OctoPrint 2.0 is on its seventh release candidate, still with no final date.
OctoPrint 2.0 makes serial one connector among several, including Moonraker and Bambu, and removes deprecated plugin APIs. Release candidates have arrived every few weeks since April: rc5 in August fixed config and schema regressions, and rc6 and rc7 in October carried only the standard warning that a candidate may need a manual downgrade.
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.
OctoPrint 2.0 makes serial one connector among several, including Moonraker and Bambu, and removes deprecated plugin APIs. Release candidates have arrived every few weeks since April: rc5 in August fixed config and schema regressions, and rc6 and rc7 in October carried only the standard warning that a candidate may need a manual downgrade.
The 2.0 line is in a long stabilisation, with each candidate fixing regressions and asking testers to cover the new connectors. The thin notes on rc6 and rc7 suggest the remaining changes are small.
A 2.0.0 final is likely within a few candidates; the exact date is unclear from the entries.
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.
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.
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.
