if `confd.toml` has `prefix = "production"` and a resource has `prefix = "myapp"`, the effective prefix is now `/production/myapp` instead of `/production`. To restore the previous behavior, remove the `prefix` setting from your template resource files. (#324)

* feat: Add JSON log format support via `--log-format` flag (#327)
* feat: Add template variable support (`{{.src}}`, `{{.dest}}`) in `reload_cmd` (#326)
* docs: Update CHANGELOG with releases v0.19.2 through v0.31.1 (#325)
* chore: Fix goreleaser v2 deprecation warnings

### v0.30.0

**BREAKING CHANGE**: Vault KV v2 configurations that include `/data/` in the key path are no longer supported. The Vault backend now properly handles the `/data/` path component internally. Use `prefix` for the Secrets Engine path instead.

* refactor: Broadly refactor Vault client to properly handle KV v1 and KV v2 (#270)
