1. ### [Deprecate legacy Workers KV namespace API routes](https://edgetunnel-b2h.pages.dev/changelog/post/2026-07-15-kv-legacy-namespace-routes-deprecation/)  
[ KV ](https://edgetunnel-b2h.pages.dev/kv/)  
The legacy Workers KV API routes under `/accounts/{account_id}/workers/namespaces/*` are deprecated as of July 15, 2026, and will stop working on October 15, 2026\. Migrate to the documented [Workers KV API](https://edgetunnel-b2h.pages.dev/api/resources/kv/) routes under `/accounts/{account_id}/storage/kv/namespaces/*` before that date.  
The legacy and replacement routes are interchangeable. They accept the same request parameters and return the same response payloads. To migrate, update the URL path from `/workers/namespaces/` to `/storage/kv/namespaces/`.  
#### What you need to do  
Update any integration that calls a route under `/accounts/{account_id}/workers/namespaces/` to use the equivalent route under `/accounts/{account_id}/storage/kv/namespaces/`. The migration is a direct URL path substitution — request parameters and response payloads are identical:

  * `GET` and `POST /accounts/{account_id}/workers/namespaces` → `GET` and `POST /accounts/{account_id}/storage/kv/namespaces`
  * `GET`, `PUT`, and `DELETE /accounts/{account_id}/workers/namespaces/{namespace_id}` → `GET`, `PUT`, and `DELETE /accounts/{account_id}/storage/kv/namespaces/{namespace_id}`
  * `GET /accounts/{account_id}/workers/namespaces/{namespace_id}/keys` → `GET /accounts/{account_id}/storage/kv/namespaces/{namespace_id}/keys`
  * `GET /accounts/{account_id}/workers/namespaces/{namespace_id}/metadata/{key_name}` → `GET /accounts/{account_id}/storage/kv/namespaces/{namespace_id}/metadata/{key_name}`
  * `GET`, `PUT`, and `DELETE /accounts/{account_id}/workers/namespaces/{namespace_id}/values/{key_name}` → `GET`, `PUT`, and `DELETE /accounts/{account_id}/storage/kv/namespaces/{namespace_id}/values/{key_name}`  
For more information about the deprecation timeline, refer to [API deprecations](https://edgetunnel-b2h.pages.dev/fundamentals/api/reference/deprecations/).

1. ### [Billable usage and budget alerts now in product sidebars](https://edgetunnel-b2h.pages.dev/changelog/post/2026-06-04-billable-usage-product-sidebar/)  
[ Cloudflare Fundamentals ](https://edgetunnel-b2h.pages.dev/fundamentals/)[ Workers ](https://edgetunnel-b2h.pages.dev/workers/)[ D1 ](https://edgetunnel-b2h.pages.dev/d1/)[ R2 ](https://edgetunnel-b2h.pages.dev/r2/)[ KV ](https://edgetunnel-b2h.pages.dev/kv/)[ Queues ](https://edgetunnel-b2h.pages.dev/queues/)[ Vectorize ](https://edgetunnel-b2h.pages.dev/vectorize/)[ Durable Objects ](https://edgetunnel-b2h.pages.dev/durable-objects/)[ Containers ](https://edgetunnel-b2h.pages.dev/containers/)  
Pay-as-you-go customers can now view billable usage and create [budget alerts](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-13-billable-usage-dashboard-and-budget-alerts/) directly from the product overview pages for [Workers & Pages](https://edgetunnel-b2h.pages.dev/workers/), [D1](https://edgetunnel-b2h.pages.dev/d1/), [R2](https://edgetunnel-b2h.pages.dev/r2/), [Workers KV](https://edgetunnel-b2h.pages.dev/kv/), [Queues](https://edgetunnel-b2h.pages.dev/queues/), [Vectorize](https://edgetunnel-b2h.pages.dev/vectorize/), [Durable Objects](https://edgetunnel-b2h.pages.dev/durable-objects/), and [Containers](https://edgetunnel-b2h.pages.dev/containers/). A new sidebar widget shows current-period spend and the billing cycle date range, alongside a button to create a budget alert.  
The widget pulls from the same data as the [Billable Usage dashboard](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-13-billable-usage-dashboard-and-budget-alerts/) and aligns to your billing cycle (or the current day on Free plans), so the numbers match your invoice. Enterprise contract accounts are not yet supported.  
![Billable usage widget in the Durable Objects product sidebar showing current-period spend and a breakdown by service](https://edgetunnel-b2h.pages.dev/_astro/2026-06-04-billable-usage-product-sidebar.BUuIokn__ZAx1o6.webp)  
Selecting **Create budget alert** opens the budget alert flow inline so you can set a dollar threshold in the same place you are reviewing usage. Budget alerts apply to your total account-level spend across all products, not just the product page you create them from.  
For more information, refer to the [Usage-based billing documentation](https://edgetunnel-b2h.pages.dev/billing/).

