What is Cortex?

Cortex 1.22 is on its fourth candidate, with sharded Parquet and years of deprecated flags removed.

Cortex 1.22.0 has been in release candidates since 12 September, reaching rc.3 on 6 October, and GitHub shows no final yet. The candidate adds sharded Parquet conversion and querying, resource-based query eviction that cancels the heaviest query when CPU or heap crosses a threshold, OCI Object Storage as a backend, and an active-series tracker per tenant. It also removes long-deprecated flags and config fields, some of which now stop Cortex from starting if left in place.

What is RStudio?

RStudio opens the 2026.11 train with another NOTICE file update.

RStudio's tagged releases since June have been release-train mechanics: branch syncs, NOTICE-file updates, an internal multipart-parsing rewrite and a Windows 32-bit install fix. The 2026.10.1 patch carried only a branch merge, and the first 2026.11 'Montauk Daisy' tag on November 6 updates third-party notices and the tooling that generates them. The last user-facing changes were in May and June.

Cortex vs RStudio: editorial side-by-side

2.5

Cortex 1.22 is on its fourth candidate, with sharded Parquet and years of deprecated flags removed.

◆ Current state

Cortex 1.22.0 has been in release candidates since 12 September, reaching rc.3 on 6 October, and GitHub shows no final yet. The candidate adds sharded Parquet conversion and querying, resource-based query eviction that cancels the heaviest query when CPU or heap crosses a threshold, OCI Object Storage as a backend, and an active-series tracker per tenant. It also removes long-deprecated flags and config fields, some of which now stop Cortex from starting if left in place.

◆ Where it's heading

The storage arc toward Parquet continues: after 1.21 made Parquet a Store Gateway query mode, 1.22 shards files that exceed column limits. A second arc is protecting shared clusters from heavy tenants, through query eviction, resource-based throttling and concurrent data-byte limits on store gateways. The cleanup is the maturity arc from 1.21 carried further: no-op flags that were tolerated for releases now fail at startup.

◆ Prediction

1.22.0 final should follow rc.3, which added only two fixes. Operators should expect upgrade failures from leftover deprecated flags, and the release notes tell them to grep runtime configs before upgrading.

5.0

RStudio opens the 2026.11 train with another NOTICE file update.

◆ Current state

RStudio's tagged releases since June have been release-train mechanics: branch syncs, NOTICE-file updates, an internal multipart-parsing rewrite and a Windows 32-bit install fix. The 2026.10.1 patch carried only a branch merge, and the first 2026.11 'Montauk Daisy' tag on November 6 updates third-party notices and the tooling that generates them. The last user-facing changes were in May and June.

◆ Where it's heading

The public tag stream shows a steady monthly cadence of named release trains with almost no feature content in the notes. Whatever product work is happening is not visible in these entries, so the feed reads as a maintenance log rather than a roadmap.

◆ Prediction

Expect another 2026.10.x patch or the next named train in November; the entries give no signal about which features, if any, it will carry.
