No longer rely upon DABS callbacks during data acquisition, but poll instead. All internally-generated triggers are now themselves triggered off a common "master" trigger on PFI8. |
| 0.779 | April 14, 2015 | Fixed bug where couldn't test pulse after acquiring data. |
| 0.78 | April 15, 2015 | Data files for continuous recordings now use the same file naming scheme as trial-based recordings. Fixed bug with fast protocols not getting cleared when you click that button. Added a very simple example user function .m file. |

Added example user hook classes that implement treadmill- and VR-triggered spike rasters. Many other small tweaks and improvements. Note that version 0.8 will not generally read protocol files from earlier versions. |

Test pulser now shows resistance in units tailored to the scale of the resistance value. Protocol and user settings file formats were not changed from release 0.8. |
| 0.802 | June 12, 2015 | Fixed error on MDF load under R2013b. Added ability to turn on/off scope grids. Protocol and user settings files from release 0.8+ will still work with this release. |
| 0.803 | June 29, 2015 | Fixed bug in ws.loadDataFile() that made it error if any channels were not active. Protocol and user settings files from release 0.8+ will still work with this release. |

| 0.805 | July 23, 2015 | Fixed bug that made it impossible to record if a user class was in use. |
| 0.9-b-1 | Oct 12, 2015 | (Beta release) Major redesign of WaveSurfer to support low-latency (< 5 ms) real-time feedback loops. WaveSurfer now spawns two additional Matlab processes when you lauch it: one to aquire data and run real-time feedback loop code, and another to ensure that the sweep-based output buffer is refilled properly. Also some streamlining of the triggering settings, and changes in terminology (e.g. "trials" are now sweeps, an "experiment" is now a run). Note that this is a beta release, so is likely somewhat buggier than a regular release.Fixed bug that made it impossible to record if a user class was in use. |

| 0.901 | Jan 7, 2016 | Added support for DAQmx 15.1.x. Fixed bug in error dialog message if the installed version of DAQmx is not supported by WaveSurfer. |
| 0.91 | Feb 12, 2016 | All things previously-settable in machine data files (MDFs) are now settable in the normal WaveSurfer user interface. This means users no longer need to create an MDF before using WaveSurfer to acquire data. (Protocol files for previous versions of WS will not work with this version.) |
| 0.912 | Mar 1, 2016 | Fixed bug in README. |
| 0.913 | Mar 2, 2016 | Fixed bug which resulted in actual sampling rate being slightly different from nominal sampling rate for sampling rates (in Hz) that do not evenly divide 100 MHz. |
| 0.914 | Mar 15, 2016 | Fixed bug where data was saved without scaling coefficients. Added code to ws.loadDataFile() convert nominal sampling rate for pre-0.913 data files to correct sampling rate. Added code to ws.loadDataFile() to error if asked to return floating-point (scaled) data when the data file lacks scaling coefficients, as a safeguard. |

to automatically append device scaling information to .h5 data
files that currently lack it. |

| 0.9192 | Jun 3, 2016 | Fixed bug with adding calibration coefficients to old files taken with devices with more than 16 (single-ended) AI terminals. |
| 0.92 | Jun 27, 2016 | Added support for more recent versions of DAQmx. Can now duplicate stimuli, maps, sequences. Better support for old protocol files. Fixed bug causing errors on stimulus deletion in some cases. Can now write calibration data to disk, use that file to add calibration to data files. Fixed bug with electrode AO scaling. Added debugging mode which shows satellite windows running in full-JVM Matlab sessions. Added checkbox to optionally turn off electrode gain reading before a run or a test pulse. Added tooltips to fast protocol buttons. Improved speed of protocol file loading. Improvements to display and data scaling speed, especially for long sweeps. Fixed bug where stopping a run at an unlucky moment would put WS into a weird, unusable state. |

| 0.941 | Oct 14, 2016 | Run will now continue past end of acquisition if stimulation is ongoing. Also fixed hangs in some situations. |
| 0.942 | Jan 11, 2017 | User classes now print debug info to terminal. Updated and streamlined Bias user code. Also fixed bug with map durations loaded from protocol files. Added fix for MultiClamp 700A support provided by Niraj Desai. |
