**With this release, `okhttp-tls` no longer depends on Bouncy Castle and doesn't install the
Bouncy Castle security provider.** If you still need it, you can do it yourself:

```
Security.addProvider(BouncyCastleProvider())
```

You will also need to configure this dependency:

constraints.NotEmpty.message = {item} nie może być puste.
constraints.ParametersScriptAssert.message = Wyrażenie skryptowe "{script}" nie jest prawdziwe.
constraints.Range.message = {item} musi być w zakresie od {min} do {max}.
