Changelog

Release history of ComIO.Studio — newest first.

1.1.9 2026-09-22

Improvements

• Save session and Load session in the File menu — keep a whole recording in a file, open it again later or send it to someone else.
• A loaded recording behaves like live traffic: you can read it in any display mode.

1.1.8 2026-09-22

Improvements

• Modbus RTU: the send bar and the terminal now know every public function code of the standard (01–08, 0B, 0C, 0F, 10, 11, 14–18, 2B), each with its own field names — codes such as 08 (diagnostics) no longer have to go out as a custom function.
• Number format markers in the send bar and in the Modbus view: click `dec` / `hex` in a column heading to convert that column. Numeric fields start in decimal, raw bytes in hexadecimal, and your choice is remembered between sessions.
• One-based addressing (`dec+1`): type register 77 exactly as the device manual prints it and the app sends address 76.
• Signed register values (`±dec`): −100 goes out as `FF9C`, and the Modbus view reads `FF9C` back as −100.
• Modbus exception replies are drawn in the warning colour instead of the error colour — a device saying "no such register" is answering, not failing.
• An incomplete Modbus frame is visible before you send it: the CRC cell stays empty, CMD is disabled, and the heading of the column at fault is highlighted.
• The FC window accepts custom function codes 1–127, the same range as the send bar.
• 3D waterfall chart: the camera travels to a requested angle over a second instead of jumping there.

Fixed

• Terminal history fixes when the application window is covered or minimized.
• Fixes in Modbus frame splitting and in the function list.
• AI assistant: tool card and result handling fixes.
• Stability and consistency fixes across the app.

1.1.7 2026-09-18

Improvements

• Modbus RTU: Master / Slave / Listen mode on the terminal toolbar; the Role column is filled for every frame, and requests are paired with responses when listening in.

Fixed

• Chart display fixes.
• Stability fixes in the Modbus view.
• Security and reliability improvements in the account service.

1.1.6 2026-09-10

Improvements

• Claude Code assistant now shows a clear message and a Sign in button when the session is not active, so signing in no longer requires a terminal.

Fixed

• Security and reliability improvements in the account and licensing service.
• Website performance and consistency fixes.

1.1.5 2026-09-09

Improvements

• Free plan panel display changes.

Fixed

• Stability and consistency fixes across the app.

1.1.4 2026-09-09

Improvements

• Standardized plan verification across all paid features.

1.1.3 2026-09-08

Improvements

• Improved interaction with MCP clients when opening and closing the application window.
• Added a dedicated MCP settings tab to allow tool use, require confirmation, or block access.
• Added confirmation when closing the application during device programming to help prevent accidental interruption.
• Improved log finalization, repeated-send shutdown, and serial connection cleanup when exiting the application.
• Improved response times for follow-up messages in local AI conversations.
• Standardized MCP server availability under the ProBaud plan.

Fixed

• A model deleted from disk disappears from both selection lists instead of lingering
• Improved memory management and conversation continuity with local AI models.
• Improved the accuracy of tool execution status reporting.
• Stability and consistency fixes across the app

1.1.2 2026-09-02

Fixed

• Fixed 3D waterfall chart rendering in application releases.

1.1.1 2026-09-02

Improvements

• Added access to the application’s working folder picker from the title bar and File menu.
• Undo and Redo in text fields across the app, from the right-click menu and from the Edit menu
• Search in the Lua editor with every match highlighted; Ctrl+F no longer opens the browser's own search

Fixed

• Improved access to recordings in Documents, Desktop, and Downloads after granting folder permissions on macOS.
• Opening a recording that fails now says why, instead of looking like a dead click
• macOS permission prompts describe what the app actually does with a folder; the microphone request is gone, since nothing in the app uses it
• Pasting text no longer wipes the undo history

1.1.0 2026-09-01

Improvements

• Added a measurement charts tab with scalar traces, XY plots, and spectrum waterfalls. Saved recordings can be reopened with their colours, units, and axis labels.
• Added support for browsing long recordings with an overview and detailed data when zooming into a selected section.
• Two pin buttons hold either end of the time axis, so a running measurement can travel like tape, stretch as it grows, or stand still while you look at something
• Lua scripts can record measurements and show them on the chart
• Added dedicated terminal views for ASCII, HEX, Modbus RTU, and VT100.
• Improved terminal scrolling performance with large amounts of data.
• Columns, filters and search across the whole buffer, with per-sender counters on the status bar
• Every row unfolds to the raw bytes that went over the wire, and a frame with a bad checksum is marked instead of silently passing
• Sending rebuilt — text and hex side by side in one view with live conversion, so you see both without switching modes
• Modbus RTU frames are filled in as fields and the checksum is calculated for you; sent frames stay in a history you can reopen
• Custom function codes, per-frame line endings, loop sending with its own interval, and sending straight from a file
• The window is now organised into tabs with an icon bar: connection, terminal, macros, triggers, scripts, charts and the programmer each get their own place, two tab groups side by side, and tabs can be dragged where you want them
• Improved logging during data reception and added a warning when disk writes cannot keep up.
• Lua editor in its own tab, with a run button on the bar
• Triggers save the moment you change them and can be added straight from the bar
• The programmer's overlay windows became sections inside its tab
• Connection statistics sit on the status bar instead of taking up a panel
• The AI assistant now receives a description of what each tool returns, loop sending has stated limits, and permission prompts carry a visible countdown
• Refreshed icons, tooltips and controls throughout, with all 19 themes updated to match

Fixed

• Improved persistence of serial port settings across restarts, including externally initiated connections.
• Timestamps come from the port itself, so the terminal and the buffer agree on when data arrived
• Improved splitting of outgoing data at the separator.
• The transmit line ending belongs to the format, so it no longer shows up as a stray character in the terminal
• ASCII shows characters even for data typed in hex, and HEX shows bytes without breaking the row layout
• Selection in the terminal is properly visible, and the scrollbar behaves like a scrollbar — the track jumps the slider to the cursor
• Corrected dropdown and tooltip positioning when using interface scaling.
• Improved the display and handling of consecutive tool approval requests.
• Chart recordings respond to clicks reliably while the list refreshes
• Stability and consistency fixes across the programmer, logging and the Gemini engine

1.0.28 2026-07-28

Improvements

• Improved terminal responsiveness during high-volume data reception, including Modbus RTU communication.
• Messages from Lua scripts now appear as separate lines instead of blending into incoming data
• New example script for checking terminal behaviour, works without a connected device

Fixed

• A reply cut short by the model's output limit now says so, instead of ending silently
• Increased the default response generation limit for cloud AI models.

1.0.27 2026-07-27

Improvements

• New calculation toolbox for the AI — CRC and checksums, Modbus RTU and SLIP frames, number and register conversions, hex dumps, link timing, ASCII/NMEA parsing
• The AI can now stay on a task as long as it needs — no cap on tool calls per message
• Lua scripts can react to raw received bytes, for binary protocols
• Added text extraction from PDF files in the working folder.
• Syntax highlighting for Lua and JSON in tool cards — and in the approval prompt
• Typewriter animation when pasting text

Fixed

• The "taking longer than usual" prompt no longer appears while a tool waits for your approval
• Right-click menu is back in the flash size prompt
• The AI assistant lists all four supported microcontroller families
• More consistent dialogs across the app
