MIRA v0.300.0 — public beta

The current public-beta build of MIRA — a self-hostable, single-binary personal AI agent that runs on hardware you control. A project of Vexillon. Licensed under AGPL-3.0-or-later.

⚠️ Public beta (pre-release). Recommended build for new installs; supersedes v0.299.0.

This release is a focused hardening pass across providers and tooling — making tool calls portable, provider errors legible, and health signals trustworthy.

Tool calls that travel between providers

  • Tools are now defined in a portable schema dialect, with a registration-time linter that warns whenever a tool — including one from an MCP server — uses something a provider can't accept. Provider conformance tests keep it honest.

The provider you pick is the provider that runs

  • The model provider you select in the web UI now drives the entire turn for every provider. Previously only some providers were routed correctly; now the choice is always respected.

Clearer failures

  • Provider errors are surfaced uniformly and legibly. When failover kicks in, each provider's reason is aggregated, and every turn ends with a concise summary line — so you can see exactly what happened and why.

Trustworthy health signals

  • A primary provider going down is now raised as a persistent health degradation that auto-clears on recovery, instead of a transient blip.

Caching that stays warm

  • Prompt caching now keeps the tool set stable across a conversation — adaptive tool selection no longer quietly defeats the cache.

Catch bad models at config time

  • Saving a provider now runs a real 1-token generation test, catching deprecated or unauthorised models that a plain catalog listing would miss.

Fewer false alarms

  • The built-in supervisor's restart-loop detector now counts only unclean restarts, and a normal SIGTERM takes the graceful-shutdown path — so routine restarts stop tripping false warnings.
