What is Ably?

Ably clears its iOS SDK of a 'tracking' privacy label while pitching realtime to AI agents.

Ably is a realtime messaging platform that is repositioning its pub/sub infrastructure as transport for AI agent output, alongside LiveObjects shared state. Recent releases are SDK hardening: faster liveness detection, LiveObjects reaching stable across platforms, simpler channel rules and permissions, and now a corrected iOS privacy manifest.

What is Cronicle?

Cronicle keeps patching vulnerable dependencies, two more bumps in three days.

Cronicle 0.9.138 and 0.9.139 each bump one dependency for upstream vulnerability fixes: sanitize-html, then pixl-mail for nodemailer. That makes six dependency-driven releases in under two months. The last functional changes were privilege filtering on active jobs and HTTP status retention in August and September.

Ably vs Cronicle: editorial side-by-side

A
Ably
INFRA · APIS
5.0

Ably clears its iOS SDK of a 'tracking' privacy label while pitching realtime to AI agents.

◆ Current state

Ably is a realtime messaging platform that is repositioning its pub/sub infrastructure as transport for AI agent output, alongside LiveObjects shared state. Recent releases are SDK hardening: faster liveness detection, LiveObjects reaching stable across platforms, simpler channel rules and permissions, and now a corrected iOS privacy manifest.

◆ Where it's heading

The product is running two tracks: AI Transport for streaming and steering agent output, and steady maturation of the core SDKs and the config-as-code surface. The core work removes friction for app developers, such as App Store privacy labels, Terraform and permission rules, so the platform is easier to adopt.

◆ Prediction

Expect AI Transport to move toward a 1.0 SDK, and LiveObjects stable releases for the remaining platform SDKs.

C
Cronicle
INFRA · APIS
5.0

Cronicle keeps patching vulnerable dependencies, two more bumps in three days.

◆ Current state

Cronicle 0.9.138 and 0.9.139 each bump one dependency for upstream vulnerability fixes: sanitize-html, then pixl-mail for nodemailer. That makes six dependency-driven releases in under two months. The last functional changes were privilege filtering on active jobs and HTTP status retention in August and September.

◆ Where it's heading

The 0.9.x line is in maintenance: security-driven dependency bumps and occasional correctness fixes, released as soon as an upstream advisory lands. Nothing in the entries hints at new scheduling features.

◆ Prediction

Expect more single-dependency 0.9.x releases following upstream advisories, especially for nodemailer and other mail and HTML dependencies.
