The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.10.0] - 2026-01-03

Changed

  • Architecture: Completed RFC-23 Dual-Mode Syscall Bridge.
    • Implemented "Smart Mode" switching: Inline (CLI), Client (Pipe), and Daemon (Service).
    • Added Syscall.Authenticate and Syscall.Shutdown for secure daemon lifecycle.
  • Protocol: Refactored OsEvent to OsMessage (RFC-0024).
    • Adopted CQRS schema: kind (command/query/event), type (topic), data (payload).
    • Aligned with Web Worker semantics (worker.postMessage).
  • Transport: Implemented RFC-0025 BlobPointer for efficient binary transfer.
  • Refactor: Renamed kernel components to match the "Browser/Worker" mental model:
    • bridge -> transport
    • daemon -> worker
    • client -> main
  • Verification: Verified 100% test coverage (47/47 tests) with the new architecture.

[0.9.0] - 2025-12-24

Changed

  • Architecture: Implemented "Service Locator" pattern for Kernel Tools (self-configuration via KV).
  • Isolation: Enforced W3C Storage Partitioning via Deno --location <origin>.
  • Bootloader: Added origin parameter to separate Code Source (root) from State Scope (origin).
  • Kernel ABI: Renamed pwosExec to pwosSyscall to reflect the Monolithic Dispatch architecture.
  • Implementation: Renamed exec.ts to syscall.ts as the Unified Entry Point.
  • Documentation: Updated all RFCs and Architecture docs to reference pwosSyscall and syscall.ts.
  • Verification: Achieved 100% Unit Test coverage for the Kernel.
  • Process: Added RFC 0021: Spec-Driven Verification to mandate Spec-Driven Verification.

[0.8.1] - 2025-12-23

Changed

  • Maintenance: Version bump to 0.8.1.

[0.8.0] - 2025-12-23

Changed

  • RFCs: Standardized all RFCs to "Component-First" naming convention and "PromptWar̊e ØS" branding.
  • Validation: Added rfcs/validate.test.ts to enforce RFC standards in CI.
  • Documentation: Updated AGENTS.md with new RFC process rules and version bump protocol.
  • Security: Added RFC 0016: Ring -1: The Vault Primitive defining the security layer.
  • Process: Updated RFC 0000 to be the "Supreme Law" for RFC management.

[0.7.0] - 2025-12-22

Changed

  • Kernel: Renamed all system calls to pwos* prefix (e.g., osExec -> pwosExec) to prevent LLM hallucinations and improve observability.
  • Security: Implemented "Security Watchdog" in KERNEL.md to detect and panic on unauthorized read_file access to System Space.
  • Testing: Added os/agents/hello.md and os/agents/diagnostic.md for system self-verification.
  • RFC: Added RFC 0015: Kernel Architecture defining the "Prompts as Binaries" model.

[0.6.0] - 2025-12-22

Changed

  • Architecture: Refactored to "Monolithic Kernel" architecture.
    • Replaced deno-exec.ts (Supervisor) with exec.ts (Unified Kernel Entry Point).
    • osExec is now the single privileged execution choke-point.
  • Kernel: Simplified KERNEL.md definitions.
    • Switched to arrow functions (const name = async (...) =>) for cleaner syntax.
    • Removed explicit Promise<any> return types where possible.
    • Simplified argument serialization using JSON.stringify.
  • Syscalls: Standardized all syscalls (resolve, ingest, memory) to export default functions and accept injected root context.
  • Cleanup: Removed obsolete goodwin.ts and deno-exec.ts.

[0.5.0] - 2025-12-21

Changed

  • Architecture: Upgraded to "Microservices Architecture" (Pure Unix).
    • Split monolithic syscall.ts into atomic tools: resolve.ts, ingest.ts, memory.ts.
    • Introduced deno-exec.ts (Supervisor) to enforce identity constraints.
  • Security: Implemented the Goodwin Check for Cognitive Integrity.
    • Uses Deno KV isolation (--location) to lock agents to their identity.
    • Verifies /proc/cmdline access before every system call.
  • Kernel: Renamed osBoot to startKernel to align with Linux conventions.
  • Persistence: Kernel parameters (mounts) are now stored in Deno KV at boot and accessed asynchronously by tools.
  • Optimization: Removed boot.ts binary; startKernel now calls memory.ts directly.
  • Documentation: Added blog.md announcing the v0.5 release.

