Sentry Release Management

Overview

Manage the full Sentry release lifecycle: create versioned releases, associate commits for suspect commit detection, upload source maps for readable stack traces, and monitor release health with crash-free rates and adoption metrics. Every production deploy should create a Sentry release so errors are grouped by version and regressions are caught immediately.

Prerequisites

• Sentry CLI installed: npm install -g @sentry/cli (v2.x) or use npx @sentry/cli
• Auth token with project:releases and org:read scopes from sentry.io/settings/auth-tokens/
• Environment variables set: SENTRY_AUTH_TOKEN, SENTRY_ORG, SENTRY_PROJECT
• Source maps generated by your build (e.g., tsc --sourceMap, Vite build.sourcemap: true)
• GitHub/GitLab integration installed in Sentry for automatic commit association (Settings > Integrations)

Instructions

Step 1 — Create a Release and Associate Commits

Choose a release naming convention. Sentry accepts any string, but two patterns dominate production usage:

Semver naming ties releases to your package version:

# Semver: my-app@2.1.0
VERSION="my-app@$(node -p "require('./package.json').version")"
sentry-cli releases new "$VERSION"

Commit SHA naming ties releases to exact deployments:

# SHA: my-app@a1b2c3d (short) or full 40-char SHA
VERSION="my-app@$(git rev-parse --short HEAD)"
sentry-cli releases new "$VERSION"

After creating the release, associate commits. This is what powers suspect commits — Sentry's ability to identify which commit likely caused a new issue by matching error stack frames to recently changed files:

# Auto-detect commits since last release (requires GitHub/GitLab integration)
sentry-cli releases set-commits "$VERSION" --auto

# Or specify a commit range manually
sentry-cli releases set-commits "$VERSION" \
  --commit "my-org/my-repo@from_sha..to_sha"

When --auto runs, Sentry walks the git log from the previous release's last commit to the current HEAD. It stores each commit's author, changed files, and message. When a new error arrives, Sentry matches the stack trace file paths against recently changed files and suggests the author as the likely owner.

Step 2 — Upload Source Maps and Release Artifacts

Source maps let Sentry translate minified stack traces into original source code. Upload them before deploying — Sentry does not retroactively apply source maps to existing events.

# Upload all .js and .map files from dist/
sentry-cli sourcemaps upload \
  --release="$VERSION" \
  --url-prefix="~/static/js" \
  --validate \
  ./dist

The --url-prefix must match how your JS files are served. The ~/ prefix is a wildcard that matches any scheme and host:

Your script URL	Correct --url-prefix
https://example.com/static/js/app.js	~/static/js
https://cdn.example.com/assets/bundle.js	~/assets
https://example.com/app.js (root)	~/

For multiple output directories (e.g., SSR apps):

sentry-cli sourcemaps upload \
  --release="$VERSION" \
  --url-prefix="~/" \
  ./dist/client ./dist/server

Managing release artifacts — list, inspect, and clean up uploaded files:

# List all artifacts for a release
sentry-cli releases files "$VERSION" list

# Delete all source maps for a release (free storage)
sentry-cli releases files "$VERSION" delete --all

# Upload a single file manually
sentry-cli releases files "$VERSION" upload ./dist/app.js.map

Build tool plugins (alternative to CLI uploads) — handle release creation, commit association, and source map upload automatically:

// vite.config.ts
import { sentryVitePlugin } from '@sentry/vite-plugin';

export default {
  build: { sourcemap: true },
  plugins: [
    sentryVitePlugin({
      org: process.env.SENTRY_ORG,
      project: process.env.SENTRY_PROJECT,
      authToken: process.env.SENTRY_AUTH_TOKEN,
      release: { name: process.env.VERSION },
      sourcemaps: {
        assets: './dist/**',
        filesToDeleteAfterUpload: ['./dist/**/*.map'],
      },
    }),
  ],
};

Step 3 — Finalize, Deploy, and Monitor Release Health

Finalize marks the release as complete. Until finalized, the release appears as "unreleased" in the UI:

sentry-cli releases finalize "$VERSION"

Finalizing affects three things: (1) issues resolved as "next release" are marked resolved, (2) the release becomes the baseline for future --auto commit detection, and (3) the activity timeline records the release.

