  1. Funding

    E2B raises a $21M Series A

    Insight Partners led a $21M Series A into E2B, the open-source sandbox provider most agent frameworks default to. It funds the Apache-licensed self-hostable core that is E2B's main structural advantage over the closed platforms chasing it on boot time.SourceLogged in the sandbox providers comparison

How this changelog is kept

Events are written by hand and dated to the day the change took effect, not the day we noticed. Each one names the tools it affects, so a shared change — a cloud provider raising egress prices across four products — appears on every profile it touches rather than being duplicated four times.

Everything here also flows into the site-wide changelog, which is the cross-tool feed of what is moving in developer infrastructure pricing.
