What is Countly?

Countly 25.03.58 tightens API tokens, sessions and login lockouts in one security patch.

Countly 25.03.58 is a security-heavy patch for the 25.03 line. App-restricted tokens must now declare their permissions, password changes and member lockouts revoke tokens, single-use tokens and reset links work once even under concurrency, and login failures count per account regardless of username casing. It also tightens access to dashboards, dbviewer and exports, and fixes file migration, remote-config targeting and star-rating widgets.

What is Delta Lake?

Delta Lake's public stream is release mechanics; Kernel builds now carry a 4.5.0 label.

Recent Delta Lake activity is mostly release mechanics: 4.4.0 and 4.4.1 tags, a stream of Databricks runtime kernel builds, and patch releases. The newest build is labelled Delta Kernel 4.5.0, the first sign of the next minor line. The substantive user-facing work sits in patches such as the 3.3.3 fix for log cleanup deleting files still needed for time travel.

ANALYTICS
5.0

Countly 25.03.58 tightens API tokens, sessions and login lockouts in one security patch.

◆ Current state

Countly 25.03.58 is a security-heavy patch for the 25.03 line. App-restricted tokens must now declare their permissions, password changes and member lockouts revoke tokens, single-use tokens and reset links work once even under concurrency, and login failures count per account regardless of username casing. It also tightens access to dashboards, dbviewer and exports, and fixes file migration, remote-config targeting and star-rating widgets.

◆ Where it's heading

The 25.03 LTS line keeps absorbing security work at a fast clip: an upstream Node CVE, certificate distrust, and now a sweep of Countly's own token and permission model. Feature work stays in enterprise licensing and journeys, while LTS releases mostly harden what exists.

◆ Prediction

Expect a matching 24.05 backport of the token and permission fixes. Token owners may also need migration guidance, since existing app-restricted tokens without permissions are now limited to their owner's rights.

Delta Lake
ANALYTICS
5.0

Delta Lake's public stream is release mechanics; Kernel builds now carry a 4.5.0 label.

◆ Current state

Recent Delta Lake activity is mostly release mechanics: 4.4.0 and 4.4.1 tags, a stream of Databricks runtime kernel builds, and patch releases. The newest build is labelled Delta Kernel 4.5.0, the first sign of the next minor line. The substantive user-facing work sits in patches such as the 3.3.3 fix for log cleanup deleting files still needed for time travel.

◆ Where it's heading

The project keeps 3.x and 4.x alive and spends its public changelog on correctness and catalog integration rather than new table features. Kernel builds tagged for Databricks runtime suggest Kernel development is paced by Databricks' own release train, with the open-source releases following.

◆ Prediction

A 4.5.0 open-source release is the likely next notable entry given the kernel version label, but the entries don't say what it will contain.
