Recent changes and bug fixes

• Version 9.72 fixes a bug that mis-handled ST scenarios if there was only one non-ST scenario in the project, and adds change in K as a variable that can be modified in ST.
• Version 9.71 fixes a missing label and fixes a bug that could cause a crash when the Translocation special option was chosen.
• Version 9.70 replaces a not very reliable (but MS standard) random number generator that would often have caused less than random results when a seeded random number generator was included in a function of demographic rates.
• Version 9.61 adds a new variable, PARITY (= the number of offspring produced by an individual, whether still living or not), to those variables available for use in functions.
• Version 9.60 fixes a significant bug that caused an entered Dispersal Modifer Function to sometimes not be used.
• Version 9.59 fixes a few obscure bugs (not ones that most people would encounter) that caused incorrect tallies of numbers of males (WW) and females (XX) in other populations when these variables were used in functions, and that sometimes lost Notes that were entered if they were not saved immediately. This version also includes some minor improvements, such as retention of Graphs and Graph Options when that screen is exited and then you return, and a change in the way that mortality rates are listed in the Sensitivity Testing Set-up (so that, for example, the variable for mortality between age 0 and 1 is now displayed as FemaleMortality_Pop1_Age0 rather than as ... _Age1).
• Version 9.58 fixes a bug in the use of IIS1, IIS2, etc. for Individual State variables in functions. It also fixes a problem that caused the screen shots not to appear when Help was invoked.
• Version 9.57 fixes a handful of problems that would have caused some data not to be displayed on graphs, and could have caused erroneous SDs of times to extinction if a Scenario was run, and then later resumed to add iterations. It also makes additional genetic data available to other programs that might be linked in a meta-model.
• Version 9.561 fixes a bug that would sometimes cause the y-axis of a graph to be scaled poorly.
• Version 9.56 (and the non-distributed versions between 9.51 and 9.56) fixes some obscure bugs (such as could have occurred if you used individual state variables within functions, and had supplementation), adds an option for screen text to be in Portuguese (in addition to Spanish and English as options), includes some enhancements to the internal coding to improve speed, adds some variables to the ones available for use in functions, and adds the ability to use functions for the numbers of animals to be harvested or supplemented.
• Version 9.51 added the ability to plot probability of extinction (in addition to probability of persistence), fixes a bug that caused problems if scenarios were added or deleted after Sensitivity Test analyses were created, and fixes a bug that would report incorrect probabilities of extinction if new iterations were added to a scenario with the 'Resume' command.
• Version 9.503 fixes a bug that could have caused the simulated populations to crash to 0 each iteration when EV was set to a very small, non-zero value.
• Version 9.50 implemented an automated sensitivity testing module, and a genetic management option.
• Version 9.42 fixes a problem with an incompatibility between versions of the Graphics Server that is used by Vortex. If you have already installed Vortex 9.41 on your system, you may need to do some manual changes before you can get it or any later version to work correctly. If you installed version 9.41 and are having problems with graphs, contact help@Vortex9.org and we will give you further instructions.
• Version 9.41 fixes some more bugs, including some related to saving notes, and implements a few more options.
• Version 9.33 fixes some minor bugs, added back in Stop and Pause buttons, and handles abnormal progam terminations better
• Version 9.31 fixes a bug that caused problems for loading some input files from previous versions, and enables Vortex to work with a greater variety of Regional Language/Data settings
• Version 9.30 made a number of changes, including:
• some changes to the lay-out of the input screen for labels and state variables
• capability to create up to 10 Population State Variables for use in functions
• change of data transfer between Vortex and other programs to an xml file, thereby requiring installation of xml capabilities on your system if you intend to use Outbreak or other meta-model links
• simplification of the way Notes are entered for input fields
• ability to prevent matings that would result in inbreeding
• addition of optional labels for catastrophes
• removal of the buttons to Stop and Pause simulations (which did not work correctly on some systems)
• a number of other small fixes to screen formats and minor problems
• Version 9.23 fixes a bug that could cause the simulation to stop if an extinct population is recolonized with 1 supplemented individual
• Version 9.22 fixes various bugs that could have caused problems for some specific cases (e.g., some cases with very large populations, and some cases using functions for demographic rates) and fixes a few problems that could cause the program to use much more memory than was really needed. Also, a change was made to limit the maximum population size to 5000 when using the non-lethals model of inbreeding depression. Otherwise, the program would likely use the hard disk to do inbreeding calculations, leading to unacceptably slow analyses.
• Version 9.21 fixes a problem in version 9.20 that could set initial N to 0 for all populations after the first one.
• Version 9.20 fixes some bugs in the saving of Notes and otherwise. It also includes a slightly improved lay-out of input screens for Dispersal.
• Version 9.17 uses InternetExplorer to display Help in a way that is more consistently stable across versions of Windows.
• Between version 9.16 and 9.161, a bug was fixed that would cause the program to tie up all RAM (and then start causing erratic behavior of the display) when multiple scenarios were run on computers running Win95 or Win98.
