cache2k v1.3.2.Alpha Release Notes

Release Date: 2020-08-07 // over 3 years ago

  • 🚀 This is a preview release for evaluation purposes and should not be used in production.

    🆕 New and Noteworthy

    • 🔀 Synchronous execution of expiry listener

    Possible Breakages

    🔀 Cache2kBuilder.addListener will execute an EntryExpiredLister synchronously. In version
    1.2 an expiry listener was always executed asynchronously. This is an potentially incompatible
    🔄 change, in case expiry listeners are used. Review the existing client code and
    👉 make sure that addAsyncListeners is used for an EntryExpiredLister if that is wanted.

    API Changes