Record the deployment to track which environments run which release:

sentry-cli releases deploys "$VERSION" new \
  --env production \
  --started $(date +%s) \
  --finished $(date +%s)

# For staging
sentry-cli releases deploys "$VERSION" new --env staging

Match the SDK release — the release string in your Sentry SDK init must match the CLI version exactly, or events will not associate with the release:

import * as Sentry from '@sentry/node';

Sentry.init({
  dsn: process.env.SENTRY_DSN,
  release: process.env.SENTRY_RELEASE,    // Must match CLI $VERSION exactly
  environment: process.env.NODE_ENV,
});

Release health dashboard — after deployment, monitor these metrics at sentry.io/releases/:

• Crash-free rate: Percentage of sessions without a fatal error. Target > 99.5%.
• Adoption: Percentage of total sessions running this release. Tracks rollout progress.
• Sessions: Total session count. A session begins when a user starts the app and ends after inactivity or a crash.
• Error count: New errors first seen in this release versus regressions.

Enable session tracking in the SDK for release health data:

Sentry.init({
  dsn: process.env.SENTRY_DSN,
  release: process.env.SENTRY_RELEASE,
  autoSessionTracking: true,   // Enabled by default in browser SDK
});

Cleanup old releases to manage storage and reduce noise:

# Delete a release and all its artifacts
sentry-cli releases delete "$VERSION"

# List all releases via API
curl -H "Authorization: Bearer $SENTRY_AUTH_TOKEN" \
  "https://sentry.io/api/0/organizations/$SENTRY_ORG/releases/"

Output

• Release created with a version identifier tied to semver or git SHA
• Commits associated for suspect commit detection and suggested assignees
• Source maps uploaded and validated for deobfuscated stack traces
• Release finalized with deployment environment and timestamps recorded
• SDK release value matching CLI version for event-to-release correlation
• Release health dashboard tracking crash-free rate, adoption, and session data

Error Handling

Error	Cause	Solution
error: API request failed: 401	Auth token invalid, expired, or missing project:releases scope	Regenerate at sentry.io/settings/auth-tokens/ with project:releases + org:read
No commits found with --auto	GitHub/GitLab integration not installed in Sentry	Install at Settings > Integrations > GitHub, then grant repo access
Source maps not resolving	--url-prefix does not match actual script URLs	Open browser DevTools Network tab, copy the script URL, and set --url-prefix to match the path portion
Stack traces still minified	Source maps uploaded after errors were captured	Upload source maps before deploying — Sentry does not retroactively apply them to existing events
release already exists	Re-creating a release that was already finalized	Non-fatal: use set-commits and sourcemaps upload to update it, or use a new version string
release not found in SDK events	Sentry.init({ release }) does not match CLI version	Print both values and compare — they must be identical strings (case-sensitive)
Crash-free rate not appearing	Session tracking disabled	Verify autoSessionTracking: true in SDK init (default in browser SDKs, must be enabled in Node.js)

See errors reference for additional troubleshooting.

Examples

Complete release script for CI/CD:

#!/bin/bash
# scripts/sentry-release.sh — run after build, before deploy
set -euo pipefail

VERSION="${1:-my-app@$(node -p "require('./package.json').version")}"
ENVIRONMENT="${2:-production}"

echo "Creating Sentry release: $VERSION → $ENVIRONMENT"

sentry-cli releases new "$VERSION"
sentry-cli releases set-commits "$VERSION" --auto
sentry-cli sourcemaps upload \
  --release="$VERSION" \
  --url-prefix="~/static/js" \
  --validate \
  ./dist
sentry-cli releases finalize "$VERSION"
sentry-cli releases deploys "$VERSION" new --env "$ENVIRONMENT"

echo "Release $VERSION deployed to $ENVIRONMENT"

Monorepo with multiple Sentry projects:

# Each service gets its own release prefix
sentry-cli releases new "api@$SHA" --project api-backend
sentry-cli releases new "web@$SHA" --project web-frontend

# Upload source maps per project
SENTRY_PROJECT=api-backend sentry-cli sourcemaps upload --release="api@$SHA" ./api/dist
SENTRY_PROJECT=web-frontend sentry-cli sourcemaps upload --release="web@$SHA" ./web/dist

Query release health via API:

# Get release health stats
curl -H "Authorization: Bearer $SENTRY_AUTH_TOKEN" \
  "https://sentry.io/api/0/organizations/$SENTRY_ORG/releases/$VERSION/" \
  | jq '{version: .version, dateCreated: .dateCreated, commitCount: .commitCount, newGroups: .newGroups}'
