----------------------------
9/21/07
- Released version 3.2.
9/17/07
- Added option to `cdf2matp.m` to specify output case file version.
9/7/07
- Fixed bug in `pfsoln.m` which caused incorrect value for `Qg` when
`Qmin == Qmax` for all generators at a bus in power flow solution.
- Added 5 larger scale (> 2000 bus) cases for Polish system.
*Thanks to Roman Korab <roman.korabpolsl.pl>.*
- Modified default OPF algorithm selection to use PDIPMOPF
if available and MINOPF is not. Order of precedence is now
500, 540, 520, 100/200.
7/6/07
- Added ability in `opf.m` and `fmincopf.m` to specify initial value
and bounds on user variables via new input arguments `z0`, `zl`, `zh`.
6/22/07
- **INCOMPATIBLE CHANGE:** Name of option 24 in mpoption change from
`OPF_P_LINE_LIM` to `OPF_FLOW_LIM`.
- Added option to use current magnitude instead of apparent power
for line flow limits. Set `OPF_FLOW_LIM` to 2.
6/21/07
- **INCOMPATIBLE CHANGE:** Changed the sign convention used for
phase shifters to be consistent with PTI, PowerWorld, PSAT, etc.
E.g. A phase shift of 10 deg now means the voltage at the "to"
end is delayed by 10 degrees.
6/15/07
- Added `t_auction_pdipm.m` and renamed `t_auction.m` to
`t_auction_minopf.m`.
6/8/07
- Updated `have_fcn.m` to check for appropriate minimum versions of
MATLAB, for TSPOPF.
6/7/07
- Modified `printpf.m` to correctly detect binding line limits when
a limit of 0 is taken to mean unconstrained.
- Fixed bugs in handling of multipliers for general PQ capability
curves in `fmincopf.m` (also in `mopf.m` and `tspopf.m`).
- Refactored `t_opf.m` into separate files for each solver.
- Modified `opf.m`, `mpoption.m`, `mpver.m`, `have_fcn.m` to include
support for TSPOPF, a new optional package of OPF solvers.
9/29/06
- Added check to `runpf.m` for case where all gens hit Q limits when
`ENFORCE_Q_LIMS` is enabled.
