What is Joomla?
Three release lines in parallel, and changelogs that publish checksums instead of changes
Joomla is running three lines at once: 5.4.x maintenance, 6.1.x stable, and a 6.2 alpha. The GitHub release feed is the only signal captured here and it carries no feature detail — every entry repeats the same template of contributor counts, merged-PR counts, download links and SHA-256 checksums, with user-facing notes deferred to an off-site release page. Volume is the only thing that distinguishes them: 5.4.7 merged 43+ pull requests where the 6.1.2 candidates carry one apiece.
What is Customer.io?
Location becomes a trigger, Twilio stops being the only SMS path, and the LLM layer gets a memory
The summer window widens both ends of the automation graph. On the input side, geofences turn physical entry and exit into workflow triggers and date triggers now read attributes off custom objects; on the output side, SMS opens to Sinch, Infobip, and Vonage instead of Twilio alone, and live notifications add a persistent, continuously updating message format on iOS and Android. The LLM side gains a workspace-scoped Knowledge Library that both LLM actions and the Agent can read, replacing per-prompt copy-paste. Channel-based message limits and unsubscribe-preserving profile merges tighten the send-side guardrails underneath all of it.
Joomla vs Customer.io: editorial side-by-side
Joomla
5.0MKT AUTO
Three release lines in parallel, and changelogs that publish checksums instead of changes
◆ Current state
Joomla is running three lines at once: 5.4.x maintenance, 6.1.x stable, and a 6.2 alpha. The GitHub release feed is the only signal captured here and it carries no feature detail — every entry repeats the same template of contributor counts, merged-PR counts, download links and SHA-256 checksums, with user-facing notes deferred to an off-site release page. Volume is the only thing that distinguishes them: 5.4.7 merged 43+ pull requests where the 6.1.2 candidates carry one apiece.
◆ Where it's heading
The pattern is a CMS mid-transition, keeping the 5.x line on a heavy maintenance drip while 6.1 stabilises and 6.2 opens in alpha. Every release links a new migration guide and new developer documentation, which suggests the 5-to-6 upgrade path remains the project's central concern. Where the capability surface is heading isn't determinable from this feed — that information simply isn't published in it.
◆ Prediction
Expect continued parallel maintenance on 5.4.x and 6.1.x with 6.2 progressing through further alphas; the entries give no basis for calling what 6.2 will actually contain.

7.5MKT AUTO
Location becomes a trigger, Twilio stops being the only SMS path, and the LLM layer gets a memory
◆ Current state
The summer window widens both ends of the automation graph. On the input side, geofences turn physical entry and exit into workflow triggers and date triggers now read attributes off custom objects; on the output side, SMS opens to Sinch, Infobip, and Vonage instead of Twilio alone, and live notifications add a persistent, continuously updating message format on iOS and Android. The LLM side gains a workspace-scoped Knowledge Library that both LLM actions and the Agent can read, replacing per-prompt copy-paste. Channel-based message limits and unsubscribe-preserving profile merges tighten the send-side guardrails underneath all of it.
◆ Where it's heading
Customer.io is systematically loosening the assumptions its automation graph was built on: one workspace one app, one SMS vendor, one blunt frequency cap, prompts as the only place LLM context can live. Each release swaps a hardcoded shape for a configurable one, which is what a platform does when its largest accounts have outgrown the original model. The AI work follows the same instinct — not a chatbot bolted on, but retrieval and context turned into workspace-level objects that the rest of the system can reference.
◆ Prediction
Expect the Knowledge Library to spread past LLM actions into more of the Agent's surface, and the per-channel controls to keep filling in — the release notes name WhatsApp and SMS capping outside Twilio as a live gap, which is an odd thing to leave open right after opening SMS to three new vendors.
