Feels like a good time to let everyone know my current active project and what to upcoming releases to expect. Currently CB Activity is the active project. This means that's the project being focused on outside of bug fixes since we will of course interrupt any active project to fix bugs. In addition to this Joomla 4 compatibility testing and fixing is still being done as issues are discovered. We've addressed the majority of Joomla 4 issues already in latest build release of CB. More details about CB Activity development below.
CB Activity 6.0.0 will be a significant rewrite. It will only migrate from CB Activity 5.0.0 so please be sure your install is up to date. CB Activity is undergoing massive performance improvements and structure changes to move it towards scaleability. CB Activity 6.0.0 has been performance tested against 5 MILLION unique activity entries and clocks in at a blazing fast 2ms (milliseconds!). This means you'll be able to put your trust into CB Activity to deliver high performance activity streams looong into the future for your site!
All the database queries have been touched. All costly _users and _comprofiler table joins have been removed. This means posts belonging to deleted user, banned users, or blocked users are allowed. By default deleted user posts will also be deleted, banned users posts will stop linking to their profile, and blocked users posts will become unpublished. This significantly helps optimize the query away from doing these costly joins. Next all ordering has been changed to no longer be date based. This means all posts will display in the order they were created. So you may notice some posts out of order, but that's normal. This leads us into cursor based pagination. Currently CB Activity is using offset pagination. This basically fails after 30+ pages with a database of 1 million activity. This is due to how the database has to go through previous pages to reach the desired page and gets slower with each page. The cursor based pagination completely eliminates this. That means whether page 1 or page 100 you get the same performance and makes infinite scroll actually pleasant to use.
Global posts have been removed. These were always out of context and were used as a strange means of making site wide announcements that showed on every stream out of context. If you need global posts I suggest instead making a custom stream for those global posts (e.g. set its asset to "global") then add that streams asset to any stream you want those global posts shown on.
Pinned posts have been removed. This pulled a post out of its database order and pushed it to the top. This is awful on the query optimization and constantly caused expensive filesorts. There are no plans for an alternative or workaround for pinned post removal. It's officially a deprecated and removed feature.
First page paging limit has been removed. This allowed you supply a different limit for the first page of a stream (e.g. first page shows 5 for first page then 10 for next page). This was removed due to the difficulty of detecting first page during cursor based paging and hurt query caching.
Stored streams are coming. A stored stream is a preconfigured stream object that can be reused. Currently streams are dynamically generated, stored in user session, and rebuilt on each page load. This is slow, prevents linking to activity, and prevents cross-stream rebuilding (e.g. a post from Stream A shown on Stream B will display based off Stream B parameters instead of Stream A parameters). This will bring significantly improved support for UNLIMITED streams.
Likes, Follows, and Notifications "streams" will be replaced with static APIs. It never made sense for likes/follows to be their own streams. These will be changed to a generic set of FAST APIs for liking/following things. Notifications never made sense to allow different notification streams. Notifications will be reduced down purely to be profile notifications (as they are by default) and remove support for making custom notification streams.
A LOT of new features are planned that would just turn this into an even longer wall of text so I highly recommend checking out our forge below to see what's coming.

There isn't a timeline for this at this time, but it's currently under development as we speak and on its way. The primary goal of this release is optimization more than anything, but some great new things will absolutely be coming!
