Val Town Code SearchReturn to Val Town

83We didn't. We left them where they are, and proxy to them.
84
85Writing a proxy in Val Town (or any functions platform with the ['fetch handler' interface](https://blog.val.town/blog/the-api-we-forgot-to-name/)) is a delight:
86
87```ts

82    // if we wanted to create a /lastUpdatedAt route,
83    // which would let us pass a val town bearer token, we could do that here
84    // gives us 10k API requests per minute instead of 1k
85    // and would work with private projects

8Today, we’re unifying our two primitives — *vals* and *projects* — into a single primitive: the **val**, with the best features of both.
9
10Historically, vals have been simple and lightweight, but limited to a single file. This upgrade will preserve the elegant spirit of our platform while supporting more complex code and collaborative workflows. This upgrade will help you create bigger things on Val Town – APIs, internal tools, fullstack apps, blogs ([like this one](https://www.val.town/x/valdottown/blog)), and much more – without sacrificing the simplicity you've always loved about vals.
11
12*Legacy vals* will temporarily become *projects* during this migration. Post-migration, the concept of *projects* will disappear entirely — leaving only upgraded *vals*. In short: *legacy vals* → *projects* → *vals*.
16For most users, no upgrade action is required. We’ll auto-migrate your vals next week. All existing HTTP endpoints, crons, email handlers, and custom domains will be preserved.
17
18For those with mission-critical vals or who use our API to edit or create vals, you can start upgrading your legacy vals today and integrating with our updated API.
19
20- **April 23, 2025** – Announcement of changes & API deprecations.
21- **April 30, 2025** – All remaining *legacy vals* auto-upgraded. Deprecated API routes become read-only.
22- **May 1, 2025** – The term *projects* will no longer exist — everything will simply be a *val*.
23
35[See more details in our docs.](https://docs.val.town/upgrading/legacy-vals)
36
37## API Changes
38
39Today, we're introducing the following API routes:
40
41```bash
73```
74
75View our [updated API reference here](https://docs.val.town/openapi).
76
77All `v1/vals` API routes become read-only on **April 30, 2025**. If you rely on *writing* to those routes, please upgrade to our new `v2/vals` API. All deprecated API routes will continue serving historical legacy val data.
78
79### SDK changes
85
861. Upgrade your mission-critical vals early.
872. Update your Val Town API & SDK usage to `/v2` routes.
883. All remaining legacy vals migrate on **April 30, 2025**.
894. Migration completes on **May 1, 2025**.
