2013/07/18 v0.99.26 - A bug in confmgr.c caused errors when reading strings from the configuration (thanks Graham Inggs) 2013/01/09 v0.99.25 - A rather important bug infiltrated when changeing the configuration system. Though I carefully prepared the default values for the vector map, I entered them in hex which them caused a white chart. If you had/have this problem, the easiest way out is to use this new version, but first deleting the previous configuration file (in your home directory .gnome2/linsmith) - To encourage the use of the vector chart anyway, it is now the default for new installs. 2012/12/04 v0.99.24 - Print bug correct (Segfault on second call to print). (Thanks for reporting, Clyde!) - Cleanups in the configuration load/save functions 2011/03/21 v0.99.22 - Change papersize_combo to combobox, and load the list from the available papersizes. - Adapted confmgr to accept char * from comboboxes. - Moving down elements caused a segfault, because of wrongly g_free'ing an iter. (Thanks clydes!) - Moving elements up implemented. - A crash in the configuration dialog fixed, which made it impossible to save the SWR circle color. (Thanks clydes!) - Converted the strange negative default values for the color definitions to their (easier to understand?) hex values. - The 'standard cable' code mostly re-written, and a few more cable types added. 2011/03/20 v0.99.21 - Removed the (deprecated) gnomeprint depency. Now the complete print route relies on Pango/Cairo to generate the plot, and the GtkPrint interface to do the actual printing. (After some poking from Thomas Beierlein, from gentoo. Thanks) 2010/05/14 v0.99.20 - Slight improvements to the vector plot. - Better (?) default values for colors of plot. - Modified the confmgr to accept hex and octal values in the configuration file. 2009/05/08 v0.99.12 - Missing NULL in run_filedialog caused warnings when saving the log. In some cases it could cause segmentation faults too. Thanks to the guys at Fedora for notifying me! 2008/09/02 v0.99.11 - Swedish translation updated (Thanks Peter!) - Smaller bugs corrected which could cause a few problems if z0 was changed. (chart.c - Thanks for the indications, Anatoly!) 2008/08/22 v0.99.10 - The last s2p file's name is now saved in the configuration. Had forgotten that in the previous version. 2008/08/21 v0.99.9 - Added import of Touchstone(r) two-port files. Until now, only Version 1.0 files are correctly parsed, though completely (I hope) with all parameter types, and input formats. - Spanish translation has been updated. - Manual has been updated with this info. 2008/05/26 v0.99.7 - Dustin Vaselaar reports problems inputing loads. 'errno' is now cleared before each strtod call. 2008/04/25 v0.99.6 - Applied a patch to fix possible startup crash in case of missing background charts (provided by bernardb - thanks!) - Added a more complete syntax check on load input. Empty fields are not permitted anymore. Check is done on both the normal and noisebridge input pages. - Typo in preferences ('connectios') - Added import of impedances in CSV format - Added dialog to warn about existing loads when importing or loading new values. 2007/10/11 v0.99.5 - Changed the name of aux.c and aux.h to misc.c and misc.h, because when I tried to compile linSmith on Windoze, I found out that aux (no matter what the extension) is reserved by the operating system (DOS inheritance). - Changed the open/close file dialogs to the newer, and much improved filechooserdialog. - Experimentally added import for TouchstoneTM files (s2p format, incomplete)). - Moved calls to the open/save functions out of callbacks.c and to the corresponding files. 2007/01/03 v0.99.4 - Hans Nieuwenhuis reported an error in log.c which could cause crashes when generating a data log. Thanks! 2006/11/15 v0.99.3 - A few other potential char array traps removed. These are of less importance as the reserved space was more than enough to accomodate the strings. 2006/11/06 v0.99.2 - Thanks to Alexander to report a craching problem, and to the people at Ubuntu (Bernard) to pointing out the problem. Long font names caused this. I've replaced these (static) buffers by dynamically assigned ones. Please, distro people, I'd appreciate it if you advise me when you include linSmith in your package! I can provide a link to your package, and I can be prepared for specific problems! 