## 2.2.0

**`(feat):`** Add `omitFernHeaders` configuration option. When enabled, Fern platform headers
(X-Fern-Language, X-Fern-SDK-Name, X-Fern-SDK-Version, User-Agent) are omitted
from generated SDK requests.

## 2.1.12

**`(fix):`** Fix WireMock datetime mismatch in wire tests. The mock-utils package generates datetime
query parameter values with milliseconds (e.g., `2022-01-02T00:00:00.000Z`) via
`Date.toISOString()`, but PHP's `DateTimeInterface::RFC3339` format omits fractional
seconds (e.g., `2022-01-02T00:00:00Z`). Since WireMock's `equalTo` is an exact-match,
the stubs never fired. Now strips zero milliseconds from WireMock datetime query
parameter values to match the PHP SDK's serialization format.
