What is Glances?
Glances 4.5.9 closes out the 4.x line as a 5.0 beta opens for testing.
Glances 4.5.9 replaces the python-jose library, which carried a CVE, with PyJWT and updates every dependency. The notes say it is the last 4.x release and point users to a Glances 5.0.0 beta on Test PyPI and a dev Docker image. Most 4.5 releases this year were security and correctness fixes.
What is updown.io?
updown.io sends domain-expiry alerts to every channel and moves French SMS alerts to a UK number.
On 8 November updown.io moved SMS alerts sent from its French number to a UK number after the French regulator reserved mobile numbers for person-to-person messages. The same update routes domain expiration alerts through every notification channel with a new webhook event, adds dashboard warnings for malformed HTTP/2 headers, errors after a 2xx and charset mismatches, and exposes certificate details in the API. September brought a detailed check page with multi-year heatmaps and SLA history.

Glances
5.0ANALYTICS
Glances 4.5.9 closes out the 4.x line as a 5.0 beta opens for testing.
◆ Current state
Glances 4.5.9 replaces the python-jose library, which carried a CVE, with PyJWT and updates every dependency. The notes say it is the last 4.x release and point users to a Glances 5.0.0 beta on Test PyPI and a dev Docker image. Most 4.5 releases this year were security and correctness fixes.
◆ Where it's heading
After a year of CVE patches and alert correctness work on 4.5, the project is ending the 4.x line and moving to 5.0. The feed does not yet describe what changes in 5.0.
◆ Prediction
Expect further 5.0 betas and then a 5.0.0 release; whether it changes the plugin model, web UI or API is not visible in these entries.
updown.io
2.5ANALYTICS
updown.io sends domain-expiry alerts to every channel and moves French SMS alerts to a UK number.
◆ Current state
On 8 November updown.io moved SMS alerts sent from its French number to a UK number after the French regulator reserved mobile numbers for person-to-person messages. The same update routes domain expiration alerts through every notification channel with a new webhook event, adds dashboard warnings for malformed HTTP/2 headers, errors after a 2xx and charset mismatches, and exposes certificate details in the API. September brought a detailed check page with multi-year heatmaps and SLA history.
◆ Where it's heading
updown.io keeps widening what a single check reports, from heatmaps and SLA history to certificate and domain data, while staying a small, steady shipper. Alerts now reach the channels teams already use rather than email alone.
◆ Prediction
Expect more domain and certificate signals exposed through the API and webhooks, extending the domain-expiration event added here.
