WhatsApp vs SiYuan: at a glance
What is WhatsApp?
WhatsApp Business is turning Marketing Messages into a full creative-optimization engine.
WhatsApp Business Platform's recent activity is concentrated on the Marketing Messages and MM Lite APIs. Automatic Creative Optimization (ACO) gained several new types — auto promotion tag, product extensions, text formatting, and image background generation — alongside a new endpoint and the 100% rollout of the product_policy field. On the governance side, ACO is now disabled by default at the Business Account level, putting opt-in choice in the merchant's hands. Embedded Signup added new Coexistence countries and webhooks; Cloud API added a new error code (131064) and PARTNER_REMOVED webhook context.
What is SiYuan?
SiYuan's 3.7.0 turns the note-taker into a scriptable, extensible platform
SiYuan is converging its long 3.7.0 dev cycle toward release. The cumulative changelog — repeated across many dev builds — centers on a kernel plugin system, a new command-line interface, configurable secrets and variables, a reworked settings UI, and a large batch of database, editor, and mobile refinements. A breaking change now requires an explicit 'serve' subcommand to run the kernel.

WhatsApp Business is turning Marketing Messages into a full creative-optimization engine.
◆ Current state
WhatsApp Business Platform's recent activity is concentrated on the Marketing Messages and MM Lite APIs. Automatic Creative Optimization (ACO) gained several new types — auto promotion tag, product extensions, text formatting, and image background generation — alongside a new endpoint and the 100% rollout of the product_policy field. On the governance side, ACO is now disabled by default at the Business Account level, putting opt-in choice in the merchant's hands. Embedded Signup added new Coexistence countries and webhooks; Cloud API added a new error code (131064) and PARTNER_REMOVED webhook context.
◆ Where it's heading
WhatsApp is positioning Marketing Messages as a programmatic marketing channel, not a one-off broadcast tool. ACO's expanding catalog (text, images, product mappings) means platforms can hand creative variables to WhatsApp's optimizer rather than ship pre-rendered templates. Account-level default-off and richer conversion metrics suggest Meta is also responding to brand-side concerns about message control and ROI measurement.
◆ Prediction
Expect more ACO levers to ship — likely audience-level optimization and richer attribution back to ads-on-Meta — as WhatsApp leans into being measurable for direct-response advertisers. Embedded Signup country expansion is likely to continue at the current monthly cadence.

SiYuan's 3.7.0 turns the note-taker into a scriptable, extensible platform
◆ Current state
SiYuan is converging its long 3.7.0 dev cycle toward release. The cumulative changelog — repeated across many dev builds — centers on a kernel plugin system, a new command-line interface, configurable secrets and variables, a reworked settings UI, and a large batch of database, editor, and mobile refinements. A breaking change now requires an explicit 'serve' subcommand to run the kernel.
◆ Where it's heading
The headline direction is extensibility and automation: a plugin-capable kernel, CLI access, and secrets/variables move SiYuan from a self-contained app toward something developers can script and integrate. The breaking kernel API changes and the new serve subcommand are the cost of that platform shift. Underneath, steady editor/database hardening and broad localization continue.
◆ Prediction
Expect 3.7.0 to ship from the beta line with the plugin system and CLI as its banner features, followed by an ecosystem period of plugins and integrations building on the new kernel APIs. The repeated dev-build entries don't add direction beyond this.
