-# v0.6.0
-*   feat: Introduce Model Context Protocol (MCP) server with a demo random fact tool.
-*   feat: Add MCP server configuration file (`contrib/mcpinspector.json`).
-*   deps: Update Go module dependencies, including `bufbuild/protovalidate`, `go-app`, `grpc-gateway`, `googleapis/api`, `grpc`, `protobuf`, `golang.org/x/exp`, and `googleapis/rpc`.
-*   deps: Add new Go module dependencies: `modelcontextprotocol/go-sdk` and `k8s.io/utils`.

-# v0.5.0
+## [v0.2.0] - 2026-07-05
 
-*   Added OpenTelemetry tracing for application startup.
-*   Updated Go module dependencies, including `protovalidate`, `go-app`, `grpc`, and OpenTelemetry related packages.
-*   Enhanced `Makefile` `rename` target to update the application name constant in `main.go`.
-*   Configured `air` live-reloading to exclude the `proto` directory.
-*   Refactored application initialization logic for improved modularity and OpenTelemetry integration.
+### Added
+
+* `econetTLSInsecure` config option (env `ECONET_TLS_INSECURE`) to skip TLS
+  certificate verification when
+  connecting to the Rheem/EcoNet cloud API. The upstream host (cloudblade)
+  serves an old/untrusted certificate chain; this is a stopgap and should be
+  removed once the upstream certificate is fixed. See AGENTS.md.
+* `TODO.md` tracking outstanding work (CA cert bundle, mutating proto RPCs,
+  additional tracing spans).
+
+## [v0.1.2] - 2026-07-04
+
+### Added
+
+* CA certificate bundle baked into the container image so the exporter can
+  establish TLS connections to the EcoNet API.
+
+### Changed
+
+* Bumped Helm chart versions.
+
+## [v0.1.1] - 2026-07-04
+
+### Fixed
+
+* Corrected the Helm chart `appVersion`.
+
+## [v0.1.0] - 2026-07-04
+
+Initial release of the EcoNet exporter for Rheem / Rheemcloud water heaters,
+built on the `go-app` framework.
+
+### Added
+
+* `EconetService` owning a single shared `*rheemcloud.Client` across the gRPC,
+  MCP, and metrics sub-servers (fail-fast on missing credentials).
+* gRPC API (`ListDevices`, `GetDevice`) with proto definitions and
+  grpc-gateway REST bindings.
+* MCP server at `/api/mcp` exposing a `list_water_heaters` tool.
+* OpenTelemetry observable gauges for device state (temperature, mode, energy
+  and water usage, cost) with a background usage poller, exported to
+  Prometheus. Units are encoded in metric names (`_fahrenheit`, `_kwh`,
+  `_gallons`, `_dollars`).
+* `costPerKWH` config (US dollars per kWh) feeding `econet_energy_cost_dollars`.
+* Helm chart for Kubernetes deployment.
