What is Grafana Loki?
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.
What is Marker.io?
Marker.io stops waiting for bug reports and starts scanning sites for accessibility issues.
Marker.io began as a widget for reporting website bugs and spent the past year adding AI to every step: translation, rewriting, title generation and an MCP server that lets coding agents fix issues from a Marker URL. In late October it launched Website Monitoring, which scans chosen pages on a schedule with 90 WCAG 2.2 AA accessibility checks and turns failures into issues.

Grafana Loki
6.3ANALYTICS
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
◆ Current state
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.
◆ Where it's heading
Each candidate trims a bit more legacy surface, so 4.0 is a cleanup major that pushes installs onto TSDB and the microservices or single-binary layouts. The Operator had prepared this path since 0.11 and 0.12.
◆ Prediction
Expect a few more RCs with small breaking changes, then 4.0.0 GA and an Operator release that drops the removed schemas.
Marker.io
3.8ANALYTICS
Marker.io stops waiting for bug reports and starts scanning sites for accessibility issues.
◆ Current state
Marker.io began as a widget for reporting website bugs and spent the past year adding AI to every step: translation, rewriting, title generation and an MCP server that lets coding agents fix issues from a Marker URL. In late October it launched Website Monitoring, which scans chosen pages on a schedule with 90 WCAG 2.2 AA accessibility checks and turns failures into issues.
◆ Where it's heading
The product is moving from collecting problems people report to finding problems on its own, and then handing them to coding agents through MCP. Accessibility is the first monitoring check, and the release title says it is only the start. Workflow statuses and analytics fill in the team side.
◆ Prediction
Expect more monitoring checks beyond accessibility, since the release frames accessibility as the first. How monitoring is priced is not clear from the entries.
