major changes such as a substantial reorganization of the
documentation into a User Guide and Reference Manual, more
consistent and complete docstrings, and support for referencing
signals and subsystems by name as well as by index. Phase plane
plots now use matplotlib’s streamplot for better visuals. New
functions include combine_tf and split_tf for MIMO/SISO
conversion and disk_margins for stability analysis. Additional
improvements include consistent keyword usage, expanded LTI
system methods for plotting and responses, better error
messages, and legacy aliases to maintain backward
compatibility.
* This version of python-control requires Python 3.10 or higher,
NumPy 1.23 or higher (2.x recommended), and SciPy 1.8 or
higher.

* This release includes numerous bug fixes and improvements, with major changes such as a substantial reorganization of the documentation into a User Guide and Reference Manual, more consistent and complete docstrings, and support for referencing signals and subsystems by name as well as by index. Phase plane plots now use matplotlib’s streamplot for better visuals. New functions include combine_tf and split_tf for MIMO/SISO conversion and disk_margins for stability analysis. Additional improvements include consistent keyword usage, expanded LTI system methods for plotting and responses, better error messages, and legacy aliases to maintain backward compatibility.
* This version of python-control requires Python 3.10 or higher, NumPy 1.23 or higher (2.x recommended), and SciPy 1.8 or higher.
## New classes, functions, and methods
* find_operating_point: this function replaces (with a legacy
alias) the find_eqpt function and now returns an
OperatingPoint object containing the information about the
operating point.
* combine_tf and split_tf: these two new functions allow you to
create an MIMO transfer function from SISO transfer functions
and vice versa.
* create_statefbk_iosystem now allows the creation of state
feedback controllers using a “reference gain” pattern (u =
k_\text{f}\, r - K x) in addition to the default “trajectory
generation” pattern (u = u_\text{d} - K(x - x_\text{d})).
* disk_margins: compute disk-based stability margins for SISO
and MIMO systems.
* model_reduction: allow specific states, inputs, or outputs to
be either eliminated or retained.
* place_acker: renamed version of acker (which is still
accessible via an alias).
## Bug fixes
* phase_plane_plot: fixed a bug in which the return value was
returning a sublist of lines rather than just a list of lines
in cplt.lines.
* Processing of the timebase parameter (dt) for I/O systems is
now handled uniformly across all I/O system factory functions.
This affected the zpk function, which was defaulting to a
discrete time system to have timebase None instead of 0.
* Multiplying (*), adding (+), or subtracting (-) a constant

* Version 0.9.1 is a minor release that includes new
functionality for discrete time systems (dlqr, dlqe, drss),
flat systems (optimization and constraints), a new time
response data class, and many individual improvements and bug
fixes.
**New features:**
* Add optimization to flat systems trajectory generation (#569 by
murrayrm)
* Return a discrete time system with drss() (#589 by bnavigator)
* A first implementation of the singular value plot (#593 by
forgi86)

step_info (#600 by bnavigator)
* New time response data class (#649 by murrayrm)
* Check for unused subsystem signals in InterconnectedSystem

* New PID design function built on sisotool (#662 by
sawyerbfuller)
* Modify discrete-time contour for Nyquist plots to indent around
poles (#668 by sawyerbfuller)
* Additional I/O system type conversions (#672 by murrayrm)
* Remove Python 2.7 support and leverage @ operator (#679 by
bnavigator)

**Improvements, bug fixes:**
* Change step_info undershoot percentage calculation (#590 by
juanodecc)

* Version 0.9.0 of the Python Control Toolbox
(python-control) contains a number of enhanced features
and changes to functions. Some of these changes may
require modifications to existing user code and, in
addition, some default settings have changed that may
affect the appearance of plots or operation of certain
functions.
* Significant new additions including improvements in the
I/O systems modules that allow automatic interconnection
of signals having the same name (via the interconnect
function), generation and plotting of describing functions
for closed loop systems with static nonlinearities, and a
new optimal control module that allows basic computation
of optimal controls (including model predictive
controllers). Some of the changes that may break use code
include the deprecation of the NumPy matrix type (2D NumPy
arrays are used instead), changes in the return value for
Nyquist plots (now returns number of encirclements rather
than the frequency response), switching the default
timebase of systems to be 0 rather than None (no
timebase), and changes in the processing of return values
for time and frequency responses (to make them more
consistent). In many cases, the earlier behavior can be
restored by calling use_legacy_defaults('0.8.4').
New Features:
* Optimal control module, including rudimentary MPC
control (#549 by murrayrm)
* Describing functions plots (#521 by murrayrm)
* MIMO impulse and step response (#514 by murrayrm)
