 # Cadence OSS Update: 2025 Lookback

-At the beginning of every year, we share about what happened in the last year. Here’s a look-back to our 2025 improvements, explaining what’s new, and how you can use them. 2025 was one of the most exciting years for the Cadence project and we hope this will only get better in the future.

 Our ambition is to help everyone build complex distributed systems as easily as possible and cover as many overheads in such processes as possible so engineers can get maximum value out of the Cadence project. While there’s still a lot to do to achieve that, this milestone brings us one big step closer.

 ## Adaptive Tasklist Partitioning
 
 ![adaptive-tasklist-partitioning.png](./adaptive-tasklist-partitioning.png)
-Tasklists are queues where workflow tasks are dispatched to user workers. They are hosted in our matching service. By default a single tasklist lives in a single matching host. However, if a tasklist's traffic is large enough, our users used to define how many partitions they would need to have. Upon their changing traffic, they needed to keep adjusting their partitions as well. 
+TaskLists are a FIFO queue used to dispatch tasks to Workers. They are hosted in our matching service. By default a single tasklist lives in a single matching host.

Upon their changing traffic, they needed to keep adjusting their partitions as well. 
 
-As it reads, that’s not the most efficient way to manage thousands of domains. Even with a single domain, this model required Cadence users to learn internal limits about Cadence services and came with unpleasant operational load. Even when this is well-established, manual tuning was almost guaranteed to be suboptimal: you’d either be under utilized or you would accumulate tasks due to not being able to keep up with them.

-Therefore, we made our partitioning logic completely adaptive where \# tasklist partitions automatically grow and shrink based on incoming traffic, providing the perfect scale. In a similar approach, we plan to make as many configurations as possible adaptive soon.

 The best part of this feature is that switching to active-active mode won’t require any migration. All domains will support active-active by default and without breaking existing behavior. While users setting “cluster attributes” while starting their workflows will be able to benefit from active-active processing; leaving these parameters empty will retain the old active-passive behavior.

 Another area we have been focusing on was user education. This is needed for both Cadence basics or new features. For every major new feature, we are now releasing Blogs explaining the impact of the feature, wikis explaining how to use, codelabs going over instructions and videos showing our developer advocate going over the codelab so you won’t get confused or stuck at a certain step.

+Earlier in the year, we released [cadence-web v2](https://cadenceworkflow.io/blog/2025/04/11/2025-04-11-announcing-cadence-web-v4/announcing-cadence-web-v4). It was a complete rewrite from the previous version. We migrated from Vue.js to React, completely redesigned the UI, added multi environment support, and improved the performance significantly.

+With the new changes, extending cadence-web became much simpler as you can see with the changes mentioned below.

+## New History Page

 ## Workflow Actions in Cadence-Web

-Cadence-Web is our web component which provides a user interface to view and manage Cadence workflows. One of the many features we added to cadence-web in 2025 was the ability to directly start or signal workflows from UI. This especially helped with running the initial start command for the cron workflows or internal tools waiting for user inputs.

+## Workflow Diagnostics
+
+![workflow-diagnostics.png](./workflow-diagnostics.png)
+One of the top question categories in our support channels is about diagnosing workflow failures. Most of the issues are repeating patterns that can be easily identified by experienced Cadence users. However, this may not be that obvious to new users.
+
+In 2025, we decided to proactively show issues about workflows in the workflow summary tab where users can click details to learn more. This both reduced the number of support questions we were receiving and also helped our users self-resolve their issues a lot faster.
+
+There’s a codelab and the tutorial video available for this feature if you’d like to try!

We are aware that investing in our community will be the only way scale and build the features that our community asks. Both for users and contributors, we will have more channels and easier ways to collaborate.

 ### Adapting Popular Features
 
-Are you a Cadence user but you wish a specific feature was supported? Are you considering to use Cadence but not having a specific feature is a deal-breaker? Please let us know. Our goal is to have Cadence to handle all the overheads regarding orchestration and distributed systems. Especially if this problem is already solved in somewhere else, we are happy to build and adapt them in Cadence.

 ### Driving Innovation and Modernization
