5.0.14 Release Notes

Release Date 18th September 2024

Breaking Changes

Attention: Please read this section carefully.

There are no breaking changes in this release.

Upgrade Instructions

This release is not tightly coupled with Tyk Dashboard v5.0.14, so you do not have to upgrade both together.

Go to the Upgrading Tyk section for detailed upgrade instructions.

Release Highlights

This release fixes some issues related to the way that Tyk performs URL path matching, introducing two new Gateway configuration options to control path matching strictness.

Changelog

Added

  • Implemented Gateway configuration options to set URL path matching strictness

    We have introduced two new options in the http_server_options Gateway configuration that will enforce prefix and/or suffix matching when Tyk performs checks on whether middleware or other logic should be applied to a request:

    • enable_path_prefix_matching ensures that the start of the request path must match the path defined in the API definition
    • enable_path_suffix_matching ensures that the end of the request path must match the path defined in the API definition
    • combining enable_path_prefix_matching and enable_path_suffix_matching will ensure an exact (explicit) match is performed

    These configuration options provide control to avoid unintended matching of paths from Tyk’s default wildcard match. Use of regex special characters when declaring the endpoint path in the API definition will automatically override these settings for that endpoint.

    Tyk recommends that exact matching is employed, but both options default to false to avoid introducing a breaking change for existing users.

Fixed

  • Incorrectly configured regex in policy affected Path-Based Permissions authorization

    Fixed an issue when using granular Path-Based Permissions in access policies and keys that led to authorization incorrectly being granted to endpoints if an invalid regular expression was configured in the key/policy. Also fixed an issue where path-based parameters were not correctly handled by Path-Based Permissions. Now Tyk’s authorization check correctly handles both of these scenarios granting access only to the expected resources.

  • Missing path parameter can direct to the wrong endpoint

    Fixed an issue where a parameterized endpoint URL (e.g. /user/{id}) would be invoked if a request is made that omits the parameter. For example, a request to /user/ will now be interpreted as a request to /user and not to /user/{id}.

  • Improved Gateway Synchronization with MDCB for Policies and APIs

    We have enhanced the Tyk Gateway’s synchronization with MDCB to ensure more reliable loading of policies and APIs. A synchronous initialization process has been implemented to prevent startup failures and reduce the risk of service disruptions caused by asynchronous operations. This update ensures smoother and more consistent syncing of policies and APIs from MDCB.

5.0.13 Release Notes

Release Date 4 July 2024

Release Highlights

Resolved an issue encountered in MDCB environments where changes to custom keys made via the Dashboard were not properly replicated to dataplanes. The issue impacted both key data and associated quotas, in the following versions:

  • 5.0.4 to 5.0.12
  • 5.1.1 and 5.1.2
  • 5.2.0 to 5.2.6
  • 5.3.0 to 5.3.2
Action Required

Customers should clear their edge Redis instances of any potentially affected keys to maintain data consistency and ensure proper synchronization across their environments. Please refer to the item in the fixed section of the changelog for recommended actions.

Changelog

Fixed

  • Resolved an issue where changes to custom keys were not properly replicated to dataplanes

    Resolved a critical issue affecting MDCB environments, where changes to custom keys made via the dashboard were not properly replicated to dataplanes. This affected both the key data and associated quotas. This issue was present in versions:

    • 5.0.4 to 5.0.12
    • 5.1.1 and 5.1.2
    • 5.2.0 to 5.2.6
    • 5.3.0 to 5.3.2

    Action Required

    Customers are advised to clear their edge Redis instances of any keys that might have been affected by this bug to ensure data consistency and proper synchronization across their environments. There are several methods available to address this issue:

    1. Specific Key Deletion via API: To remove individual buggy keys, you can use the following API call:
    curl --location --request DELETE 'http://tyk-gateway:{tyk-hybrid-port}/tyk/keys/my-custom-key' \ --header 'X-Tyk-Authorization: {dashboard-key}'

    Replace {tyk-hybrid-port}, my-custom-key and {dashboard-key} with your specific configuration details. This method is safe and recommended for targeted removals without affecting other keys.

