What is Read the Docs?
Read the Docs is rebuilding its build farm around uv and isolated builders, one week at a time.
Weekly date-tagged releases, almost entirely build infrastructure. The visible work is a migration to uv-managed environments and isolated, ephemeral builders, shipped in small increments between routine dependency bumps. The two most recent releases are the quietest of the run: plumbing for uv and build status in one, and a video extension bump, a nullable-field step toward dropping has_valid_clone, and Python 3.14 for the pip-tools workflow in the other.
What is Tango?
Tango is dual-tracking workflow documentation and a browser-based AI CRM agent.
Tango's core surface — capturing browser workflows into step-by-step guides — keeps gaining depth: voice transcription during capture, workflow branching for multiple paths, translations for global teams, video embeds, and governance and compliance views for Enterprise. In parallel, Tango bet hard a year ago on browser-based AI agents with the AI CRM Admin, aimed at sales and revops teams who otherwise spend hours on repetitive Salesforce-style updates. Both bets are still being shipped against, but the cadence on the documentation side is markedly higher.

Read the Docs
5.0COLLAB
Read the Docs is rebuilding its build farm around uv and isolated builders, one week at a time.
◆ Current state
Weekly date-tagged releases, almost entirely build infrastructure. The visible work is a migration to uv-managed environments and isolated, ephemeral builders, shipped in small increments between routine dependency bumps. The two most recent releases are the quietest of the run: plumbing for uv and build status in one, and a video extension bump, a nullable-field step toward dropping has_valid_clone, and Python 3.14 for the pip-tools workflow in the other.
◆ Where it's heading
The isolated builder is the arc worth tracking — private repository support, an ephemeral builder script, and removal of the old scale-in protection path all point at builds that run in disposable environments. Alongside it runs a quieter cleanup pattern: fields are made nullable before removal, feature flags are deleted once the code behind them lands, and Python versions are pushed forward in the tooling before the runtime. User-facing change is rare and arrives as a side effect, as when July's release moved images to Ubuntu 26.04 and Python 3.14.
◆ Prediction
Expect the isolated builder to become the default path and further uv environment fixes; the has_valid_clone column being made nullable signals its removal in a following release. Feature work should stay secondary until that migration finishes.
Tango
1.3COLLAB
Tango is dual-tracking workflow documentation and a browser-based AI CRM agent.
◆ Current state
Tango's core surface — capturing browser workflows into step-by-step guides — keeps gaining depth: voice transcription during capture, workflow branching for multiple paths, translations for global teams, video embeds, and governance and compliance views for Enterprise. In parallel, Tango bet hard a year ago on browser-based AI agents with the AI CRM Admin, aimed at sales and revops teams who otherwise spend hours on repetitive Salesforce-style updates. Both bets are still being shipped against, but the cadence on the documentation side is markedly higher.
◆ Where it's heading
Tango is making documentation deeper and more multilingual while incubating a separate AI-agent product line on top. The implicit thesis is that workflow capture is the moat — anyone can build a CRM agent, but capturing the exact path a human takes and translating it into agent actions is harder. The two surfaces should eventually converge, but right now they look more like a mature product plus a bet than a unified strategy.
◆ Prediction
Expect AI CRM Admin to gain second-system breadth (HubSpot, Outreach, or other revops surfaces beyond Salesforce) and the documentation side to start exposing captures as agent-runnable workflows — using the existing capture data as the substrate for autonomous execution.
