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.
What is Skipper?
Skipper now serves zone-filtered routes only when its own ingress is balanced across zones.
Skipper, Zalando's HTTP router and Kubernetes ingress, tags a release for nearly every merge, so most entries are dependency bumps. The substantive ones this autumn are about zone-aware routing: v0.28.56 made routesrv recompress only zones whose routes changed, and v0.28.60 on November 2 serves zone-filtered routes only when skipper-ingress is balanced across zones, falling back to the global table otherwise.

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.
Skipper
5.0INFRA · APIS
Skipper now serves zone-filtered routes only when its own ingress is balanced across zones.
◆ Current state
Skipper, Zalando's HTTP router and Kubernetes ingress, tags a release for nearly every merge, so most entries are dependency bumps. The substantive ones this autumn are about zone-aware routing: v0.28.56 made routesrv recompress only zones whose routes changed, and v0.28.60 on November 2 serves zone-filtered routes only when skipper-ingress is balanced across zones, falling back to the global table otherwise.
◆ Where it's heading
Zone-aware routing is being made safe for production, with guards against skew and fixes for a data race and silent misconfiguration. It currently works only in the routesrv mode, and the release notes say the direct Kubernetes mode needs the same filtering.
◆ Prediction
Expect zone filtering to be extended to the skipper-to-Kubernetes mode in a coming tag, as the v0.28.60 notes say is needed.
