The updated release optimizes read, write, and EventQL performance while packing indexes into fewer files to accelerate queries in high-volume environments. Safeguards now protect operations by enforcing default rate limits, bounding idle connections, limiting query memory, and automatically transitioning to read-only mode during write failures like full disks. A coexisting v2 API introduces structured response bodies, stream heartbeats, and support for the HTTP QUERY method across all eight client SDKs. Furthermore, data management is streamlined via single-line CloudEvents for easier personal data scrubbing alongside incremental backups that record only new events.

EventSourcingDB 1.3.0 is out, and it is faster and more stable than any version before it. Writing and EventQL queries are considerably faster, reading is faster as well, every request is bounded in time, and more than sixty fixes went in. Next to all that, it brings a new API that reports the outcome of every request it accepts in its body and names every error with a code of its own.
This post walks through what changed and what to mind when you upgrade. The v1 API is supported until January 31, 2027, and a later release removes it, so you can move to the new one at your own pace. And from today on, the documentation of EventSourcingDB lives on eventfoundation.io; every old link leads there.
A New API, Built to Last#
The new v2 API runs next to the v1 API, on the same data. Its central idea is simple: once the server has accepted a request, its outcome is in the body. A request counts as accepted when it is authenticated, its body has the shape…
Tech buyers seeking compact power accessories can now find substantial markdowns across high-performance GaN adapters and portable gear. The premium multi-port brick leverages real-time output monitoring while occupying significantly less bag space than conventional hardware. These parallel discounts extend to productivity desktops, mobile stabilizers, and pop-culture building kits at major retailers.
Development teams consistently recognize code evaluations as an essential component of modern software engineering standards. While these assessments safeguard quality, they often demand a significant investment of hours from contributing engineers. Balancing rigorous oversight with daily development speed remains a primary challenge for technical organizations.
Pydantic has stepped in to steward the popular networking ecosystem by launching an independent fork of the original HTTPX project. Operating under modern runtime constraints, the refreshed library addresses corporate environment hurdles by utilizing the host platform's native trust store. This transition secures long-term maintenance while offering high-performance asynchronous and synchronous tooling for contemporary Python applications.