2006/07/09 v0.99.1 - Added the vector-generated background map for the chart. - Modified configuration to allow for definition of the background color of the vector chart. - Corrected the font selection for the vector chart (use GtkFontButton). - Added a config parameter to set the initial size of the vector chart. - Optimized the chart generation by eliminating symmetric reactance circles from the table. - Modified the table into a proper .h and .c file. - Added zoom factors 2006/06/24 v0.9.8 - Version in component files is now the complete version in a single string. This should not raise any incompatibilities. - Updated es.po - Modified the Results page: Circuit impedance is now shown as either Z or Y depending on the Z/Y blocks inserted in the element list. This can be disabled (forced to impedance only) in Preferences. (This also applies to Results export file) - Separate resolutions settable for impedances and admittances. 2006/06/19 v0.9.7 - Corrected the 'live' display of the cursor values under the graph - they remained at 50 Ohm even after changing z0 (Thanks Anatoly! tarant941[at]m-lan.ru) 2006/04/10 v0.9.6 - Corrected the connecting arcs for 'to load' rotation. - Modified the load impedance input to select different input data sources and types. - Don't enable the 'New' or 'Update' buttons if the values are not valid (f != 0). - Noise bridge input works! Input in R and C, values are shown as R and X in the load table. 2006/04/06 v0.9.5 - Added a 'Clear' button to the load and element lists. - Replaced large 'Recalculate' button by a smaller version, and moved it to the left, to make space for the rotation list. - Added the Rotate list, to select rotation to generator or to load. Added the option to the preferences record. Note that though transmission lines already rotate correctly, the connecting line is still wrong. - Setting the Zo box on startup caused errors in the (not yet existing) log_list. Solved. - Minor bugfix in configuration window. Screen font name was not correctly saved and could cause execution problems. - After configuration, chart must be in non-logo mode, else an error message is produced when trying to update the SWR circle 2006/03/30 v0.9.4 - Chart also updates when loads are added or modified. - Infrequent bug detected in load management. Could be the problem while importing from remote? - Redefined (improved) quite a few routines in the load.c file. This caused a few bugs (which I hope, are resolved). Please report on any problems. 2006/03/22 v0.9.3 - Changed order of element definition: Select Series/parallel first, the actual component. Show only the possible components in each case. This causes quite a few changes in aux.c. - Error in setting the component buttons solved. - Changing Zo on the main window now has immediate effect. - (More or less) centralized the enabling the buttons on the element page. Hope this improves the usability. 2005/11/03 v0.9.2 - IMPORTANT: It seems there were some problems with the connecting impedance/admittance circles in the previous version. I hope this is now resolved! - Added another example and revised the data files. - Margarita7113
did some exceptional work, correcting the es-translation, adapting some makefiles, she even provided an icon and a man-page for linSmith! Thanks... - I've removed the doc-generation files entirely, only the final PDF is included. There were reports about low-quality fonts, and other issues which are not easily addressable in the automatic install procedure. - Corrected the 'Save results...' option permitting saving the numerical results to a file. 2005/10/17 v0.9.1 - Added filenames to the 'loads' and 'circuit' page, and an 'changed' flag to indicate the list has been modified. - Added 'Save results page' option in the 'Files' menu, to save the numerical results - Added a Swedish translation (Thanks to Peter Landgren peter.talken[at]telia.com!) 2005/05/15 v0.9.0a3 - An error in calculating parallel LC circuits sneaked into the code cleanup (corollary: never clean up code?) - The number of decimals in frequency is now settable in the configuration. - SWR circle immediately redraw after saving config. - Expanded the cable table, changed selection - Updated es.po, and partially de.po. My german is not too good I'm afraid. 2005/05/12 v0.9.0a2 - Value text for Z/Y component wasn't initialized. - On Lawrence's request, I changed the frequency resolution to 3 decimals - Update and New buttons were not activated reliably - solved - Main screen component editor showed uH, should be nH - corrected (again Lawrence...) 