 * Core: Scopesession loading now uses multithreaded IO for significant performance gains especially when many channels and deep history are involved
 * Drivers: Added support for many more PicoScope models
 * Drivers: ThunderScope now overlaps socket IO and GPU processing of waveforms giving a significant increase in WFM/s rate
-* Filters: Added GPU acceleration for several filters including CDR PLL (7.5x speedup), 100baseTX (10x speedup), DDJ (16x speedup), eye pattern (25x speedup), histogram (12x speedup), TIE (5.3x speedup) and more (https://github.com/ngscopeclient/scopehal/issues/977).
+* Filters: Added GPU acceleration for several filters (https://github.com/ngscopeclient/scopehal/issues/977) including:
+  * AC Couple (10x speedup)
+  * CDR PLL (7.5x speedup)
+  * DDJ (16x speedup)
+  * Ethernet - 100baseTX (10x speedup)
+  * Eye pattern (25x speedup)
+  * Histogram (12x speedup)
+  * TIE (5.3x speedup)
 * Filters: CDR PLL now outputs the input signal sampled by the recovered clock in a second data stream (https://github.com/ngscopeclient/scopehal/issues/991)
 * Filters: FFT now works with arbitrary length input rather than truncating to next lowest power of two
 * Filters: Peak detector for FFT etc now does quadratic interpolation for sub-sample peak fitting
