# Jun 12, 2024 – New frozen rule format and other catalog changes, new PAPI rate limits

* New frozen rule format available for Property Manager users: [v2024-05-31](https://techdocs.akamai.com/property-mgr/reference/deprecated-rule-formats).
* TLS version 1.3 within the Origin Server behavior is now in General Availability. TLS version 1.3 offers significant improvements over earlier versions in both performance and security. See the [Property Manager guide](https://techdocs.akamai.com/property-mgr/docs/origin-server#origin-tls-version) and [PAPI documentation](https://techdocs.akamai.com/property-mgr/reference/ga-origin) for more details.
* New PAPI rate limit to protect PAPI resources from being exhausted by single users. The limit specifies maximum sustainable number of request allowed each minute per account. PAPI also provides a burst limit that specifies how many requests you can make in excess of the imposed rate limit. For details, see [Rate and resource limiting](https://techdocs.akamai.com/property-mgr/reference/rate-and-resource-limiting).
