Expo is running its SDK and EAS release engine at a fast, steady clip.
Expo's feed shows its core release machine turning over: SDK 57 just shipped roughly six weeks after SDK 56's stable release, alongside EAS Workflows automation (iOS device registration), Maestro test insights, and an MCP server now on the free plan. The work spans the SDK, the build/CI cloud (EAS), and testing. Several entries carry only 'Read more' stubs, so feature detail is thin in this feed.
Resend ships a tight, frequent changelog: richer email content and deeper dev-tool reach
Resend is executing the developer-first email playbook with a clean, high-cadence changelog of real features. Recent releases split cleanly between richer email/editor capabilities (Open Graph previews, embedded charts) and embedding Resend into the tools developers already use (Vercel, Claude Code, Auth0, MCP).
Expo's feed shows its core release machine turning over: SDK 57 just shipped roughly six weeks after SDK 56's stable release, alongside EAS Workflows automation (iOS device registration), Maestro test insights, and an MCP server now on the free plan. The work spans the SDK, the build/CI cloud (EAS), and testing. Several entries carry only 'Read more' stubs, so feature detail is thin in this feed.
Two threads: keeping the SDK on a rapid major-version cadence, and deepening EAS as the paid cloud around it (workflows, device registration, testing insights). The MCP server going free signals interest in making Expo projects addressable by AI coding assistants. Expect the SDK cadence to hold and EAS to keep adding CI and testing surface.
Next likely: point releases and migration guidance following SDK 57, and continued EAS Workflows and testing features. Specific features are hard to call from the stub-level content in this feed.
Resend is executing the developer-first email playbook with a clean, high-cadence changelog of real features. Recent releases split cleanly between richer email/editor capabilities (Open Graph previews, embedded charts) and embedding Resend into the tools developers already use (Vercel, Claude Code, Auth0, MCP).
Two arcs are compounding: AI-native composition (mentions in AI chats, AI column mapping on CSV import, chart components) and distribution through integrations (Vercel Marketplace, an official Claude Code plugin, an MCP server, Auth0). Resend is trying to be the email layer that shows up wherever devs and agents already are, not a destination they visit.
Expect more agent- and MCP-facing surface plus marketplace integrations, alongside continued audience tooling building on the CSV import. The cadence is steady incremental execution rather than big directional bets.
