What is Browser Use?
Browser Use agents can now run on a schedule and work ahead of you, stopping only to get approval
Browser Use is a cloud platform for browser-driving agents, and the August 16 release moves it from on-demand runs to standing automation. V4 agents can be scheduled with pause and resume controls, Automation gets its own entry in Run Settings, and a new Agency skill lets an agent research and prepare work on its own, coming back with follow-ups and asking for approval only before an external action such as sending or publishing. AgentMail is enabled for API runs, agents can configure and disconnect Composio triggers themselves, and bu-2-0-mini-preview joins the model picker while MiniMax M3 leaves it. This lands a week after the X402 release rewrote the free-versus-paid boundary around per-browser-open metering.
What is RDKit?
Quarterly majors set the breaking changes; the patch train spends the rest of the year on stereochemistry
RDKit runs a strict quarterly cadence — a 2026_03 major followed by monthly patch releases through the quarter. The major carried the breaking changes: Dict keys moved to std::string_view, SMARTS AND-query merging, _CIPRank no longer set by default on molecules without chiral centers, altered hydride removal, and MolToSmarts no longer adding implicit hydrogens. Every patch since has been dominated by stereochemistry correctness and drawing options, with steady performance work on CIP labelling and synthon substructure search.

Browser Use agents can now run on a schedule and work ahead of you, stopping only to get approval
◆ Current state
Browser Use is a cloud platform for browser-driving agents, and the August 16 release moves it from on-demand runs to standing automation. V4 agents can be scheduled with pause and resume controls, Automation gets its own entry in Run Settings, and a new Agency skill lets an agent research and prepare work on its own, coming back with follow-ups and asking for approval only before an external action such as sending or publishing. AgentMail is enabled for API runs, agents can configure and disconnect Composio triggers themselves, and bu-2-0-mini-preview joins the model picker while MiniMax M3 leaves it. This lands a week after the X402 release rewrote the free-versus-paid boundary around per-browser-open metering.
◆ Where it's heading
Two consecutive releases have built the same thing from opposite ends: pricing that assumes a program is the buyer, and now runtime behaviour that assumes nobody is watching. Scheduling, self-managed Composio triggers, and mail on API runs are the pieces an agent needs to operate between human sessions rather than inside one, and the approval gate on external actions is where the human is being put instead. The model picker is being pruned rather than expanded - one preview model in, one third-party model out - which reads as consolidation onto its own model line.
◆ Prediction
Expect the approval gate to develop into a reviewable queue of pending agent actions, and scheduling to gain finer controls now that V4 agents sit alongside legacy jobs; whether the Agency skill becomes the default agent behaviour rather than an opt-in skill is not visible in these entries.

Quarterly majors set the breaking changes; the patch train spends the rest of the year on stereochemistry
◆ Current state
RDKit runs a strict quarterly cadence — a 2026_03 major followed by monthly patch releases through the quarter. The major carried the breaking changes: Dict keys moved to std::string_view, SMARTS AND-query merging, _CIPRank no longer set by default on molecules without chiral centers, altered hydride removal, and MolToSmarts no longer adding implicit hydrogens. Every patch since has been dominated by stereochemistry correctness and drawing options, with steady performance work on CIP labelling and synthon substructure search.
◆ Where it's heading
Two threads run through the patch train. Stereochemistry is the persistent bug surface — atropisomers, E/Z retention through CDXML and fragment extraction, ring-bond consistency in the bounds matrix builder, aromaticity in polycyclic conjugated systems — which is what happens when a cheminformatics toolkit is the reference implementation everyone's edge cases land on. Separately, search and conformer generation keep getting faster: synthon substructure search doubled, CIP labelling stopped computing auxiliary descriptors unnecessarily, and ETKDG gained all-in-one coordinate refinement.
◆ Prediction
Expect the 2026_03 line to keep receiving stereochemistry fixes until the next quarterly major, which is where any further backwards-incompatible API changes will be batched.
