What is NGINX?
nginx patched HTTP/3 twice in a month and is trimming old platform code on mainline.
nginx runs a 1.31 mainline and a 1.30 stable line. After 1.31.5 added a native control API, a JSON module and predicate locations in September, the following releases were mostly security: 1.31.6 and 1.30.5 fixed an HTTP/3 buffer overflow (CVE-2026-90439), then 1.31.7 and 1.30.6 fixed five more CVEs including HTTP/3 request body injection. 1.31.8 on October 21 removed the Win32 iocp event module and fixed further HTTP/3 issues.
What is SavvyCal?
SavvyCal lets Claude or ChatGPT book and move meetings through an MCP server on every plan.
SavvyCal ships about once a month, and its latest release is the largest in a year: an MCP server on every plan that lets AI assistants find times, book or move meetings, block time and run polls. Earlier releases were contained refinements such as duplicating workflows, locking links before an event, per-event buffers and multi-language booking pages.
NGINX vs SavvyCal: editorial side-by-side
NGINX
5.0INFRA · APIS
nginx patched HTTP/3 twice in a month and is trimming old platform code on mainline.
◆ Current state
nginx runs a 1.31 mainline and a 1.30 stable line. After 1.31.5 added a native control API, a JSON module and predicate locations in September, the following releases were mostly security: 1.31.6 and 1.30.5 fixed an HTTP/3 buffer overflow (CVE-2026-90439), then 1.31.7 and 1.30.6 fixed five more CVEs including HTTP/3 request body injection. 1.31.8 on October 21 removed the Win32 iocp event module and fixed further HTTP/3 issues.
◆ Where it's heading
HTTP/3 has needed fixes in each of the last three mainline releases, two of them CVEs. Mainline is adding features and removing legacy code at the same time, while stable gets the CVE backports.
◆ Prediction
More HTTP/3 fixes on both lines are likely; on mainline, follow-up work on the control API and JSON module is the next feature thread to watch.
SavvyCal
2.5INFRA · APIS
SavvyCal lets Claude or ChatGPT book and move meetings through an MCP server on every plan.
◆ Current state
SavvyCal ships about once a month, and its latest release is the largest in a year: an MCP server on every plan that lets AI assistants find times, book or move meetings, block time and run polls. Earlier releases were contained refinements such as duplicating workflows, locking links before an event, per-event buffers and multi-language booking pages.
◆ Where it's heading
For most of the year SavvyCal has added control for hosts and assistants who schedule for others. The MCP server extends that to software assistants: the same booking and rescheduling actions now work from a chat. That puts SavvyCal's scheduling logic inside other tools instead of only on its booking pages.
◆ Prediction
Expect follow-ups that widen what the MCP server can do, such as more scheduling actions. The single release gives little else to predict from.
