Migration Guide 2.5

Flyway

We upgraded the Flyway dependency from 7.15 to version 8.0. Please refer to the Flyway release notes to see all the changes.

One important breaking change is that Flyway deprecated the Community support for database versions older than 5 years, for example: MySQL 5.7 and PostgreSQL 9.6. Therefore, users using the Flyway community and an unsupported database will have a failure at startup similar to:

Caused by: org.flywaydb.core.internal.license.FlywayEditionUpgradeRequiredException: Flyway Teams Edition or MySQL upgrade required: 
MySQL 5.7 is no longer supported by Flyway Community Edition, but still supported by Flyway Teams Edition.

Hibernate with Panache split packages

To avoid split packages, the following classes was deprecated in 2.1 and are now removed:

• io.quarkus.hibernate.orm.panache.ProjectedFieldName has been removed in favor of io.quarkus.hibernate.orm.panache.common.ProjectedFieldName.

MongoDB with Panache split packages

To avoid split packages, the following classes was deprecated in 2.1 and are now removed:

• io.quarkus.mongodb.panache.MongoEntity has been removed in favor of io.quarkus.mongodb.panache.common.MongoEntity.
• io.quarkus.mongodb.panache.ProjectionFor has been removed in favor of io.quarkus.mongodb.panache.common.ProjectionFor.
• io.quarkus.mongodb.panache.PanacheUpdate has been removed in favor of io.quarkus.mongodb.panache.common.PanacheUpdate.
• io.quarkus.mongodb.panache.reactive.ReactivePanacheUpdate has been removed in favor of io.quarkus.mongodb.panache.common.reactive.ReactivePanacheUpdate.

Vert.x

The quarkus-vertx extension no longer depends on the quarkus-jackson extension. As a result, if your application depends on quarkus-vertx and makes use of the io.vertx.core.json.JsonObject.mapFrom() or the io.vertx.core.json.JsonObject.mapTo() methods then the quarkus-jackson extension should be added (either manually or as a transient dependency) to the project dependencies.
