This list starts with Version 0.53 since there were just too many
changes before. Not every version number is listed.
2.2 -> 2.3
2.2 -> 2.3 (December 2019)
main changes:
This release contains multiple fixes that have been made over nearly two years. Few additional
features have been added in this release, it predominatly has bug fixes for both physics and in
general. The features that have been added are still experimental and typically revolve around
mode-matching sensing/actuation, so are not suggested to be used currently.
syntax change:
o Refractive index warning at 4 now instead of 3 due to Silicon test mass modelling being more frequent
......@@ -21,6 +25,8 @@ added features:
o Astigmatic lenses:
lens** name fx fy node1 node2
lens*** name px py node1 node2
fx,fy,px,py also work as xaxis and put targets. These astigmatic parameters are only available
when you define the component with lens** or lens*** otherwise you can only tune with f and p.
o Overall amplitude of the map applied to a mirror can be changed with the `map_amp` attribute.
Added so that you can lock drag some a map from off to on from some known DC operating point.

conf l1 z_fsig_self_coupling 1
This removes the phase modulation like term that appears with waist position modulation.
o Xaxis stepping using Kahan summation now to ensure we hit zero more accurately
o Signal matrix calculations are not performed when computing the DC lock point now.
This means that signal matrix calculations cannot be used for computing the DC operating point
anymore, however this shouldn't really have been a use case anyway.
bug fixes:
o Minus sign fixes have been applied for suspended components: mirrors and beamsplitters
......@@ -80,6 +92,16 @@ bug fixes:
which leads to the wrong cavity parameters being show for odd-number mirror cavities.
This doesn't affect any actual calculation of optical fields amplitudes, just detector
and trace outputs.
o Windows named pipe correctly closed, hopefully stops Windows pykat connection being dropped
when too many connections are left open.
o Rebuild flag for knm calculations was getting overwritten for m and bs when using x2axis, this
is fixed now.
o Laser frequency modulation amplitude factor is now fixed, erroneous 4pi factor
o segfault when using slink fixed
o modulator phase fsig lower sideband conjugate missing, now included
o dbs component now checks refractive index differences stopping weird beam parameter
