Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.60.1...0.61.0

[0.60.1]

  • Fixed website release builds to mark the pushed tag as the latest docs version so freshly released docs do not show the unmaintained-version banner.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.60.0...0.60.1

[0.60.0]

  • Added a new MagnusOpera.FScript.TypeProvider package that type-checks scripts at compile time and exposes exported functions as strongly-typed F# members with runtime signature compatibility checks.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.59.0...0.60.0

[0.59.0]

  • Removed the obsolete Stdlib shim module and switched embedded-source import errors to generic wording now that stdlib is fully native.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.58.0...0.59.0

[0.58.0]

  • Added String.endsWith to the language/runtime built-ins with corresponding type inference support.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.57.0...0.58.0

[0.57.0]

  • Replaced Xml.deserialize with Xml.queryValues for explicit value extraction from XML strings.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.56.0...0.57.0

[0.56.0]

  • Removed Xml.serialize from runtime externs; Xml.deserialize remains available.
  • Made String.replace, String.indexOf, String.substring, and String.split consistently pipeline-friendly by using data-last argument order.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.55.0...0.56.0

[0.55.0]

  • Escaped pretty-printed string values (including map string keys) so interpolated strings with embedded quotes render unambiguously in CLI/REPL output.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.54.2...0.55.0

[0.54.2]

  • Fixed release marketplace publish jobs to checkout the repository before running local publish scripts.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.54.1...0.54.2

[0.54.1]

  • Fixed NuGet packaging to include the custom package readme as README.md so PackageReadmeFile validation succeeds during pack/publish.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.54.0...0.54.1

[0.54.0]

  • Split VS Code Marketplace and Open VSX publishing into separate release jobs and added idempotent publish scripts so duplicate-version reruns succeed while real publish errors still fail.
  • Updated package/readme wording from immutable-first to immutable-by-design to reflect immutable-only semantics.
  • Switched NuGet package readme for MagnusOpera.FScript.Language and MagnusOpera.FScript.Runtime to a targeted NUGET.md with logo, overview, rationale, and license.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.53.0...0.54.0

[0.53.0]

  • Switched sandbox deny configuration to root-relative glob patterns (HostContext.DeniedPathGlobs), including support for .git and **/node_modules style blocking.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.52.0...0.53.0

[0.52.0]

  • Added Json.serialize and Xml.serialize externs for option-based JSON/XML serialization in runtime hosts.
  • Renamed XML decode extern from Xml.values to Xml.deserialize.
  • Replaced Fs.isFile and Fs.isDirectory with Fs.kind returning stdlib union FsKind (File/Directory/Missing) for direct pattern matching.
  • Added host-configurable sandbox exclusions (HostContext.ExcludedPaths) so Fs.glob/Fs.enumerateFiles hide blocked entries and Fs.readText/Fs.writeText/Fs.createDirectory fail immediately on blocked paths.
  • Added built-in String.* helpers: replace, indexOf, toLower, toUpper, substring, concat, and split.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.51.0...0.52.0

[0.51.0]

  • Added CLI extern configuration flags (--no-default-externs, repeatable --extern-assembly) with attribute-based provider discovery and conflict validation.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.50.0...0.51.0

[0.50.0]

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.48.0...0.48.1

[0.48.0]

  • Switched VS Code extension changelog to a symlink of root CHANGELOG.md so Marketplace/Open VSX release notes use a single shared source.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.47.0...0.48.0

[0.47.0]

  • Publishing to tap requires only sign artifacts.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.46.0...0.47.0

[0.46.0]

  • Enforced compact delimiter layout for non-empty {...} and [...] forms so opening/closing braces or brackets cannot appear on their own lines.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.45.0...0.46.0

[0.45.0]

  • Fixed parser/LSP false "Block cannot end with a let binding" errors for block-scoped let values that contain multiline expression continuations (for example list literals with multiline record items).

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.43.0...0.44.0

[0.43.0]

  • Switched LSP local go-to-definition to lexical AST binding resolution so local symbol usages (including record-field values and edge-of-token clicks) resolve to their exact nearest binder.
  • Added fscript.server.logLevel=debug support to surface detailed definition/references diagnostics and refined definition-follow-up references suppression so declaration clicks still show references while usage clicks navigate reliably.
  • Fixed local match-pattern declaration clicks (for example Some batch) to stop jumping to first usage and preserve references-window behavior.
  • Updated debug logging output to emit LSP window/logMessage entries when fscript.server.logLevel=debug, so logs are visible in editor output.
  • Fixed LSP definition on member-access field names (for example batch.ProjectPaths) to resolve via qualifier type inference (including match-pattern-bound locals).
  • Updated top-level function declaration clicks to preserve references-window behavior by keeping declaration entries in immediate follow-up reference results.
  • Fixed LSP reference indexing to include nameof <symbol> occurrences so top-level declaration clicks surface nameof usages in the references window.
  • Added an independent VS Code/LSP toggle for hover hints so it can be enabled or disabled without disabling the language server.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.42.0...0.43.0

[0.42.0]

  • Added LSP go-to-definition support for local and pattern-bound variable bindings so usages navigate to the nearest in-scope declaration (including function parameters and tuple let destructuring names).

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.41.0...0.42.0

[0.41.0]

  • Added Int/Float/Bool conversion helpers in stdlib-style builtins (*.tryParse and *.toString) for safe scalar parsing and string formatting.
  • Added tuple let destructuring (let (a, b) = ...) for top-level, block, and let-expression non-rec bindings.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.40.0...0.41.0

[0.40.0]

  • Fixed VS Code/LSP analysis to inject a default Env binding so scripts using Env no longer show unbound-variable diagnostics in the editor.
  • Fixed VS Code/LSP type navigation so Env and Environment resolve to the stdlib Environment type definition.
  • Added CLI script argument forwarding with -- and injected Env metadata (ScriptName, Arguments) for file, stdin, and REPL execution modes, with Environment now defined in stdlib for LSP/type visibility.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.39.0...0.40.0

[0.39.0]

  • Added VS Code REPL commands to open FScript REPL, send selected code to REPL, and execute the current script in REPL from the editor.
  • Updated VS Code REPL launch to default to auto, preferring local workspace CLI (dotnet run --project src/FScript) before falling back to fscript on PATH.
  • Fixed VS Code REPL script/selection sending to dedent multiline snippets and wrap non-let snippets in an inner let value block, avoiding premature line-by-line execution and indentation/parser errors for selected inner content while keeping atomic execution and persisting only pure single-let selections.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.38.3...0.39.0

[0.38.3]

  • Updated changelog gating and release preparation so release commits can leave ## [Unreleased] empty without placeholder bullets.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.38.2...0.38.3

[0.38.2]

  • Fixed release-prepare changelog rendering so the post-release initialization bullet stays under ## [Unreleased] instead of being appended to the released section.

  • Added CLI stdin execution support so scripts can be piped to fscript (including -r/--root overrides).
  • Added fscript version command to print the current CLI version.
  • Added interactive CLI REPL mode when running fscript without arguments.
  • Updated REPL multiline submission to require double-Enter for pending blocks and improved function display with typed signatures.
  • Fixed block semantics to reject trailing let-only blocks without a final expression (for example let a = let f x = ...) and require an explicit return expression.

Full Changelog: https://github.com/MagnusOpera/FScript/compare/0.37.0...0.38.0

[0.37.0]

  • Added resolver-backed import loading APIs (parseSourceWithIncludesResolver and ScriptHost.loadSourceWithIncludes) for hosts that load scripts from non-file sources.
