  • Bumped the version to 1.0.
  • Removed the "preview" notices for Google Cloud Functions since the Ruby runtime is now GA.

v0.11.0 / 2021-06-28

  • UPDATED: Update CloudEvents dependency to 0.5 to get fixes for JSON formatting cases
  • FIXED: Updated Pub/Sub and Firebase event conversion logic to better align to Eventarc

v0.10.0 / 2021-06-01

  • ADDED: Support raw pubsub events sent by the pubsub emulator
  • FIXED: Set proper response content-type charset when a function returns a string (plain text) or hash (JSON)
  • FIXED: Properly handle conversion of non-ascii characters in legacy event strings

v0.9.0 / 2021-03-18

  • BREAKING CHANGE: Servers are configured as single-threaded in production by default, matching the current behavior of Google Cloud Functions.
  • FIXED: Fixed conversion of Firebase events to CloudEvents to conform to the specs used by Cloud Functions and Cloud Run.
  • FIXED: Fixed an error when reading a global set to a Minitest::Mock. This will make it easier to write tests that use mocks for global resources.

v0.8.0 / 2021-03-02

  • ADDED: Support for lazily-initialized globals

v0.7.1 / 2021-01-26

  • DOCS: Fixed several errors in the writing-functions doc samples
  • DOCS: Updated documentation to note public release of GCF support

v0.7.0 / 2020-09-25

  • Now requires Ruby 2.5 or later.
  • BREAKING CHANGE: Renamed "context" hash to "globals" and made it read-only for normal functions.
  • BREAKING CHANGE: Server config is no longer passed to startup blocks.
  • ADDED: Provided a "logger" convenience method in the context object.
  • ADDED: Globals can be set from startup blocks, which is useful for initializing shared resources.
  • ADDED: Support for testing startup tasks in the Testing module.
  • ADDED: Support for controlling logging in the Testing module.
  • FIXED: Fixed crash introduced in 0.6.0 when a block didn't declare an expected argument.
  • FIXED: Better support for running concurrent tests.
  • DOCS: Expanded documentation on initialization, execution context, and shared resources.
  • DEPRECATED: The functions-framework executable is deprecated. Use functions-framework-ruby instead.

v0.6.0 / 2020-09-17

  • ADDED: You can use the --version flag to print the framework version
  • ADDED: You can use the --verify flag to verify that a given function is defined
  • ADDED: You can now define blocks that are executed at server startup

v0.5.2 / 2020-09-06

  • FIXED: Use global $stderr rather than STDERR for logger
  • DOCS: Fix instructions for deployment to Google Cloud Functions

v0.5.1 / 2020-07-20

  • Updated some documentation links. No functional changes.

v0.5.0 / 2020-07-09

  • Removed embedded CloudEvents classes and added the official CloudEvents SDK as a dependency. A FunctionsFramework::CloudEvents alias provides backward compatibility.

v0.4.1 / 2020-07-08

  • Fixed unsupported signal error on Windows.
  • Fixed several edge case errors in legacy event conversion.
  • Generated Content-Type headers now properly quote param values if needed.
  • Minor documentation updates.

v0.4.0 / 2020-06-29

  • Dropped the legacy and largely unsupported :event function type. All event functions should be of type :cloud_event.
  • Define the object context for function execution, and include an extensible context helper.
  • Support for CloudEvents with specversion 0.3.
  • CloudEvents now correct percent-encodes/decodes binary headers.
  • CloudEvents now includes more robust RFC 2045 parsing of the Content-Type header.
  • The CloudEventsError class now properly subclasses StandardError instead of RuntimeError.
  • Removed redundant _string accessors from event classes since raw forms are already available via [].
  • A variety of corrections to event-related class documentation.

v0.3.1 / 2020-06-27

  • Fixed crash when using "return" directly in a function block.
  • Added a more flexible request generation helper in the testing module.
  • Fixed several typos in the documentation.

v0.3.0 / 2020-06-26

  • Updated the CloudEvent data format for converted pubsub events to conform to Cloud Run's conversion.

v0.2.1 / 2020-06-25

  • The --signature-type check recognizes the legacy event type for :cloud_event functions.

v0.2.0 / 2020-06-24

Significant changes:

  • Converts legacy GCF events and passes them to functions as CloudEvents.
  • The executable is now named functions-framework-ruby to avoid collisions with functions frameworks for other languages.
  • Deprecated the event function type. Use cloud_event.
  • The CloudEvents implementation is now fully-featured and can encode as well as decode events.
  • Wrote an expanded set of getting-started documentation.

Minor changes:

  • Testing.load_temporary now caches loaded functions so they don't have to be reloaded for subsequent tests.
  • The executable recognizes the --signature-type flag, and verifies that the type is correct.
  • Error reporting is expanded and improved.
  • Fixed a crash when a batch CloudEvent was received. (These are still not supported, and now result in a 400.)
  • Renamed a few undocumented environment variables, and added support for a logging level environment variable. All CLI flags now have associated environment variables.
  • Several fixes to the example code, and added a new Sinatra example.

v0.1.1 / 2020-02-27

  • Server returns 404 when receiving a /favicon.ico or /robots.txt request.
