Modbus Poll 2.0 is our biggest update yet. MULTIPLE TABLES • Monitor several devices or register blocks at once, each in its own tab. • Every tab keeps its own slave ID, address range, poll interval, aliases, formulas, and formats. • Double-click a tab to rename it, e.g. "Inverter" or "Energy Meter". • Status lights on each tab show at a glance which device is responding. A CONNECTION PER TAB • Mix Serial RTU and Modbus TCP devices in one session. • Tabs on different ports or hosts are polled in parallel. • Tabs sharing one RS-485 port take turns automatically, with a notice when a port is shared or its line settings don't match. SAVE & OPEN CONFIGURATIONS • Save every tab, connection, and MQTT setting to a file with Save Config or Save As, and reopen it anytime. • The file name is shown in the toolbar, marked "(unsaved)" when there are changes. • You're asked to save before closing if there are unsaved changes. • Your tabs and settings are also remembered between launches. IMPROVEMENTS • 32-bit formats are now labeled Int32 and UInt32, making unsigned values such as serial numbers easy to read without formulas. • CSV logging and MQTT publishing now include data from all tables. • Number fields apply your input as you type. • Fixed format menus being cut off at the window edge and closing when scrolled.

- Slave ID field now supports the full 1–255 range in TCP mode (Modbus TCP unit ID convention), while RTU stays capped at 1–247. - Fixed a layout issue where dropdown fields (e.g. in Write Register) could get cut off at narrower window sizes.

- NEW: Real-time MQTT publishing — stream live register readings to any MQTT broker (with TLS and authentication support), so you can feed dashboards, Node-RED, Home Assistant, or any automation pipeline instantly. - NEW: Per-register display format override — set a custom format (Signed, Float, Double, etc.) for individual registers, independent of the global display setting. - NEW: Real-time CSV data logging — export live register readings straight to a CSV file (opens directly in Excel) as they arrive, with no size limit. - Added support for hexadecimal address input (e.g. "E376H" or "0xE376") in Start Address, Write Address, and Scan Address fields. - Added a full register display format menu (28 formats): Signed, Unsigned, Hex, Binary, 32-bit Long (signed/unsigned), 32-bit Float, 64-bit Integer (signed/unsigned), and 64-bit Double — each with the 4 standard byte-order options (AB CD / CD AB / BA DC / DC BA). - Added a Combined Chart view — overlay up to 8 registers on a single graph with a toggleable legend, for easy side-by-side comparison. - Expanded the built-in TCP Server Simulator to the full 0–65535 register range, and increased max Quantity for Read Coils / Read Discrete Inputs to 2000. Thanks for your feedback — keep it coming!

- NEW: Real-time CSV data logging — export live register readings straight to a CSV file (opens directly in Excel) as they arrive, with no size limit. Perfect for long-running data collection and analysis. - Added support for hexadecimal address input (e.g. "E376H" or "0xE376") in Start Address, Write Address, and Scan Address fields. - Added a full register display format menu (28 formats): Signed, Unsigned, Hex, Binary, 32-bit Long (signed/unsigned), 32-bit Float, 64-bit Integer (signed/unsigned), and 64-bit Double — each with the 4 standard byte-order options (AB CD / CD AB / BA DC / DC BA). - Added a Combined Chart view — overlay up to 8 registers on a single graph with a toggleable legend, for easy side-by-side comparison. - Increased maximum Quantity for Read Coils and Read Discrete Inputs to 2000, and expanded the built-in TCP Server Simulator to the full 0–65535 register range. - Fixed the TCP Server Simulator so it now works correctly in this sandboxed release, including its Random Data Generator. - Changed the default Server/Client port from 502 to 5020 and default host to 127.0.0.1, since ports below 1024 aren't permitted in the sandboxed macOS App Store build — you can still connect to real devices on port 502 by entering it manually.

- Added support for hexadecimal address input (e.g. "E376H" or "0xE376") in Start Address, Write Address, and Scan Address fields — no more manual hex-to-decimal conversion needed. - Increased maximum Quantity for Read Coils (FC01) and Read Discrete Inputs (FC02) to 2000 registers, matching the Modbus protocol limit for bit-based reads. - Expanded the built-in TCP Server Simulator to support the full register address range (0–65535), up from 256. - Fixed an issue where the Random Data Generator in Server mode could fail to generate data when covering large address ranges. - Added a full register display format menu (28 formats): Signed, Unsigned, Hex, Binary, 32-bit Long (signed/unsigned), 32-bit Float, 64-bit Integer (signed/unsigned), and 64-bit Double — each with the 4 standard byte-order options (AB CD / CD AB / BA DC / DC BA). - Added a Combined Chart view — overlay up to 8 registers on a single graph with a toggleable legend, to compare related values side by side.

• Register Aliases — Give any register a custom name (like "Temperature" or "Humidity") so results are easy to read at a glance instead of raw addresses. • Custom Formulas — Convert raw register values into real-world units with simple formulas like x/10 or (x-32)*5/9. Applies in both the table and chart view, with the raw value still shown for reference. • Live Charts — New Chart view with real-time trend lines for every register, including min/max range and a hover tooltip showing the exact value and time. • Expandable Charts — Tap any chart to expand it full-width with proper axis labels for a closer look at the data.

Fix minor issue

• Built-in Modbus TCP Server Simulator — run a Modbus slave directly from the app, no hardware needed. • Random Data Generator — auto-randomize register values on a configurable interval to simulate live device data. • Client/Server toggle moved to the right side of the header for a cleaner layout. • Bug fixes and performance improvements.

- Added dark and light mode — switch themes from the toolbar, preference saved automatically - Improved UI consistency across all panels - Bug fixes and stability improvements
