What's new

Every release replaces the previous one — the editor's update check offers it automatically, and a project saved in an older version always opens in a newer one.

Starting with 1.00.001, versions are plain numbers in the form generation.feature.build: the last field counts builds, the middle one grows with new capabilities, the first one practically never moves. Releases before that carried dates (year.month.day.build).

Everything fits in ladder now. Function blocks with state — timers, counters, ramps, filters, hysteresis — sit in a rung as EN boxes with the standard IEC 61131-3 EN/ENO behaviour: the block simply does not execute while the rung is off, its state freezes and its outputs hold.

LD ↔ FBD switching — right-click a program in the tree and open it in the other editor. Ladder always opens as FBD; FBD opens as ladder whenever the network fits rung form, and if it does not, the status bar names the exact block that is in the way.
Trends with up to 4 curves in one chart, each with its own color — on the panel and in the browser alike.
Gauge: arc thickness is adjustable and the needle can be switched off for a clean modern look.
Alarm table: row text size is selectable; the row height and the touch target scale with it.
Toolbar: New, Open, Save, Undo in the expected order, icons properly centered.
The Run/Step controls of the block editor appear only while the simulation is on — online they had no business being there.
CANopen: the SDO parametrization picker now offers every writable object of the device dictionary, not only the non-mappable ones — ramp times and friends included.
The online activity bar in the status line sweeps at the real polling rate of the link: one sweep is one read cycle, a stalled panel leaves the bar standing full.

The editor build is signed again and the update manifest with it.
First version of the activity bar and the LD/FBD context-menu switch.

2026.08.20.1

ESP32-P4 support. The Waveshare P4-NANO with the 10.1" MIPI-DSI touch panel (1280×800) is a supported target with a precompiled runtime in the installer: display, touch, Ethernet and WiFi work out of the box.
Upload over the network. The panel accepts a visualization pack over Ethernet or WiFi (POST /upload), with exactly the same safety as over USB: the pack lands in the inactive slot, is fully validated, and only then does the panel switch — an upload can never brick a panel.
On the P4 the panel serves the WEBview over Ethernet and its own WiFi access point at the same time; packs on the P4 may be up to 4 MB (room for photo-heavy screens), with an 8 MB decoded-image cache in PSRAM.

Online, offline and simulation are now three separate things. Going online never silently switches the editor into simulation; the transport controls show only when the simulation is on.
Five sizes of quality text (13/15/18/20/22/24/28/36 px plus the numeric and seven-segment faces), TTF import for custom fonts, and full Slovak diacritics everywhere.
I2C toolbox: a bus scanner in the editor, an address dropdown fed by the chip catalog, and automatic chip identification where the silicon supports it.
The device Resources page was decluttered; column widths are draggable; device renames propagate everywhere.

S3 panels run their PSRAM at the full 80 MHz — measurably smoother screens on photo-heavy projects.
The editor flashes runtimes itself (no external tooling), and the installer ships a precompiled runtime for every supported board — the Upload runtime button works on a fresh machine with nothing else installed.
Fixes for installed-editor paths (Program Files is read-only) and for user profiles with diacritics in the name.

2026.08.17

First public installer: device-bound runtime licensing (the license follows the panel, not the editor), signed builds and a built-in update check.
