Changelog: v0.x

v0.x Release Series

The v0.x series represents the initial public releases of Trix, establishing the core memory management system for AI applications.

v0.8.0

Released August 13, 2026

Query Language, Browse & Knowledge Navigation

A query language for your memories and a visual way to navigate them — plus richer memory types, revision history, and annotations.

Highlights

• Memory Query Language (MQL) — a compact text syntax to filter, search, and sort memories, with an interactive Query page (syntax highlighting, autocomplete of your real spaces and tags, inline errors, and a plain-English read-out)
• MQL depth — boolean logic, numeric/date ranges, graph traversal (entity / topic / cluster / related), geo (near / bbox), full-text, similarity, and aggregation (count / group by / avg), compiled to safe parameterised SQL on the server
• Natural-language → MQL copilot and an instant rule-based query advisor
• Saved searches — save MQL queries and run them on a schedule with notifications
• Browse — a force-directed graph of your memories with semantic zoom and level-of-detail, plus Wiki, Todos, and Guides views
• Open Knowledge Format (OKF) export — preview and export a whole space as a portable bundle
• Rich memory-type registry and an Action super-type (guides & checklists), with a Now view for what needs attention
• Memory revision history with restore, and inline comments / annotations on memories

v0.7.0

Released July 13, 2026

Retrieval Quality, Chat Tiers & Spaces

A major retrieval-quality overhaul for sharper answers, smart model routing, and big steps forward for spaces, geo, and workflows.

Highlights

• Higher-accuracy retrieval — multi-hop recall, structure-aware query planning, multi-query RRF fusion, and Cohere cross-encoder reranking
• Chat model tiers — BALANCED / FASTEST / CHEAPEST / POWER / BEST presets plus a dynamic router that picks the best-fitting tier per message
• New model provider: xAI (Grok), with declarative price/latency bands and live provider-health-aware routing
• Geo memories — location filters, personal places, and geo clusters
• Spaces — permanent merge, reversible space links, cross-space relationships, and unlimited spaces on paid plans
• Workflows — configurable max concurrent runs, retry from a failed step, and an approvals inbox
• Text-to-speech endpoint with optional save-to-Data, plus an end-to-end backup pipeline
• Broad security hardening across authentication, access control, and SSRF protection

v0.6.0

Released April 1, 2026

Knowledge Tools, Batch Search & Smart Storage

New composite tools for knowledge synthesis, batch search, smart memory storage, and onboarding diagnostics. Available across MCP, all SDKs, and CLI.

Highlights

• Batch search — run semantic, fulltext, and aggregate searches in parallel with deduplication
• Knowledge summary — search and group memories by topic with structured synthesis
• Memory-to-note conversion — promote memories into structured notes organized by tag
• Store and organize — store a memory with enrichment, linking, and clustering in one call
• Setup diagnostics — verify API connectivity with optional round-trip test
• Natural language time filtering on notes and habits ("last week", "in January")

v0.5.0

Released March 27, 2026

Calendar Sync, Export & Security

Calendar-to-memory sync, memory export/backup, HMAC service authentication, cost protection for agents, and comprehensive security hardening across all components.

Highlights

• Calendar-to-memory sync pipeline — automatically import calendar events as memories
• Memory export/backup API endpoint for bulk data export
• Rogue agent cost protection — per-run cost caps and account-level budgets
• Adaptive pipeline router with 5 named presets for retrieval optimization
• Custom hub roles with 48 permission flags and hierarchy enforcement
• Service-to-service authentication upgraded to HMAC signatures (breaking)
• GDPR hard-delete job for complete account data purging

v0.4.0

Released March 9, 2026

Notes, Workflows & Bots

Long-form note editing, bot/agent execution, durable workflow engine, and Anthropic Claude tool integration.

Highlights

• Notes resource — collaborative long-form documents with block-level editing
• Workflow engine — durable multi-step automation with retries and observability
• Bot/agent runtime with skill attachment and scheduled triggers
• Anthropic tool-use integration with auto-discovered MCP tools

v0.3.0

Released February 16, 2026

Tasks, Personas & Chat

Task management, customizable personas, real-time chat, and habit tracking.

Highlights

• Tasks resource with assignees, subtasks, and bot handoff
• Personas — switchable AI configurations per space
• Chat hubs and conversations with file uploads and reactions
• Habit tracking with check-ins, coaching, and analytics

v0.2.0
