AcyMailing
AcyMailing keeps a steady maintenance cadence with a fresh SQL-injection patch
A side-by-side editorial comparison of CartStack and OneSignal — release velocity, themes, recent moves, and the top alternatives to consider.
A long-quiet cart-recovery tool resurfaces with a 5.0 experience refresh.
CartStack is a cart- and browse-abandonment recovery tool. Its changelog is sparse, spanning several years with long gaps, and the one recent entry is CartStack 5.0 — described as a full experience overhaul where 'everything is new' but the underlying recovery engine is unchanged. The older history shows incremental email and reporting features: webhooks, pre-send email validation, one-click unsubscribe, aggregate reporting.
OneSignal's feed is channel-marketing content, with RCS as the recurring drumbeat
The entries in this feed are marketing and thought-leadership posts, not release notes — nothing here documents a shipped change to OneSignal itself. The consistent editorial thread is a push toward RCS as an upgrade over plain SMS, wrapped in broader multi-channel and lifecycle-messaging themes. Read as content strategy, OneSignal is positioning around channel breadth and user migration: email-to-push, SMS-to-RCS, and reaching app-less users over text.

5.0 reads as a UI and platform refresh rather than a capability change — the company is explicit that the results-delivering engine stays the same. After a quiet stretch, this could signal renewed investment, but the sparse release history makes it hard to read a sustained trajectory from these entries alone.
Whether 5.0 marks a return to steady shipping or a one-off refresh is unclear from the changelog; the multi-year gaps between releases make cadence hard to predict.

If blog cadence tracks product priorities, OneSignal keeps leaning into RCS and cross-channel orchestration as its differentiation, with the pitch framed around retention and lifetime value rather than raw reach. The recurring 'move your most engaged users to a better channel' framing points at lifecycle depth over acquisition. What the feed does not show is any concrete product mechanics, so this direction is inferred from marketing emphasis, not shipped features.
Because this feed carries marketing content and no release notes, a product prediction isn't well-grounded; the safe read is more RCS- and multi-channel-focused content, with any actual RCS feature launch unconfirmed here.
