v3.9.0

• Updates HTTP callable functions to use structured logging for Node 10+ environments.
• Adds type hints for new Cloud Functions regions asia-northeast3, asia-south1, and asia-southeast2.
• Updates type definition of https.onRequest to allow for promises (async functions).

v3.8.0

• Fixes error when last argument to logger methods is null. (#716)
• Adds eight new available regions:
  • us-west2
  • us-west3
  • us-west4
  • europe-west6
  • asia-northeast2
  • northamerica-northeast1
  • southamerica-east1
  • australia-southeast1
• No longer throw errors for unrecognized regions (deploy will error instead).
• Fixes error where snap.ref in database functions did not work when using the Emulator Suite (#726)

v3.7.0

• Adds functions.logger SDK to enable structured logging in the Node.js 10 runtime. For example:

  const functions = require('firebase-functions');
  
  functions.logger.debug('example log with structured data', {
    uid: user.uid,
    authorized: true,
  });
  

• Adds a special require that mimics Node.js 8 runtime logging in Node.js 10 and later runtimes:

  require('firebase-functions/lib/logger/compat');
  

  In newer runtimes, requiring this will emit text logs with multi-line support and appropriate severity. In the Node.js 8 runtime, the compat module has no effect.

• Fixes https.onRequest type signature to allow Promises for async functions.

v3.6.2

• Pin @types/express version to 4.17.3 to fix type definition issue (Issue #685).
• Firestore onCreate, onUpdate, and onDelete now receive a QueryDocumentSnapshot instead of DocumentSnapshot, which guarantees that data is not undefined (Issue #659).
• Modify return type of DataSnapshot.forEach to boolean | void match firebase-admin SDK.

v3.6.1

• Update TypeScript dependency to v.3.8 to fix build issues (Issue #667)

v3.6.0

• Adds support for europe-west3 region (e.g. functions.region("europe-west3")).
• Adds support for async HTTP functions (Issue #606).

v3.5.0

• Adds support for defining max number of instances for a function. Example:

  functions.runWith({
    maxInstances: 10
  }).https.onRequest(...);
  

  Learn more about max instances in the Google Cloud documentation.

• Fixes TypeScript build error when package-lock.json is present by updating dependencies (Issue #637).

v3.4.0

• Adds support for writing scheduled functions under handler namespace.

v3.3.0

• Add a helper function for the Firebase Emulator suite.

v3.2.0

• Adds support for Test Lab triggered functions with functions.testLab.
• Upgrade lodash dependency to resolve security vulnerability CVE-2019-10744.
