[3.6.0] - 2026-02-15

Fixes

• Fix a regression with hover formatting

New Features

• Unreferenced label warning can be suppressed with underscore prefix

(universal version will skip this update)

[3.5.0] - 2026-01-11

Fixes

• Fix an issue with error checking of macro arguments

New Features

• Go to references on an ENT will find the corresponding EXT labels
• Hovering on an ENT label will show all the modules where it is used

(universal version will skip this update)

[3.4.0] - 2025-09-28

New Features

• Unreferenced label warnings with accompanying fine grained settings
• Disk image server handles tracks generated by MAME (flux tracks)
• The macro argument count ]0 is better handled (Merlin 16 and above)

[3.3.0] - 2025-02-17

Fixes

• Docstring is shown when hovering on a macro reference
• Conditionals are handled more efficiently and accurately

New Features

• Macro expansions resolve IF and DO in many cases
• Unused macro definitions are identified
• Deferred evaluations in a macro definition are identified

New Behaviors

• Duplicate labels in a macro are allowed, but a warning is given at EOM
• Conditional macro definitions are handled differently
  • they are always discouraged by a warning, see the a2kit::lang::merlin docstring

[3.2.1] - 2025-01-09

Fixes

• Update bundled language server to version 3.5.1
  • fixes label substitution errors in disassembly

(universal version will skip this patch)

[3.2.0] - 2024-11-17

Fixes

• Fix some issues in disassembly workflows

New Features

• Disassembly: data sections can be converted back to code
• Guard against excessive workspace scans
  • maximum directory count and recursion depth
  • passes over build, node_modules, and target directories

[3.1.2] - 2024-09-29

Fixes

• Repair lower case completions logic, takes effect if:
  • completions.lowerCase==true && flag.caseSensitive=="ignore"

[3.1.1] - 2024-09-15

Replace bundled darwin-arm64 server with the correct version.

This patch will be skipped over by all other platforms.

[3.1.0] - 2024-09-15

New Features

• Hovering on an EXT label shows the ENT label's docstring
• Go to... commands behave more correctly
  • Using Go to declarations on a reference to an EXT goes to the EXT
  • Using Go to definitions on a reference to an EXT goes to the ENT
  • Using Go to... from any node is valid, e.g., if we start on a definition and ask for definitions the references are returned. This is the usual VS Code behavior.
• Rename Symbol finds primary workspace symbols
• Additional workspace checks

[3.0.1] - 2024-09-08

Fixes

• Searching for workspace symbols (ENT labels)
• Correct a bug in rename symbol (still scoped to doc + includes, however)
• Correct a bug in address hovers
• Formatting preserves blank lines

[3.0.0] - 2024-08-24

New Features

• Language server is native rust code
• Expanded language diagnostics
  • conditional assembly and folds are handled
  • better handling of 16 bit syntax
  • checks illegal forward references
  • others
• Disk image support is bundled, no need for external a2kit installation
• Better disassembly, finds various data patterns, user can set MX
• Spot assembler to convert code sections to data sections as part of disassembly effort
• Includes with the same name are resolved by partially matching ProDOS and local paths

Breaking Changes

• Platform support works differently
  • Out of the box support for Linux-x64, Mac-x64, Mac-aarch64, and Windows-x64, everything needed is bundled.
  • Universal version requires an external a2kit installation, not only for disk images, but for all services.
• Include file search works differently
  • If the workspace contains two files with the same name, the best partial match to the ProDOS path is selected.
  • If there are multiple equally good matches an error is flagged and the include is not analyzed.
