## Memory expiration fields, plus Nova, MCP, and plugin fixes[#](https://supermemory.ai/changelog/2026-03-26-improvements-and-fixes)

New v4 memories can carry an expiration time, a reason for forgetting, and document or event dates, sign-ups with unsupported email domains get a clear rejection, and usage limits account for full request size.

### Improvements

* [New v4 memories can include an expiration time, a reason for forgetting, and document or event dates in the initial request.](https://supermemory.ai/docs/add-memories)

### Fixes

* Sign-up attempts with an unsupported email domain now return a clear rejection instead of a generic server error.
* Usage limits now account for the full size of each request and allow continued processing when organization overage is enabled.
* Nova no longer intermittently shows an Upgrade to Pro prompt on plugin and connection pages for users with an active paid plan.
* MCP connections authenticated with an API key no longer fail with a missing-organization error.
* OpenClaw no longer crashes on startup when the Supermemory store tool is registered.
