Week of November 2, 2026

What shipped

Why it matters

This week brings a new core release plus a conversion fix for profiles whose sample labels carry a bytes key, which previously leaked into OTLP sample attributes. The web and profile packages also received new published versions for those who depend on them directly.

Post for X

Parca v0.30.0 is out with dependency updates. Also merged: a fix that drops only the bytes key from pprof sample labels during OTLP conversion. New @parca/web and @parca/profile versions published.

Post for LinkedIn

Parca v0.30.0 has been released, including dependency updates such as grpc-gateway v2.30.0 and the prometheus go-grpc-middleware providers at v1.1.1. Alongside the release, a fix was merged that drops only the bytes key from pprof string labels, numeric labels and their unit metadata immediately before OTLP conversion, so memory profiles with sample labels like bytes=123 no longer carry that key into OTLP sample attributes. New versions of @parca/web and @parca/profile were also published.

Week of October 26, 2026

What shipped

Why it matters

People running Parca on ARM nodes were getting a published ARM64 image whose shell failed with exec format error, because the runtime base stayed x86-64. The build change makes the per-target runtime image resolve correctly. The new OTLP forwarding mode gives users a way to send converted profiles to an OTLP-only upstream over gRPC, with target and external labels mapped to resource attributes.

This week: a build fix so the runtime image resolves the right base per target platform, no more exec format errors from an x86-64 shell in the ARM64 image. Also new: an OTLP profile forwarding mode that converts pprof and exports over gRPC.

Post for LinkedIn

This week in Parca: the runtime image build now declares the target platform before the base image, so Podman resolves the correct runtime base per target. Previously the published ARM64 image paired an ARM64 Parca binary with an x86-64 BusyBox, and /bin/sh failed with exec format error on ARM nodes. We also added an OTLP profile forwarding mode that converts scraped pprof profiles with the OpenTelemetry converter and exports them to an OTLP-only upstream over gRPC, mapping target and external labels to resource attributes.

Week of October 19, 2026

What shipped

Why it matters

This week brings an opt-in change to debuginfo uploads: collectors can now negotiate several independent upload targets instead of proxying artifact bytes, while legacy clients still receive the singular instructions they expect. Alongside that, seven packages across the web, store, profile, components, client, utilities and hooks libraries were published at new versions.

Post for X

Debuginfo uploads can now be negotiated as independent targets: opt-in clients send supports_multiple_uploads, receive repeated upload_targets with retry_required hints, and legacy clients keep the singular flow. Also out this week: @parca/web 0.16.1059, @parca/store 0.16.211, @p

Post for LinkedIn

Debuginfo upload negotiation now supports multiple backends. Opt-in collectors can send a capability flag, receive a list of upload targets and a retry hint, and upload artifacts independently without proxying bytes through Parca. Clients that do not opt in still get the singular upload instructions, so existing setups are unchanged. This week also published new versions of @parca/web (0.16.1059), @parca/store (0.16.211), @parca/profile (0.19.164), @parca/client (0.17.25), @parca/components (0.16.425), @parca/utilities (0.0.134) and @parca/hooks (0.0.129).
