6.1.0

Rename Jose4jJwtFactory to JOSE4jJwtFactory
Move HelidonJwtFactory and JOSE4jJwtFactory into separate artifacts, dev.blanke.webpush:webpush-jwt-helidon and dev.blanke.webpush:webpush-jwt-jose4j, respectively
- Move implementations into nl.martijndwars.webpush.jwt.{helidon,jose4j} package to avoid split packages
Use ServiceLoader to discover default JwtFactory implementation
- Modularize library by adding module-info.java files to all artifacts
- Add META-INF/services/nl.martijndwars.webpush.jwt.JwtFactory to discover JwtFactory implementations when the module path is not used
Update org.bouncycastle:bcprov-jdk18on to version 1.76 fixing CVE-2023-33201

6.0.0

Target Java 17
No longer separate synchronous and asynchronous PushService implementations
Use java.net.http.HttpClient for default PushService instead of an external dependency
Introduce JwtFactory adapter interface to remove hard dependency on JOSE4j
Separate CLI and library modules

Target Java 8 instead of Java 7.
Added an asynchronous version PushAsyncService of the PushService that performs non-blocking HTTP calls. Uses async-http-client under the hood.

Improvement: Add support for urgency & topic (contributed by jamie@checkin.tech).
Maintenance: Upgrade com.beust:jcommander to 1.78.
Maintenance: Upgrade org.bitbucket.b_c:jose4j to 0.7.0.

Bugfix: Only verify the VAPID key pair if the keys are actually present (fixes #73).
Improvement: Add test configurations for GCM-only to the selenium test suite.

Use aes128gcm as the default encoding (#75).
Remove BouncyCastle JAR from source and let Gradle put together the class path for the CLI.

Support aes128gcm content encoding (#72)
- Use PushService.send(Notification, Encoding) or the analogous sendAsync with Encoding.AES128GCM.
Remove Guava dependency (#69)
