What is Obsidian?
Obsidian's feed has gone quiet: version pointers up top, the bundled CLI the last real move.
The four most recent entries are pointers, not release notes — each says only that the build includes everything up to Obsidian Desktop v1.13.1 through v1.13.4, with no description of what actually changed. The last substantive work visible in this window is from March, when the installer started bundling a dedicated CLI binary instead of invoking the Electron executable, cutting terminal round-trip time and adding shell autocompletion for Obsidian commands. Everything published since is content-free rollup text.
What is Resend?
Resend embeds into Stripe Projects as a provisionable dependency, accelerating platform distribution
Resend is a developer-first email API that has been systematically expanding from transactional email into a full email platform — adding Broadcasts, Segments, template components, and analytics on top of its send API. The September batch shows both directions simultaneously: new API surface for power users (headless webhooks, click link analytics, duplicate broadcast) and enterprise controls (SSO). Notably, the Headless Webhook API explicitly lists the MCP server as a delivery vehicle alongside SDKs and CLI.

◆ Current state
The four most recent entries are pointers, not release notes — each says only that the build includes everything up to Obsidian Desktop v1.13.1 through v1.13.4, with no description of what actually changed. The last substantive work visible in this window is from March, when the installer started bundling a dedicated CLI binary instead of invoking the Electron executable, cutting terminal round-trip time and adding shell autocompletion for Obsidian commands. Everything published since is content-free rollup text.
◆ Where it's heading
Treat the CLI work as the signal and the rollups as noise: a first-class terminal entry point is what lets external tools and scripts drive a vault, which is the difference between a local-first notes app and a substrate other software can build on. The follow-up entries — a macOS path check and a hidden socket dotfile — show the CLI being hardened for real cross-platform use rather than shipped and abandoned. Meanwhile this feed itself has stopped carrying detail, deferring to the desktop release notes it points at.
◆ Prediction
The visible thread is CLI and TUI ergonomics, so continued work on that surface is the safest read; nothing in these entries supports a confident call beyond it. What is genuinely unclear is whether this feed resumes describing releases or stays a pointer to the desktop changelog.

Resend embeds into Stripe Projects as a provisionable dependency, accelerating platform distribution
◆ Current state
Resend is a developer-first email API that has been systematically expanding from transactional email into a full email platform — adding Broadcasts, Segments, template components, and analytics on top of its send API. The September batch shows both directions simultaneously: new API surface for power users (headless webhooks, click link analytics, duplicate broadcast) and enterprise controls (SSO). Notably, the Headless Webhook API explicitly lists the MCP server as a delivery vehicle alongside SDKs and CLI.
◆ Where it's heading
The distribution strategy is sharpening: Stripe Projects provisioning and the earlier Vercel v0 integration put Resend inside platforms where developers are already making infrastructure choices. This embed-into-the-platform approach is a deliberate acquisition channel that bypasses the usual signup funnel. Combined with SSO (unlocking enterprise team adoption) and continued API surface expansion, Resend is moving toward capturing both the individual developer and the team buying motion.
◆ Prediction
More platform integrations following the Stripe and Vercel pattern are the most likely next moves. On the analytics side, click tracking just shipped — open rate and conversion attribution are the logical extensions that would round out the Broadcasts feature set.
