What is constants?

The R package for CODATA constants rebuilt its symbol table on NIST's naming so future updates stop being hand work.

constants exposes the CODATA recommended values of the physical constants to R, as a data frame plus symbol lists that carry units, uncertainties, or both. The package reached 1.0.0 on the 2018 CODATA release and has shipped once since, purely to track a units package update. Its surface is small and its release cadence is bound to CODATA, which revises every few years.

What is Dovetail?

Dovetail is wiring itself into every tool its users already work in, and now pushes back out to them.

Dovetail sits at the center of a heavy integration cycle. Agents reached general availability in July, Channels 2.0 entered closed beta, and Docs went from launch to steady polish. Around that core, the connectors keep multiplying: Snowflake into Channels, HubSpot tickets and contact enrichment, a Microsoft Copilot connector, and MCP tools reachable from chat.

The R package for CODATA constants rebuilt its symbol table on NIST's naming so future updates stop being hand work.

◆ Current state

constants exposes the CODATA recommended values of the physical constants to R, as a data frame plus symbol lists that carry units, uncertainties, or both. The package reached 1.0.0 on the 2018 CODATA release and has shipped once since, purely to track a units package update. Its surface is small and its release cadence is bound to CODATA, which revises every few years.

◆ Where it's heading

The direction set at 1.0.0 was to stop being a curated convenience wrapper and become a mechanical mirror of NIST. Hand-crafted symbol names were replaced with NIST's own ASCII symbols, categories adopted NIST's, and uncertainty switched from relative to absolute — all framed by the maintainer as necessary to make future CODATA updates routine. On top of that the package gained a correlation matrix and optional integration with the quantities package, moving it from a lookup table toward something that can propagate uncertainty.

◆ Prediction

Having rebuilt the symbol table specifically so CODATA revisions become mechanical, the next substantive release most likely tracks a new CODATA dataset rather than adding API. The experimental correlated-value support, disabled by default at 1.0.0, is the one part these entries flag as unfinished.

5.0

Dovetail is wiring itself into every tool its users already work in, and now pushes back out to them.

◆ Current state

Dovetail sits at the center of a heavy integration cycle. Agents reached general availability in July, Channels 2.0 entered closed beta, and Docs went from launch to steady polish. Around that core, the connectors keep multiplying: Snowflake into Channels, HubSpot tickets and contact enrichment, a Microsoft Copilot connector, and MCP tools reachable from chat.

◆ Where it's heading

The product is moving from a research repository to a signal router. Inbound, it pulls from wherever customer signal already lives — warehouses, CRMs, support queues. Outbound, one-click actions now send a Doc, data point, or Channels idea straight into the tool where the work happens. The AI layer is being tuned rather than expanded: project-level context is a briefing step that shapes classification quality before the model touches the data.

◆ Prediction

Channels 2.0 graduating from closed beta is the obvious next milestone, and the one-click action menu is the natural place for more destinations to land. More warehouse and CRM sources are likely given the Snowflake and HubSpot pattern.