2005/04/02 v0.9.0a1 - Added parallel and series LC combination which were difficult to enter before. This caused a huge number of other changes - even in the circuit file data format. This new format isn't compatible! I wrote a small script in Tcl which can convert the old format (conv0809). - Changed the layout of the component input page - Changed the layout of the load input page - Much needed cleanup of callbacks.c - Changed the component scrollbars. They will now auto-return to center, if not held with the mouse, after 1 second. This makes it much easier and faster to experiment. - Modified the format of the component list to accomodate par/ser LC combinations. - I'm using the Omega sign to format the line info This could cause problems with some character sets if the symbol isn't defined. Please report if this doesn't work for you. - Save file paths at any save or load - Solved a bug which didn't show connections with stubs - Improved (more logical) component description - Solved a bug with 'updating' open/closed stubs - Found and solved a bug in saving transmission line components. - Updated predefined cable selection to the new system. 2004/12/23 v0.8.4 - Fixed a (double) bug in the zoom procedure, particularly visible when zooming out (thanks to Lawrence Glaister ve7it[at]shaw.ca for reporting this). - The configuration interface is present to set up the remote control. It is _not_ enabled yet! 2004/12/09 v0.8.3 - Added a German translation (Thanks to Georg Baum, Georg.Baum[at]post.rwth-aachen.de) - Please check the NEWS file! 2004/09/10 v0.8.2 - Added the TODO list to the distro... Maybe someone helps out? 2004/08/17 v0.8.1 - Added #include of getopt.h to main.c. Though not necessary on my machine, some configurations do need it, and, really, it should be there. (Thanks Sid Boyce, G3VBV, sboyce[at]blueyonder.co.uk) - One of the 'todo-list' items implemented: the effect of changing the value scrollbars is now immediately visible on the chart. This is really quite spectacular. (Thanks Lawrence Glaister VE7IT, for reminding me) 2004/08/03 v0.8.0 - Adapted the config files and the config screen to be able to select properties for the dynamic on-screen background. (Though the dynamic chart is not enabled yet) - Enabled the zoom buttons (can now zoom from 0.1 to 10x) 2004/07/24 v0.7.6 - Added Chinese translation (Thanks to Once, once_shuiqing[at]hit.edu.cn) - Added Spanish translation - Once also reported a bug when clicking 'Modify' on the loads page (corrected) 2004/07/18 v0.7.5 - En error in the configuration files causes compilation errors on some systems. This should fix it. Please update. 2004/07/17 v0.7.4 - More suggestions from Georg (thanks!): - Size of up/down buttons in Circuit (done) - Size of ok/cancel buttons on config dialog (done) - Moved 'print'-checkbutton to a File-menu item - Confirmation before overwriting previous export - Font picker added to select. The font selection mechanism is too picky (sic) to just use a entry widget. 2004/07/15 v0.7.3 - Thanks to Georg Baum for the testing & suggestions. - Change the initial (logo) pixmap path in chart.c to include PACKAGE_DATA_DIR - Change the default pixmap path in global.c to include PACKAGE_DATA_DIR - Set the correct scale/offsets for the chart included - Included a few examples to be installed in /linsmith - Now actually included the logo pixmap 2004/06/26 v0.7.2 - Added SWR circle and G=1 circle, and the configs to match. Checked both on-screen and PS output. - Added connecting linse for Z/Y switches. Tested on most combinations. - Enabled the transformer (no connecting lines... are they advisable?) - Changed the screen bg chart properties to double (from int), as sometimes fractional corrections seem to be appropiate. 2004/06/22 v0.7.1 - Added the Z/Y element to switch between impedances and admittances. Modified many functions to adjust for this trick. - Apologized to the gnome-print group for the accusation... The fault was mine. 2004/06/10 v0.6.1 - Got the PS output working. Mind - there is still a problem with gnomeprint - the first string printed with a global scaling active is printed in the wrong size. (Added a dummy label to prevent this) 2004/05/22 v0.3.1 - Start keeping a changelog - Call calc_el_impedance only when needed, i.e. not when adding a series line.
