The standout fix came in [n8n 2.37.1](/release/rel_jpklpuygtGXcuJxAumEDC-n8n-2-37-1), which ensures OAuth2 token requests route through environment proxies in *every* process — a critical correction for self-hosted deployments behind corporate proxies, where previously only certain worker processes respected the proxy configuration, causing intermittent auth failures. The [2.36.7](/release/rel_oJxtiSwnDVj1pi-kkwWAC-n8n-2-36-7) patch focused on API correctness: it adapted the binary data endpoint to match expected response formats and began requiring a JSON content type on decorator routes that accept a body. The latter is a subtle behavioral change that could break custom integrations sending `application/x-www-form-urlencoded` payloads to those routes, so API consumers should verify their requests still pass. This release also included the first part of the distroless runner fix. The distroless runner saga continued with [2.37.3](/release/rel_5Ng8WtwHD8wWTyHu3JBvn-n8n-2-37-3), which staged the `libatomic` library into the minimal runner image. This library is required for certain atomic operations in compiled JavaScript addons, and its absence caused crashes in environments using native modules. The fix appears in both the current 2.37 line and the LTS-style 2.36 branch via [2.36.8](/release/rel_bldrP7WnmMdCnIRAsEipY-n8n-2-36-8), ensuring users on either track get the correction. The [2.37.2](/release/rel_iEzwqPZb017N2DPBJ59aG-n8n-2-37-4) release (same as 2.36.8's content) confirmed the staged library works. Rounding out the week, [2.37.0](/release/rel__cJETZmGv8ZUl2rX7pWOR-n8n-2-37-0) brought the Agent Node improvement to show disabled reasons on prompt-source options — a small UX win that saves users from guessing why a configuration option is greyed out. The [2.36.6](/release/rel_9K3gU5Me8dnPBbVfk63Bp-n8n-2-36-6) patch fixed the Instance AI landing page to properly display the personalization survey and community registration modal, which had been failing to appear for new users. ### Temporal's protobuf migration On the workflow orchestration side, Temporal's TypeScript SDK hit [v1.23.0](/release/rel_Uapri2Cl3UK1RXMI1DpNi-v1-23-0) with a major internal upgrade: `protobufjs` jumped to v8 and `protobufjs-cli` to v2. This is breaking because Temporal exposes generated protobuf message types as part of its public API — particularly through `@temporalio/proto` and the raw gRPC interfaces on `Client`. Most applications won't touch these types directly, but if you're doing advanced gRPC calls or inspecting wire-level messages, you'll need to recompile or adapt your type references. The upgrade also brings newer protobuf language features, so any custom proto definitions compiled against the older toolchain may need regeneration. ## Releases covered ### n8n - [n8n@2.37.1](https://releases.sh/release/rel_jpklpuygtGXcuJxAumEDC-n8n-2-37-1) - [n8n@2.36.7](https://releases.sh/release/rel_oJxtiSwnDVj1pi-kkwWAC-n8n-2-36-7) - [n8n@2.37.3](https://releases.sh/release/rel_5Ng8WtwHD8wWTyHu3JBvn-n8n-2-37-3) - [n8n@2.36.8](https://releases.sh/release/rel_bldrP7WnmMdCnIRAsEipY-n8n-2-36-8) - [n8n@2.37.4](https://releases.sh/release/rel_iEzwqPZb017N2DPBJ59aG-n8n-2-37-4) - [n8n@2.37.0](https://releases.sh/release/rel__cJETZmGv8ZUl2rX7pWOR-n8n-2-37-0) - [n8n@2.36.6](https://releases.sh/release/rel_9K3gU5Me8dnPBbVfk63Bp-n8n-2-36-6) ### Temporal - [v1.23.0](https://releases.sh/release/rel_Uapri2Cl3UK1RXMI1DpNi-v1-23-0)
