What is SigNoz?
SigNoz sets November 11 to drop v1 alert rules and ships Telegram alerts and GCP logs.
SigNoz ships a weekly changelog led by API deprecation notices. The October 22 edition sets November 11 for removing the v1 alert rule schema and endpoints, with stored rules rewritten to v2alpha1 on upgrade, and confirms the v1 alert-history endpoints are gone. It also moves saved views into the Explorer sidebar, rebuilds Notification Channels on the v2 API with richer Slack formatting, and adds Telegram alerts and GCP log collection.
What is WireMock?
WireMock 4.0 is on its 41st beta, mostly fixes and dependency bumps after a big API rework.
WireMock is the standard Java tool for mocking HTTP APIs, and its 4.0 line is still in beta. The latest betas are dominated by Dependabot bumps and targeted fixes such as honoring the HTTPS trust-store type and making resetAll() clear message stubs. Beta.40 carried one breaking change: journal stores now enforce maxEntries themselves.

SigNoz
5.0INFRA · APIS
SigNoz sets November 11 to drop v1 alert rules and ships Telegram alerts and GCP logs.
◆ Current state
SigNoz ships a weekly changelog led by API deprecation notices. The October 22 edition sets November 11 for removing the v1 alert rule schema and endpoints, with stored rules rewritten to v2alpha1 on upgrade, and confirms the v1 alert-history endpoints are gone. It also moves saved views into the Explorer sidebar, rebuilds Notification Channels on the v2 API with richer Slack formatting, and adds Telegram alerts and GCP log collection.
◆ Where it's heading
SigNoz is retiring its v1 alerting API in stages, history first and rules next, while widening where alerts go (Jira, incident.io, now Telegram) and what it ingests. The August plugin for AI coding agents remains its main directional bet; recent weeks are platform cleanup around it.
◆ Prediction
Expect weekly reminders until November 11, then a release that removes v1 rules. Further alert channels and cloud-integration log sources are the likely feature follow-ups.
WireMock
5.0INFRA · APIS
WireMock 4.0 is on its 41st beta, mostly fixes and dependency bumps after a big API rework.
◆ Current state
WireMock is the standard Java tool for mocking HTTP APIs, and its 4.0 line is still in beta. The latest betas are dominated by Dependabot bumps and targeted fixes such as honoring the HTTPS trust-store type and making resetAll() clear message stubs. Beta.40 carried one breaking change: journal stores now enforce maxEntries themselves.
◆ Where it's heading
The structural work landed in June. Beta.35 introduced a unified Entity body abstraction across stubs, webhooks and messages, and added breaking-change reporting on the published API. Since then the releases have been stabilization, with message channels getting most of the attention. The project is converging, not expanding.
◆ Prediction
Expect more betas that fix message channels and the journal, with the breaking-change reports gating a 4.0 release candidate. The entries give no date for GA.
