4.0.9-beta

Release Notes - Version 4.0.9-beta

Features

• Added in-app purchase of Radiens Pro and Pro+ — pick a plan, confirm, and get the invoice link directly in the app instead of contacting sales
• Added spike sorter settings for neighbor search radius and maximum neighbors per site
• Updated the headstage library to match the current production set, including the XDAQ V1.1 and V2 headstages
• The radiens command-line tool now ships alongside the application

Fixes

• Newly purchased features now unlock immediately instead of requiring an application restart
• Failed upgrades now explain what went wrong instead of showing a generic error
• Corrected the noise floor measurement used for spike detection, so missed spikes no longer raise the threshold that hid them; noise and SNR values are now consistent everywhere they are reported
• Fixed the signal group losing its filter settings after rescanning ports, and removed disconnected ports from those settings
• Fixed detect-only offline sorts producing incorrect output
• Fixed a headstage that failed to load because of inconsistent capitalization in its name
• Fixed spike waveform data being misaligned when read back

4.0.8-beta

Release Notes - Version 4.0.8-beta

Features

• Made the headstage and probe pickers searchable — type to filter the catalog instead of scrolling a ~1000-option list, with matching on product name, catalog ID, and channel count
• Added favorites to the sensor pickers, saved locally so your most-used headstages and probes stay at the top of the list
• Added expandable product family groups to the sensor pickers, so related headstages and probes are grouped instead of listed flat
• Added color-coded segments and curated product names to headstage entries for easier identification
• Added compatibility warnings for specific sensor product families when selected
• Widened the sensor dropdown so long product names fit on one line, and added a hover tooltip showing the full name when a selection is cut off
• Removed the bundled Python runtime: filters are now designed natively, giving a smaller install, faster startup, and one less component that can fail to launch

Fixes

• Fixed filter accuracy at very low cutoff frequencies — steep filters near DC previously produced a distorted passband
• Fixed a crash when setting an invalid (non-finite) spike detection threshold
• Fixed crashes when requesting very short or single-sample data segments
• Fixed spectral toolbar buttons being cut off in narrow tabs
• Fixed arrow-key navigation in dropdowns unintentionally changing the selected DAC channel on the Raster, Sinaps Signal Metrics, and Spike Grid tabs
• Fixed changing the DAC channel from the Raster tab
• Hid the DAC highpass option for Gen 2 XSR chips, which do not support it
• Disabled clearing of individual DAC channels, which was not supported
• Removed a stray extra dropdown arrow in the Analog Out control
• Left-aligned the sensor picker dropdown, which previously extended past the field over the sidebar
• Gave dropdowns, menus, dialogs, and tooltips a consistent shadow and border so they stand out against the surfaces they open over
• Fixed tooltips not appearing on disabled, license-gated controls
• Fixed layout of monitor preset views when license-gated
• Removed an uninformative tooltip on the sensor warning icon

4.0.6-beta

Release Notes - Version 4.0.6-beta

Breaking Changes

• XDAQ Gen2 devices require a firmware update (build 2026-05-19 or later, API version "1") to work with this release
• Previously generated recording quality (.kpi) files are discarded and regenerated automatically the first time a recording is opened
• The original high-density snapshot API is deprecated in favor of a new version; the head-relative snapshot call has been removed

Features

• Added a branded launch screen at startup instead of a blank window while your session loads
• Sign-in, sign-up, and verification buttons now show progress while a request is in flight, and can no longer be double-submitted
• The Spectral tab now backfills recent history on every reset — initial open, channel group, configuration, frequency range, or DSP changes — so the plot repopulates immediately instead of going blank for several seconds
• Added a new snapshot request that returns deterministic results and can optionally apply DSP filtering
• Batch spectral requests can now apply the same DSP filtering used in the display
• Added a new recording quality metric reporting mean peak-to-peak amplitude across detected events, which better represents channels whose positive peaks exceed their troughs
• Spectral requests now warn when the requested frequency or time range falls outside what the data supports, instead of silently clamping
• Sign-up now moves straight to the application after verification

Fixes

• Fixed common average referencing removing only part of the common signal whenever a filter chain covered a subset of channels — including every multi-port recording and any recording with a channel selection. Spike sorting and quality metrics could previously operate on differently referenced data for the same recording
• Fixed the Windows installer silently failing to install the Visual C++ runtime, and added an error message if the install cannot be launched
• Fixed spectral power values from Welch estimates being scaled incorrectly
• Fixed spectral results overflowing to infinity on the dB scale
• Fixed the Spectral tab replaying the entire stopped interval when streaming was resumed, instead of picking up live
• Removed the spurious error notification that appeared every time spectral streaming started in Allego
• Improved Spectral tab responsiveness during live streaming
• Fixed XDAQ Gen2 headstages being detected on the first scan and disappearing on every scan afterward
• Fixed manual TTL output not driving the pins on XDAQ Gen2 stim systems
• Fixed a data corruption issue in signal conversion that could produce incorrect values
• Fixed high-density snapshots ignoring the requested channel selection
• Fixed incorrect quality metrics for recordings with a non-zero start time, and excluded data blocks that fall outside the requested range
• Fixed a stale sensor label carrying over between ports in the channel summary
• Fixed crashes on unsupported signal types and stale channel configurations, which now report an error instead
• Fixed a crash when accessing an XDAQ Gen2 device that had been disconnected
• Fixed license information occasionally failing to load immediately after signing in
• Fixed multi-device sign-in detection not running on initial load
• Renamed the "Max-Min Difference" quality metric to "Peak-to-Peak"
• Changed the initial sign-up page heading from "Confirm Password" to "Create Password"
• Each authentication page now focuses its first field automatically
• Improved wording of the analytics opt-in
• Removed the unlicensed landing page; all accounts now start with a Standard license

4.0.4-beta

Release Notes - Version 4.0.4-beta

Features

• Rebuilt the Signal Processing tab around a new Filter Builder, with hardware filters now edited directly from the Signal Path instead of the configuration form
• Replaced the metrics Accumulated/Stream toggle with a lookback time-window control (default 1 second), and metrics now appear from the first packet instead of waiting for a full window of data
• Signal metrics now indicate whether a min/max reading is an envelope or an exact measurement, and trimmed the metric list to the 14 that carry distinct information
• Reduced spike detection and metrics computation overhead for large channel counts
• Configuration tabs now dock into the new window's tab set when floated

Fixes

• Fixed channels that appear after startup never detecting spikes — they reported zero events indistinguishably from a quiet channel
• Fixed reopened recordings measuring thresholds against a default noise floor instead of the noise floor saved with the recording
• Fixed channels with no data being painted as maximum red on the site color map; they now render as no-data
• Fixed spurious "out of range" errors when requesting metrics for a valid time range
• Fixed the signal metrics table and its handling of missing values
• Fixed recording wall-clock times rendering incorrectly when absent
• Fixed an occasional crash when subsampling a channel with no detected spikes
• Signal path and filter editing is now disabled rather than hidden while recording
• Removed the separate spike-sorter filter choice from the metrics configuration; detection, metrics, and the displayed traces now all use the same signal

4.0.4-alpha.2

Release Notes - Version 4.0.4-alpha.2
