What is GLAuth?

GLAuth's September releases are security dependency updates and build fixes.

GLAuth's 2.5.0 in April was the substantial release, adding OpenTelemetry tracing, embedded plugins and RISC-V builds. Since then releases have been corrective: disabled users rejected on all backends in 2.5.1, a release-time plugin check in 2.5.2, a port-handling fix in 2.5.3, and 2.5.4 on September 13 updating all dependencies to safe versions.

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.

0.0

GLAuth's September releases are security dependency updates and build fixes.

◆ Current state

GLAuth's 2.5.0 in April was the substantial release, adding OpenTelemetry tracing, embedded plugins and RISC-V builds. Since then releases have been corrective: disabled users rejected on all backends in 2.5.1, a release-time plugin check in 2.5.2, a port-handling fix in 2.5.3, and 2.5.4 on September 13 updating all dependencies to safe versions.

◆ Where it's heading

GLAuth is in maintenance after 2.5.0, with occasional security and build releases. No new features have shipped since April.

◆ Prediction

Expect occasional 2.5.x security updates; the entries give no sign of the next feature release.

SavvyCal

2.5

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.
