What is OpenBB?

OpenBB now ships two products from one repo — a Python platform and a desktop app that reached 1.0.

The release feed carries two independent trains. The OpenBB Platform Python package moved 4.6.0 to 4.7.0, cutting Python 3.9, removing the Account Module and HubService, and picking up Python 3.14 and Pandas 3.0 support. Alongside it, the Open Data Platform Desktop app went from test pre-releases in October 2025 to a 1.0.0 GA and two maintenance patches. A rolling 'Latest Stable' tag sits on top of the desktop train purely as an auto-updater pointer, not as a release of its own.

What is Kill Bill?

Kill Bill's 0.25 line advances in tagged silence while 0.24 gets the documented fixes.

Three 0.25.x tags landed in the last five weeks, each published as a bare maven-release-plugin tag copy with no release notes at all. The substantive documentation sits on the 0.24 branch, where 0.24.18 reworked invoice failure handling with retries, uniform WARN logging, and account parking on unrecoverable invoice exceptions, and 0.24.19 limited itself to a Shiro update and dropping Joda from the Java client. The newest versions are the least legible ones.

OpenBB now ships two products from one repo — a Python platform and a desktop app that reached 1.0.

◆ Current state

The release feed carries two independent trains. The OpenBB Platform Python package moved 4.6.0 to 4.7.0, cutting Python 3.9, removing the Account Module and HubService, and picking up Python 3.14 and Pandas 3.0 support. Alongside it, the Open Data Platform Desktop app went from test pre-releases in October 2025 to a 1.0.0 GA and two maintenance patches. A rolling 'Latest Stable' tag sits on top of the desktop train purely as an auto-updater pointer, not as a release of its own.

◆ Where it's heading

Both trains are trimming rather than adding. The platform has removed an account layer, a hosted service module, a data provider, and a Python version across two releases, while shipping a cookiecutter that pushes extension-building onto third parties. The desktop app's post-1.0 work is dependency hygiene and environment-setup reliability. The shape is a project narrowing its own maintained surface and handing the edges to packagers and extension authors.

◆ Prediction

The feed has been silent since late April, so the next move is genuinely unclear from these entries — a 4.8.0 continuing the removals and a matching desktop patch is the pattern, but nothing here explains the three-month gap.

5.0

Kill Bill's 0.25 line advances in tagged silence while 0.24 gets the documented fixes.

◆ Current state

Three 0.25.x tags landed in the last five weeks, each published as a bare maven-release-plugin tag copy with no release notes at all. The substantive documentation sits on the 0.24 branch, where 0.24.18 reworked invoice failure handling with retries, uniform WARN logging, and account parking on unrecoverable invoice exceptions, and 0.24.19 limited itself to a Shiro update and dropping Joda from the Java client. The newest versions are the least legible ones.

◆ Where it's heading

This reads as a maintenance-mode billing core: 0.24 remains the documented, operator-facing branch while 0.25 advances as plumbing nobody writes up. The one behavioral change that genuinely needs operator attention, accounts being parked on any invoice exception by default, arrived on 0.24 rather than the newer line. Nothing across these entries points at new billing capability; the work is error handling, indices, and dependency currency.

◆ Prediction

Expect 0.25.x point tags to keep arriving without notes, with anything operators must know documented on the 0.24 line instead. What 0.25.0 actually changed is not recoverable from these entries.
