What is Dovetail?

Dovetail spent July opening doors to other tools; August is spent making its own rooms easier to enter.

Dovetail is a customer-research workspace whose center of gravity has moved to chat and agents. July was an integration run — Snowflake into Channels, a Microsoft Copilot connector, MCP tools inside chat, and a one-click menu for sending work out to Linear or Notion. August contains no new reach at all: every release this month files down the chat and Digital Twin surface that those integrations feed.

What is mcmcensemble?

An ensemble sampler just admitted its walkers were barely talking to each other.

mcmcensemble provides affine-invariant ensemble MCMC samplers — differential evolution and stretch move — behind a single MCMCEnsemble() entry point. The API consolidated in 3.0.0 around a flexible inits argument and a hidden internal surface, with parallelism delegated to the future framework. The 2025 release fixed a defect in the sampling behaviour itself, and results now differ from every earlier version.

Dovetail vs mcmcensemble: editorial side-by-side

Dovetail
ANALYTICS
5.0

Dovetail spent July opening doors to other tools; August is spent making its own rooms easier to enter.

◆ Current state

Dovetail is a customer-research workspace whose center of gravity has moved to chat and agents. July was an integration run — Snowflake into Channels, a Microsoft Copilot connector, MCP tools inside chat, and a one-click menu for sending work out to Linear or Notion. August contains no new reach at all: every release this month files down the chat and Digital Twin surface that those integrations feed.

◆ Where it's heading

The pattern across the last five releases is access, not capability. Digital Twins went from a two-step workaround — make a generic agent, then change its type — to a first-class create option, then gained a share link that lands a recipient in a conversation rather than a configure page. Chat is being simplified along the same line, with a thinner footer and scoped context that survives the jump to fullscreen. Dovetail is preparing these agents for people who will never build one.

◆ Prediction

Expect the sharing path to keep widening — permissions, guest access, or an embed for a twin link — since a link that opens straight into chat only pays off if it can safely leave the workspace.

An ensemble sampler just admitted its walkers were barely talking to each other.

◆ Current state

mcmcensemble provides affine-invariant ensemble MCMC samplers — differential evolution and stretch move — behind a single MCMCEnsemble() entry point. The API consolidated in 3.0.0 around a flexible inits argument and a hidden internal surface, with parallelism delegated to the future framework. The 2025 release fixed a defect in the sampling behaviour itself, and results now differ from every earlier version.

◆ Where it's heading

Development has moved from packaging to statistics. The early releases were about shape: a rename, argument alignment, moving coda to Suggests, adding tests, then parallel execution and named-vector support. The 3.0.0 release closed the API down to one wrapper and generalised initialisation. What is left, as 3.2.0 shows, is the correctness of the sampler itself — walker correlation, ergodicity checks, and grid artefacts in the differential evolution step were all addressed in a single release, all reported by one contributor. The package is being audited rather than extended.

◆ Prediction

Further sampler-behaviour fixes are the most likely next move, since three separate correctness issues surfaced together in the last release and the package's API has been stable since 3.0.0.
