Pluto v1.0.0 (blake-burns-technologies)

ⓘ Compiled against the MSVC runtime. Windows Defender may scan the binary on first run — this is normal for unsigned executables. Build from source with cargo build --release if you prefer a locally-signed binary.

Build from source — requires Rust 1.75+
# Clone or unzip the source
$ curl -L -o Pluto.zip https://blakeburnstechnologiesinc.com/Pluto.zip
$ unzip Pluto.zip && cd Pluto-v1.0/pluto_installer

# Install Rust if needed
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Build release binary and place it on the path automatically
$ cargo run

Required Cargo dependencies: logos 0.14, crossbeam 0.8, regex 1. All resolved automatically by Cargo.

v1.0 latest stable May 19, 2026 First stable release. All phases 0–6 complete. RASP engine, actor scheduler, native AOT compilation. Details ▾
Changelog
  • ✦
    Phase 6 complete — full time features, actor-model concurrency: spawn, send, receive. M:N scheduler with deadlock detection and poison-pill shutdown.
  • ✦
    Taint tracking — parallel taint_stack / taint_locals in the VM. Every string from I/O is marked tainted and normalized before RASP checks.
  • ✦
    RASP normalization pipeline — iterative URL-decode (≤8 passes; over-encoding = block), unicode fullwidth fold, null-byte strip, HTML entity decode, whitespace collapse.
  • ✦
    true / false keywords — Boolean literals added. orbit (true) { ... clip } now works as an infinite loop with break.
  • ✦
    clip keyword — break out of the innermost orbit. Compile-time patched jump; clip outside any loop is a compile error.
  • ✦
    Native AOT compilation — pluto compile serialises bytecode + function tables and builds a standalone Rust binary. Bytecode format v2.
  • ◆
    Inherited fields — capsule constructors now walk the full inheritance chain. Parent fields are included when constructing child capsule instances.
  • ◆
    Mutable upvalue writeback — CallFrame now stores closure_heap_idx. On Return, mutated upvalues are written back to the heap closure object.
  • 🛡
    80+ RASP rules — expanded WAF bypass patterns: MySQL inline comments, decimal/hex/octal SSRF IPs, DOM sinks, polyglot XSS, SSTI engines, LDAP variants.
v0.9.0 pre-release April 30, 2026 Phase 4 complete. RASP engine, filesystem, networking, GC. Actor concurrency in beta. Details ▾
Changelog
  • ✦
    Phase 4 I/O — fs.airlock, fs.write, fs.exists, fs.delete, net.fetch, net.post, TCP server primitives.
  • ✦
    Capability system — permit declarations checked at compile time by the semantic analyzer.
  • ✦
    Mark-sweep GC — automatic heap management for capsules, lists, and closures.
  • 🛡
    Initial RASP rules — path traversal, sensitive file blocks, SQL injection, XSS, command injection, SSRF, XXE, LDAP.
  • ◆
    Serialize v1 — bytecode serialization for pluto compile AOT path.

v0.5.0 archive March 8, 2026 Phases 0–3 complete. Capsule inheritance, explore/divert, pattern matching. No I/O yet. Details ▾
Changelog
  • ✦
    Phase 3 complete — explore/divert, jettison, match with 5 pattern kinds.
  • ✦
    Full capsule system — fields, methods, single inheritance, super dispatch, closures with upvalue capture.
  • ✦
    Parser & compiler stabilised — recursive descent parser, bytecode emitter with constant pool, stack VM.
  • ◆
    Fixed merge_chunk not remapping RegisterClass constant indices during capsule compilation.

Changelog
  • ✦

  • ✦
    Closures — fn(params) { body } literals with upvalue capture.
  • ✦
    Lists — heap-allocated heterogeneous lists with index access.
  • ⚠
    No capsules, no error handling, no I/O. Source-only release.
