v4.0.0 | Refactoring with Breaking Changes

This release bumps the major version because we have done a number of breaking changes. The most notable ones are:

• Package rename core -> api
• Removed GuildController
• Renamed getX(): RestAction to retrieveX(): RestAction
• Added @Nonnull and @Nullable annotations

More can be found in the migration guide.

The plan for version 3.X is to keep updating it with bug fixes until 01/01/2020. We recommend migrating your codebase before then.

v4.BETA.0 | Breaking Changes - Pre-Release

This is the first pre-release of the version 4 changes. I've written a migration guide which should help updating an existing v3 codebase to v4.

We will continue pushing critical bug fixes for v3 for a few months after the final release of v4 but we recommend updating to v4.

v3.8.2 | JDA LTS Release

Important Notice

Recently we have started work on the new major version of JDA
This release signals the end of JDA v3's lifecycle in which we will only be fixing critical issues for the supported timeframe. Once v4 becomes the new stable release we will continue fixing issues with v3 for 6 months to give people with a huge codebase enough time for the conversion. The current expected time for the JDA version 4 release is mid May.

Currently JDA version 4 is in its alpha stadium. This means it receives breaking changes which are not yet supported by 3rd party extensions like lavalink. Once version 4 reaches its beta stadium we will make efforts to help extension developers to adapt to the new ABI provided as soon as possible. We attempt to make a clear separation between what we consider API and internal. We expect extensions to only target the API side of JDA in the future to reduce the possibility of causing incompatibilities.

New features and enhancements will only be coming to JDA 4. This includes new features of Discord as well as overhead reduction such as the changes done to CacheView. One of the major changes coming here is the removal of client-only features such as group channels/messages. We will however continue to support using JDA with AccountType.CLIENT but it will be reduced to features available to bot accounts.

To track what is happening with JDA 4 you can take a look at the milestone: v4

v3.8.1 | Slowmode - Chunking timeout - No more complete() in callbacks

Due to deadlocks in code of less experienced programmers (and even experienced ones) we now prohibit usage of complete() in callbacks of RestAction#queue. This means code similar to the following will no longer work and throw an exception (in the callback).

channel.sendMessage("hello there").queue(message -> {
    message.editMessage("hello world").queue(); // this is still fine
    message.delete().complete(); // exception
});

---

Requesting member chunks can cause a shard to not finish connecting when discord fails to respond. This issue has been known for quite a while and can now be handled properly by JDA thanks to the new setup system introduced in 3.8.0. Now JDA will re-attempt requesting chunks when nothing was received.

---

Discord has released slowmode for text channels in servers, this can now be configured through JDA to allow automation by bots.

v3.8.0 | New shard startup – Easy bulk delete – Cache flags

Due to reports of several issues with shards starting I took the time to completely rewrite all of the startup logic in this release. (#706)
These changes have close to no affect to your codebase apart from one little improvement. I have added GuildReadyEvent which is fired for every single guild on startup before ReadyEvent and ReconnectedEvent are received. This allows guilds to already function without having to wait for everything else to be completed. This means no single guild can keep an entire shard dead. (Users have asked for this).

Because of several caching issues caused by users storing JDA entities such as roles or channels we now changed the cache to use WeakReferences for things such as Role.getGuild().
We highly recommend to just store IDs of entities and a JDA instance (if needed) to then do:

Role role = jda.getRoleById(modRoleId);
...

More on this issue is talked about in the new troubleshooting page.

Deleting messages was really annoying in the past with JDA, until now!
Simply use MessagePaginationAction#takeAsync(...) and MessageChannel#purgeMessages(...).
Example:

MessageChannel channel = event.getChannel();
if (event.getMessage().getContentRaw().equals("--purge")) {
    channel.getIterableHistory().takeAsync(500)
           .thenAccept(channel::purgeMessages);
}

Oh and one more thing... we added a CacheFlag enum to disable some parts of the JDA cache to be more lightweight.

EnumSet<CacheFlag> disabled = EnumSet.of(CacheFlag.GAME, CacheFlag.EMOTE);
JDABuilder builder = new JDABuilder(BOT_TOKEN);
builder.setDisabledCacheFlags(disabled);

I highly recommend only using setDisabledCacheFlags for backwards compatibility.

v3.7.0 | Better Opus Library Support / New Audio Encryption Modes

The opus libraries used for encoding/decoding are now exported to their own dependency at opus-java. This allows for a smaller artifact if no audio encoding has to be performed by JDA (like just sending with lavaplayer).

You can find out how to exclude the dependency and consecutively decrease your classpath size by looking at the Download Section in the README.

We additionally now host a jar without opus natives on jenkins (suffix noOpus).

Discord has added new encryption modes to replace old ones, we now implement all currently supported encryption modes for audio. Additionally we reduced the amount of required allocations for sending audio, which should reduce garbage accumulation and CPU usage respectively.

v3.6.0 | Manager Rewrite, Improved Documentation

In this release we are replacing the old and clunky updatable manager pattern with a new and flashy rest action extension pattern.

Legacy

channel.getManagerUpdatable()
    .getNameField().setValue("testing")
    .getTopicField().setValue("testing channel")
    .update().queue();

New

channel.getManager()
    .setName("testing") // returns ChannelManager
    .setTopic("testing channel") // returns ChannelManager
    .queue();

Documentation

The event documentation got a complete rewrite and should now be a lot cleaner and (hopefully) more understandable than before.

See: javadoc

RestAction Caller Context | Better RequestFuture Continuations

It really is difficult to debug when the stacktraces of RestAction failures don't point to your code...
We got the thing for you! In 3.5.1 we added ContextException which can be used to track caller context for rest actions. What does this mean?

Simply add a failure consumer (see #queue(Consumer, Consumer)) to your restaction queue call and it will create a context exception right there. That exception is then added as a cause to the resulting failure.

RestAction<?> action = channel.sendMessage("Hello, World");
action.queue(null, ContextException.herePrintingTrace());

This will result in a proper exception with traces of the calling code.

If you need to do severe debugging you might want this on every rest action to test.
For this you can simply do the following:

RestAction.setPassContext(true); // enable context by default
RestAction.DEFAULT_FAILURE = Throwable::printStackTrace;

Doing this will result in major performance loss so it is recommended to only go to this extreme when you need to debug errors
