# Togo v0.2.14 — Changes to event definition terminology and email enforcement

Released November 3, 2026 · Ingestion
Permalink: https://www.togohq.ai/changelog/v0.2.14

## Breaking

- The governance wire's `declared` and `contractSha256` are now `defined` and `definitionSha256`. This affects how controls are read by the CLI and SDKs.

## Improved

- Session IDs that resemble emails are no longer rejected at the edge. Instead, they are flagged in test events for diagnostics.

## Migration

Update code to use 'defined' instead of 'declared' and 'definitionSha256' instead of 'contractSha256'.

Before:

```ts
declared, contractSha256
```

After:

```ts
defined, definitionSha256
```

The old form stops working in v0.2.14.