    1. Bulk Key Deletion Using Redis CLI: For environments with numerous affected keys, you might consider using the Redis CLI to remove keys en masse:
    redis-cli --scan --pattern 'apikey-*' | xargs -L 1 redis-cli del
redis-cli --scan --pattern 'quota-*' | xargs -L 1 redis-cli del

    This method can temporarily impact the performance of the Redis server, so it should be executed during a maintenance window or when the impact on production traffic is minimal.

    1. Complete Redis Database Flush: If feasible, flushing the entire Redis database offers a clean slate:
    redis-cli FLUSHALL ASYNC

    Implications Regardless of the chosen method, be aware that quotas will be reset and will need to resynchronize across the system. This may temporarily affect reporting and rate limiting capabilities.

5.0.1 Release Notes

Release Date 25 Apr 2023

Release Highlights

This release primarily focuses on bug fixes. For a comprehensive list of changes, please refer to the detailed changelog below.

Downloads

Changelog

Added
  • Added a new enable_distributed_tracing option to the NewRelic config to enable support for Distributed Tracer
Fixed
  • Fixed panic when JWK method was used for JWT authentication and the token didn’t include kid
  • Fixed an issue where failure to load GoPlugin middleware didn’t prevent the API from proxying traffic to the upstream: now Gateway logs an error when the plugin fails to load (during API creation/update) and responds with HTTP 500 if the API is called; at the moment this is fixed only for file based plugins
  • Fixed MutualTLS issue causing leak of allowed CAs during TLS handshake when there are multiple mTLS APIs
  • Fixed a bug during hot reload of Tyk Gateway where APIs with JSVM plugins stored in filesystem were not reloaded
  • Fixed a bug where the gateway would remove the trailing /at the end of a URL
  • Fixed a bug where nested field-mappings in UDG weren’t working as intended
  • Fixed a bug when using Tyk OAuth 2.0 flow on Tyk Cloud where a request for an Authorization Code would fail with a 404 error
  • Fixed a bug where mTLS negotiation could fail when there are a large number of certificates and CAs; added an option (http_server_options.skip_client_ca_announcement) to use the alternative method for certificate transfer
  • Fixed CVE issue with go.uuid package
  • Fixed a bug where rate limits were not correctly applied when policies are partitioned to separate access rights and rate limits into different scopes

5.0.0 Release Notes

Release Date 28 Mar 2023

Deprecations

  • Tyk Gateway no longer natively supports LetsEncrypt integration. You still can use LetsEncrypt CLI tooling to generate certificates and use them with Tyk.

Release Highlights

Improved OpenAPI support

We have added some great features to the Tyk OAS API definition bringing it closer to parity with our Tyk Classic API and to make it easier to get on board with Tyk using your Open API workflows.

Tyk’s OSS users can now make use of extensive custom middleware options with your OAS APIs, to transform API requests and responses, exposing your upstream services in the way that suits your users and internal API governance rules. We’ve enhanced the Request Validation for Tyk OAS APIs to include parameter validation (path, query, headers, cookie) as well as the body validation that was introduced in Tyk 4.1.

Versioning your Tyk OAS APIs is easier than ever, with the Tyk OSS Gateway now looking after the maintenance of the list of versions associated with the base API for you; we’ve also added a new endpoint on the Tyk API that will return details of the versions for a given API.

We’ve improved support for OAS Mock Responses, with the Tyk OAS API definition now allowing you to register multiple Mock Responses in a single API, providing you with increased testing flexibility.

Of course, we’ve also addressed some bugs and usability issues as part of our ongoing ambition to make Tyk OAS API the best way for you to create and manage your APIs.

Thanks to our community contributors armujahid, JordyBottelier and ls-michal-dabrowski for your PRs that further improve the quality of Tyk OSS Gateway!
