A 4.4.0 tag appears, but the feed carries only its release plumbing
The newest entry is the commit that tagged 4.4.0 — a version.sbt bump plus a local Maven overwrite setting needed for cross-Spark publishing, and it states outright that there are no runtime behaviour changes. The 4.4.0 release notes themselves have not reached this feed, so what the minor version actually contains is not readable here. Behind it sit two patch releases doing targeted correctness work: 3.3.3 on transaction log retention and Delta Sharing cache, 4.3.1 on Delta REST Catalog OAuth and S3A listing, interleaved with near-daily Databricks kernel build tags.
Stretching from subscription infrastructure into hybrid subs+ads revenue tracking, with paywalls getting smarter.
RevenueCat is broadening from subscription-only to subscription-plus-ads with in-app ad revenue tracking now in public beta — apps using AdMob or AppLovin can send ad events through the SDK and see ad and sub revenue side by side. Paywalls have gained meaningful logic depth (Paywall Rules to show/hide components by intro-offer eligibility or custom variables) and the iOS/Android fallback paywall now auto-styles using the app icon's dominant color. Operational tooling has caught up: archived offerings/products/entitlements, OAuth token visibility and revocation, predicted-LTV winners in Experiments.

The project keeps two supported lines stable in parallel while the format work happens elsewhere, and the durable theme across these patches is metadata and log correctness — the failures that silently break time travel and CDF rather than throwing. The 4.4.0 prep notes one thing worth watching: artifacts are now published across Spark 4.0, 4.1 and 4.2 stages, so the cross-Spark support matrix is widening even as the release content stays out of view.
The 4.4.0 release notes should follow this tag and reveal what the minor version carries; until they do the entries support no read on its direction. The unresolved delta-iceberg artifact gap on the 3.3 line still has no follow-up here.
RevenueCat is broadening from subscription-only to subscription-plus-ads with in-app ad revenue tracking now in public beta — apps using AdMob or AppLovin can send ad events through the SDK and see ad and sub revenue side by side.

The product is moving from 'subscription billing infra' to 'mobile monetization platform.' Ad revenue tracking is the headline because it changes who RevenueCat is for — every freemium app with mixed monetization, not just sub-driven apps. Paywall Rules suggest the company is going deeper on the merchandising layer rather than ceding it to MMP-adjacent tools. The Experiments-side LTV predictions and locale-aware paywalls signal continued investment in the optimization story.
Expect the in-app ad revenue beta to GA with deeper SDK support for more ad networks, more sophisticated Paywall Rules conditions (likely user-segment and behavioral triggers), and tighter Experiments + ad-revenue correlation as customers compare hybrid monetization mixes.
