Breaking Changes

ASCII display formatting for all analyzers has changed. Now, non-displayable ASCII characters will be displayed as their hex escape sequence, instead of falling back to base 10 display. For example, the character 0x1C, which is not displayable, previously would be shown as '28', but now will be shown as x1C. This affects all protocol decoders and their export files when the ASCII display radix is selected. We also fixed the COMMA problem, it will now be shown as , in the application, however in exports it will still be replaced with COMMA until we eventually replace the protocol export system with one that is CSV safe.

New user feedback dialog - Draw on screen to suggest an idea or select a region to mark a bug

Improvement

data table infrastructure - Elasticsearch was a constant pain, mainly for Windows users. We replaced it with a faster and more stable DB (RocksDB). Cmd/ctrl+click on a graph result was removed temporarily. The data table currently supports only Async Serial, I2C and SPI. We'll add the rest of the analyzers soon.
Terminal - Faster and lighter (CPU wise) streaming of analyzer results. Async serial, SPI and I2C output looks great now :)
Digital trigger performance improved significantly and we can now keep up with most 10MHz signals
Analyzers are now 5-10X faster - we can keep up with most 10MHz signals
Digital edges snapping threshold was reduced to support dense data
App size was reduced by half (!)

Bug fixes

High-level analyzers - restore position and name correctly, when launching the app, loading a file or restarting a capture
Hard crash in analyzers was fixed
Analyzers - keep settings correctly between runs
Data management - Redux was replaced with MobX to improve app stability and performance

2.2.8 is a small follow up release after the big 2.2.7 release from last week. It mainly focuses on exception handling and memory management. The app now properly clears old memory when recording in looping mode, and it deletes sessions on a background thread to keep the UI responsive when restarting captures or closing tabs.

Bug Fixes

now properly delete memory when the capture buffer gets full.
moved session deletion to a new thread, so it doesn’t block the UI.
changed most USB error handling from hard crashing to an error notification.

TLDR;

2.2.7 brings dramatic performance improvements to digital capture processing and digital rendering! Our aim was to get the software to run smoothly when recording digital signals near the limit of the devices’ performance. Digital data processing is now 10x faster, meaning fewer “backlogged” captures!

Reminder: releases now include a new interface for writing high-level protocol decoders in Python. Check out the documentation here: github.com/saleae/logic2-examples

Bug Fixes:

Timing markers now snap to digital transitions again
saved calibration files are now loaded properly when offline
analyzer export now respects the currently selected display radix, instead of always exportin ASCII.
Custom protocol analyzers: if no results are added GenerateFrameTabularText, the frame is now hidden from the protocol results list view
Traces color now update immediately on change

Behind the scenes:

detailed performance instrumentation
significantly improved UI performance in live mode (5-10x)
dramatically improved processing performance of digital data (10x)
dramatically improved rendering performance of digital data (3x)
migrated analyzer management to a better state management system
refactored processing state updates from the data processing system

Features:

Custom protocol analyzers that have a “FilePath” or “FolderPath” TextSetting now have UI to select files or folders
press Ctrl+0 to reset text zoom (ctrl +/- zooms text size)
Cmd/ctrl+click on a decoded protocol result opens the analyzer sidebar tab and scrolls to that result
