TechScript Release Notes

Release history for the TechScript compiler, runtime, standard library, and developer tools.

TechScript 2.0.1 (Stable Release & Language Spec Lock)

Release date: 2026-10-27 Release tag: v2.0.1 Compatibility line: v2.0.x

This milestone release locks the canonical TechScript language syntax specification across all compiler crates, implements full conformance verification across all 100 official examples, delivers the pure-TechScript AppForge mobile engine with liquid glass UI on Android, and packages the verified production release APK.

Key Highlights

  • Authoritative Canonical Syntax Locking: Fully unified grammar across lexer, parser, semantic analyzer, interpreter, and VM:
    • Variable declaration with is (count is 0) and reassignment with becomes (count becomes count + 1).
    • Constant declarations using constant name is value.
    • Functions declared using to name(params): with colon and 4-space indentation.
    • Return statements using return and output using say.
    • Native double-quoted string interpolation ("Value: {val}") with escaped braces (\{, \}) and automatic literal fallback for raw JSON.
    • Loops with repeat N times:, for item in collection:, and while condition:.
  • Compiler & Lexer Fixes:
    • Implemented top-level and DSL block dedent token consumption in parser, resolving expression parsing conflicts.
    • Enhanced lexer string scanner to distinguish raw JSON curly braces from expression interpolation blocks.
  • 100% Example Verification:
    • All 100 official TechScript examples (examples/01_display/ through examples/10_cli_tool/ + WebForge + AppForge) verified and passing (100/100 PASSED) via tsc run.
  • AppForge Native Android Release APK:
    • Compiled and verified dist/TechScript-AppForge-v2.0.0-release.apk (30,529,303 bytes).
    • Production v2 signature verified using apksigner with SHA-256 certificate thumbprint: 02:27:B2:0B:40:23:AC:AF:32:66:DB:D9:89:CE:D1:31:B8:9B:AA:E4:06:4F:A7:5E:43:19:9F:61:90:EA:E0:57.
    • Fully tested on physical Android device (10ME8DF1CT0001Z, Android 14, arm64-v8a).
  • CI/CD & Repository Security:
    • Multi-platform GitHub Actions workflows updated for Ubuntu, Windows, and macOS.
    • Protected private keystores (*.jks, *.keystore) and Android local.properties in .gitignore.
    • Canonical website and repository URLs verified (https://techscript.is-a.dev/techscript/).

TechScript 2.0.0.1

Release date: 2026-09-15 Release tag: v2.0.0.1 Compatibility line: v2.0.x

This is a maintenance revision for TechScript 2.0. It keeps the 2.0 language and bytecode contracts stable while improving tooling, security checks, performance, and regression coverage.

New in This Revision

  • Added tsc lint --fix for safe, automated lint corrections.
  • Expanded tests for AST construction, JSON parsing, runtime behavior, web error paths, and standard-library registration.
  • Added registration and behavior coverage for database, CSV, JWT, PDF, FTP, math, Redis, Excel, Word, barcode, graphics, and notification modules.

Fixes and Security

  • Added missing capability enforcement for web servers, notifications, canvas saves, and process-backed operations.
  • Fixed command-injection risks in the doctor command and Windows notification handling.
  • Corrected loopback IP validation and broken documentation links.

Performance and Maintenance

  • Reduced avoidable allocations in formatter, VM debugger, bytecode disassembler, LSP, IR, SQLite, package-manager, and standard-library hot paths.
  • Optimized IR predecessor mapping, diagnostic quick-fix lookup, LSP character lookup, SQLite query preparation, and capability validation.
  • Refactored large compiler, standard-library, DSL, resolver, packager, and CLI functions without changing public behavior.

Compatibility

  • Existing TechScript 2.0 source and bytecode contracts remain unchanged.
  • Cargo packages remain at SemVer 2.0.0; 2.0.0.1 is the release revision tag used for packaging and publication.