[0.4.0] - 2025-12-20

Changed

  • Architecture: Upgraded to "Promptware/Software Dualism".
    • Promptware Kernel: KERNEL.md (Interface/Intent).
    • Software Kernel: syscall.ts (Implementation/Physics).
  • Kernel: Refactored KERNEL.md to use camelCase (osResolve, osIngest) and osDenoExec.
  • Hardware: Created monolithic os/boot/tools/syscall.ts to handle all low-level operations (resolve, ingest, memory).
  • Path Resolution: Implemented "TypeScript Import" style resolution (relative to __filename) backed by the Software Kernel.
  • Testing: Added syscall.test.ts to verify kernel physics.
  • Cleanup: Removed obsolete linker.ts and memory.ts.

[0.3.0] - 2025-12-20

Changed

  • License: Upgraded to "Public Prompt License - Apache Variant (PPL-A) v0.2".
  • Architecture: Adopted "Bilingual Kernel" philosophy (English for Intent, TypeScript for Precision).
  • Kernel: Refactored KERNEL.md to use "Literate TypeScript" blocks for system call definitions (os_resolve, os_memory, etc.).
  • Bootloader: Updated LOADER.md to use TypeScript expressions for URI construction (new URL(...)) to eliminate ambiguity.
  • Terminology: Standardized on URI (instead of URL) and Ingest (instead of Fetch/Read) across the system.
  • Versioning: Locked bootloader root to refs/heads/main for immutable infrastructure.

[0.2.0] - 2025-12-19

Added

  • Kernel Memory: Implemented os_memory syscall and memory.ts tool to persist critical state using Deno KV with --location based isolation.
  • JIT Linker: Added os/boot/tools/linker.ts to automatically hydrate skills and tools descriptions in Markdown files upon ingestion.
  • VFS Mounts: Added fstab-like support via mounts in Bootloader configuration, enabling mapping of remote URLs to local virtual paths.
  • Skill Specification: Added os/skills/skill-spec/SKILL.md to define the standard for Agent Skills.
  • Tool Standards: Enforced "Dual-Mode Architecture" (CLI + Module) and JSR usage for all system tools in AGENTS.md.
  • License: Added LICENSE file with "Public Prompt License - MIT Variant".
  • Agents: Added initial versions of Felix (Engineer) and Pandora (Researcher) agents.
  • Landing Page: Added index.html for the Promptware OS landing page.

Changed

  • License: Upgraded LICENSE to "Public Prompt License - MIT Variant (PPL-M) v0.2".
  • Architecture: Moved KERNEL.md and tools/ from os/kernel/ to os/boot/ to align with the bootloader sequence.
  • Kernel: Refactored KERNEL.md front matter to use "Directive Style" for system calls (os_resolve, os_invoke, os_ingest).
  • Bootloader: Updated LOADER.md to enforce the "Ingest and Adopt" philosophy and improved error handling.
  • Naming: Unified all system calls to use the os_* prefix (e.g., sys_resolve -> os_resolve).
  • Documentation: Renamed project to "Promptware OS" and updated README.md with author and blog details.
  • Dev Container: Renamed container to "Promptware OS" and added npm package support.

Fixed

  • Context Drift: os_resolve now uses Bootloader Front Matter as the "Source of Truth" for root and mounts, ensuring immutable infrastructure and preventing hallucinations.
  • Tooling: Refactored memory.ts to use jsr:@std/cli and jsr:@std/fs instead of deprecated deno.land imports.

[0.1.0] - 2025-12-07

Added

  • Initial release of Promptware OS architecture.
  • Basic KERNEL.md with VFS and execution laws.
  • LOADER.md bootloader specification.
  • Powell agent as the reference implementation.
