Release Version Notes for the VSG60/200 Programming Interface

Support contact: support@signalhound.com

- Version 1.2.3 (8/14/2026)
* Support for AArch64 and MacOS. See README. 
 - Two new builds for Nvidia Jetson Orin AGX (Ubuntu) and MacOS (M4).
* Bug fix: External triggers were not working at high sample rates combined with partial I/Q imbalance corrections.

- Version 1.2.2 (3/25/2026)
* Fixed crash associated with using partial I/Q imbalance corrections.

- Version 1.2.1 (3/19/2026)
* Removed assertions.

- Version 1.2.0 (2/19/2026)
* Official support for the VSG200.

- Version 1.1.1 (10/9/2025)
* Added vsgSetImbalanceCorrectionMode function. 
  This function controls the I/Q imbalance correction algorithm.
  Can choose a new algorithm which trades worse imbalance for lower CPU usage.

- Version 1.1.0 (10/3/2025)
* Internal build, support for additional VCO adjustments.

- Version 1.0.8
* Internal build.
* Real-time phase noise impairment support.

- Version 1.0.7 
* Internal build.

- Version 1.0.6 (7/15/2021)
* API will now handle frequency hopping applications better when very small dwell times are used
  at each frequency. API will now limit the number of outstanding frequency changes that can be 
  queued and will block when this number has been reached. 

- Version 1.0.5 (7/29/2020)
* Removed debugging print messages to stdout.

- Version 1.0.4 (4/21/2020)
* Bug fix: Updating the sample rate in certain configurations would cause a residual frequency error. This has been resolved.

- Version 1.0.3 (1/6/2020)
* Support for Ubuntu 18.04 (x64)

- Version 1.0.2 (9/16/2019)
