What is OpenMQTTGateway?

OpenMQTTGateway returns after 22 months with a security-first 1.9.0.

OpenMQTTGateway shipped v1.9.0 on November 7, its first release since January 2025. It moves to the Arduino ESP32 core 3.x, ships Theengs Decoder 2.5.0 with a fix for a BLE advertisement parsing flaw affecting every earlier release, and hardens buffer handling across MQTT, HTTP, BLE and RF input. Upgrade notes warn that some Home Assistant unique_ids change and that encrypted BLE devices are skipped until a key is set.

What is Ory Hydra?

Hydra's 2.2 candidates rebuilt the OAuth2 flow store, then reached for verifiable credentials

Ory Hydra is a self-hosted OAuth2 and OpenID Connect server. Its visible release record is the v2.2.0 candidate series from 2023, which did two substantial things: rc.2 moved authorization-code flow state out of the database and into AEAD-encrypted cookies and request parameters, a change shipped with an explicit breaking-change notice; rc.3 then added initial OIDC verifiable-credential issuance and wired logout propagation into Ory Kratos. The feed stops at a v2.2.0-pre.1 tag in February 2024.

OpenMQTTGateway returns after 22 months with a security-first 1.9.0.

◆ Current state

OpenMQTTGateway shipped v1.9.0 on November 7, its first release since January 2025. It moves to the Arduino ESP32 core 3.x, ships Theengs Decoder 2.5.0 with a fix for a BLE advertisement parsing flaw affecting every earlier release, and hardens buffer handling across MQTT, HTTP, BLE and RF input. Upgrade notes warn that some Home Assistant unique_ids change and that encrypted BLE devices are skipped until a key is set.

◆ Where it's heading

Earlier releases made the gateway independent of controllers and external brokers. The return release is about safety and a modern ESP32 base rather than new features, which suggests the project is resetting its foundation before resuming feature work.

◆ Prediction

Expect the promised security advisory for the Theengs Decoder flaw and 1.9.x fixes for the Home Assistant entity changes; whether regular cadence resumes is not yet clear from the entries.

Hydra's 2.2 candidates rebuilt the OAuth2 flow store, then reached for verifiable credentials

◆ Current state

Ory Hydra is a self-hosted OAuth2 and OpenID Connect server. Its visible release record is the v2.2.0 candidate series from 2023, which did two substantial things: rc.2 moved authorization-code flow state out of the database and into AEAD-encrypted cookies and request parameters, a change shipped with an explicit breaking-change notice; rc.3 then added initial OIDC verifiable-credential issuance and wired logout propagation into Ory Kratos. The feed stops at a v2.2.0-pre.1 tag in February 2024.

◆ Where it's heading

The through-line is reducing per-request database work in the hot authorization path — first by relocating flow state into encrypted client-side material, then by parallelizing JSON web key set generation and adding scope-claim strategies. Running underneath is tighter coupling to the rest of the Ory stack: the Kratos admin URL config and session-termination hook make Hydra less of a standalone component and more of one piece of an integrated identity suite. The verifiable-credentials work is the one thread pointing somewhere genuinely new, and it shipped against a draft specification.

◆ Prediction

The candidate series points toward a v2.2.0 general release consolidating the AEAD flow change and the credential-issuance work. The feed's silence after February 2024 gives no basis for judging when, or whether the draft-stage VC support advanced.