1. ### [Reduced minimum cache TTL for Workers KV to 30 seconds](https://edgetunnel-b2h.pages.dev/changelog/post/2026-01-30-kv-reduced-minimum-cachettl/)  
[ KV ](https://edgetunnel-b2h.pages.dev/kv/)  
The minimum `cacheTtl` parameter for Workers KV has been reduced from 60 seconds to 30 seconds. This change applies to both `get()` and `getWithMetadata()` methods.  
This reduction allows you to maintain more up-to-date cached data and have finer-grained control over cache behavior. Applications requiring faster data refresh rates can now configure cache durations as low as 30 seconds instead of the previous 60-second minimum.  
The `cacheTtl` parameter defines how long a KV result is cached at the global network location it is accessed from:

**JavaScript**  
```js  
// Read with custom cache TTL  
const value = await env.NAMESPACE.get("my-key", {  
  cacheTtl: 30, // Cache for minimum 30 seconds (previously 60)  
});  
// getWithMetadata also supports the reduced cache TTL  
const valueWithMetadata = await env.NAMESPACE.getWithMetadata("my-key", {  
  cacheTtl: 30, // Cache for minimum 30 seconds  
});  
```  
The default cache TTL remains unchanged at 60 seconds. Upgrade to the latest version of Wrangler to be able to use 30 seconds `cacheTtl`.  
This change affects all KV read operations using the binding API. For more information, consult the [Workers KV cache TTL documentation](https://edgetunnel-b2h.pages.dev/kv/api/read-key-value-pairs/#cachettl-parameter).

1. ### [New Workers KV Dashboard UI](https://edgetunnel-b2h.pages.dev/changelog/post/2026-01-20-kv-dash-ui-homepage/)  
[ KV ](https://edgetunnel-b2h.pages.dev/kv/)  
[Workers KV](https://edgetunnel-b2h.pages.dev/kv/) has an updated dashboard UI with new dashboard styling that makes it easier to navigate and see analytics and settings for a KV namespace.  
The new dashboard features a **streamlined homepage** for easy access to your namespaces and key operations, with consistent design with the rest of the dashboard UI updates. It also provides an **improved analytics view**.  
![New KV Dashboard Homepage](https://edgetunnel-b2h.pages.dev/_astro/kv-dash-ui-homepage.BT5hNntj_1OgUmv.webp)  
The updated dashboard is now available for all Workers KV users. Log in to the [Cloudflare Dashboard ↗](https://dash.cloudflare.com/) to start exploring the new interface.

1. ### [Workers KV completes hybrid storage provider rollout for improved performance, fault-tolerance](https://edgetunnel-b2h.pages.dev/changelog/post/2025-08-22-kv-performance-improvements/)  
[ KV ](https://edgetunnel-b2h.pages.dev/kv/)  
Workers KV has completed rolling out performance improvements across all KV namespaces, providing a significant latency reduction on read operations for all KV users. This is due to architectural changes to KV's underlying storage infrastructure, which introduces a new metadata later and substantially improves redundancy.  
![Workers KV latency improvements showing P95 and P99 performance gains in Europe, Asia, Africa and Middle East regions as measured within KV's internal storage gateway worker.](https://edgetunnel-b2h.pages.dev/_astro/kv-hybrid-providers-performance-improvements.D6MBO22S_2ok8qE.webp)  
#### Performance improvements  
The new hybrid architecture delivers substantial latency reductions throughout Europe, Asia, Middle East, Africa regions. Over the past 2 weeks, we have observed the following:

  * **p95 latency**: Reduced from \~150ms to \~50ms (67% decrease)
  * **p99 latency**: Reduced from \~350ms to \~250ms (29% decrease)

1. ### [Read multiple keys from Workers KV with bulk reads](https://edgetunnel-b2h.pages.dev/changelog/post/2025-04-10-kv-bulk-reads/)  
[ KV ](https://edgetunnel-b2h.pages.dev/kv/)  
You can now retrieve up to 100 keys in a single bulk read request made to Workers KV using the binding.  
This makes it easier to request multiple KV pairs within a single Worker invocation. Retrieving many key-value pairs using the bulk read operation is more performant than making individual requests since bulk read operations are not affected by [Workers simultaneous connection limits](https://edgetunnel-b2h.pages.dev/workers/platform/limits/#simultaneous-open-connections).

**JavaScript**  
```js  
// Read single key  
const key = "key-a";  
const value = await env.NAMESPACE.get(key);  
// Read multiple keys  
const keys = ["key-a", "key-b", "key-c", ...] // up to 100 keys  
const values : Map<string, string?> = await env.NAMESPACE.get(keys);  
// Print the value of "key-a" to the console.  
console.log(`The first key is ${values.get("key-a")}.`)  
```  
Consult the [Workers KV Read key-value pairs API](https://edgetunnel-b2h.pages.dev/kv/api/read-key-value-pairs/) for full details on Workers KV's new bulk reads support.

1. ### [Workers KV namespace limits increased to 1000](https://edgetunnel-b2h.pages.dev/changelog/post/2025-01-27-kv-increased-namespaces-limits/)  
[ KV ](https://edgetunnel-b2h.pages.dev/kv/)  
You can now have up to 1000 Workers KV namespaces per account.  
Workers KV namespace limits were increased from 200 to 1000 for all accounts. Higher limits for Workers KV namespaces enable better organization of key-value data, such as by category, tenant, or environment.  
Consult the [Workers KV limits documentation](https://edgetunnel-b2h.pages.dev/kv/platform/limits/) for the rest of the limits. This increased limit is available for both the Free and Paid [Workers plans](https://edgetunnel-b2h.pages.dev/workers/platform/pricing/).
