What is Calibre?

Calibre is tying every performance number back to the deploy that caused it.

The August release brings deployments into Real User Monitoring: deploy markers run along the bottom of charts, hovering one reveals the commit, author, and time, and clicking through opens the commit in source control, with each deployment compared against the previous. The same day, Synthetic metrics moved from one page at a time to median aggregates across all pages, segmented by test profile, deployment, and page — so a regression can be identified as site-wide or isolated. Before that: automatic measurement of soft navigations in single-page apps, a site-scan crawler that discovers and maintains the monitored page list on its own, self-service SAML SSO with SCIM on the Team plan, and an organisation-wide audit log that exports as NDJSON or streams to a SIEM over signed webhooks.

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.

Calibre is tying every performance number back to the deploy that caused it.

◆ Current state

The August release brings deployments into Real User Monitoring: deploy markers run along the bottom of charts, hovering one reveals the commit, author, and time, and clicking through opens the commit in source control, with each deployment compared against the previous. The same day, Synthetic metrics moved from one page at a time to median aggregates across all pages, segmented by test profile, deployment, and page — so a regression can be identified as site-wide or isolated. Before that: automatic measurement of soft navigations in single-page apps, a site-scan crawler that discovers and maintains the monitored page list on its own, self-service SAML SSO with SCIM on the Team plan, and an organisation-wide audit log that exports as NDJSON or streams to a SIEM over signed webhooks.

◆ Where it's heading

Calibre is closing the loop between a metric moving and someone knowing why. Deployment attribution supplies the cause, the all-pages segmentation supplies the scope, and soft-navigation measurement fills the blind spot that made SPA numbers untrustworthy in the first place. Running alongside that is a distinctly enterprise track — SSO, SCIM, and an audit log with SIEM streaming are procurement requirements, and putting SAML on the Team plan rather than reserving it for Company is a deliberate move down-market with them.

◆ Prediction

Expect deployment attribution to grow into alerting — a regression tied to a specific commit is the natural trigger for a notification, and the pieces are now all in place. How far the site-scan crawler is meant to replace manual page management is not yet clear from these entries.

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.
