Gumloop
Gumloop 12.4 lets its agent build custom MCPs for apps the platform doesn't support.
A side-by-side editorial comparison of Buttondown and listmonk — release velocity, themes, recent moves, and the top alternatives to consider.
Buttondown keeps shipping daily fixes, with the iPhone editor getting repeat attention.
Buttondown posts a changelog entry almost every day, mostly user-reported fixes. The past week covered portal sign-in for capitalized emails, iframe-embedded forms, an is_outdated flag for sending-domain DNS records and a send confirmation showing subject and recipient count. October 15 and 16 both fixed iPhone keyboard collisions in the editor, first the insert menu and then the toolbar on long emails.
Only signal in window is an automated nightly build — no curated release to read
The single recent entry is an automated nightly build from the master branch, flagged as potentially unstable. It carries no curated changelog, so there's no user-facing signal to interpret.

October 15 and 16 both fixed iPhone keyboard collisions in the editor, first the insert menu and then the toolbar on long emails.
The product is in a polish phase focused on preventing mistakes and smoothing rough edges. The Gmail clipping estimate, richer send confirmation and outdated-DNS flag catch problems before an email goes out, while back-to-back mobile fixes show writers drafting on phones are now a real use case.
Expect more pre-send safeguards, rendering fixes and mobile-editor polish rather than a large launch; nothing in these entries signals one.

A lone nightly build provides no directional information. listmonk's substantive changes surface in versioned stable releases, none of which fall in this window.
Unclear from a nightly build alone; the next meaningful signal would be a tagged stable release with an actual changelog.
