There has been a long standing (since the beginning of the project?)
issue with sharing schematics between projects. It has been somewhat
supported for complex hierarchies (a sheet shared multiple times in a
single design) but it has not been well supported for simple hierarchies
(the symbol references cannot be changed in the shared schematic). This
issue has been resolved by moving all of the symbol instance sheet paths
from the symbol definitions in the all of the project files and save all
symbol path instances in the root sheet. This ensures that orphaned
symbol instance paths do not accumulate in shared schematic files and
that designs that reuse schematic in simple hierarchies can how have
different references. It also allows the root schematic from one project
to be uses as a sub-sheet in another project.
When legacy schematics are loaded, all sheet and symbol UUIDs are
converted from time stamps to true UUIDs. This is done to ensure there
are no sheet path instance clashes between projects. That being said,
there are no checks for this. It is assumed that the probability of
UUID clashes is so low that it doesn't make sense to test for them.
This is a very large and potentially disruptive change so this will be an
unusually long and detailed commit message.
The new file formats are now the default in both the schematic and symbol
library editors. Existing symbol libraries will be saved in their current
format until new features are added to library symbols. Once this happens,
both the legacy schematic and symbol file formats will be no longer be
savable and existing libraries will have to be converted. Saving to the
legacy file formats is still available for round robin testing and should
not be used for normal editing.
When loading the legacy schematic file, it is imperative that the schematic
library symbols are rescued and/or remapped to valid library identifiers.
Otherwise, there will be no way to link to the original library symbol and
the user will be required manually set the library identifier. The cached
symbol will be saved in the schematic file so the last library symbol in
the cache will still be used but there will be no way to update it from the
original library.
The next save after loading a legacy schematic file will be converted to
the s-expression file format. Schematics with hierarchical sheets will
automatically have all sheet file name extensions changed to .kicad_sym
and saved to the new format as well.
Appending schematics requires that the schematic to append has already been
converted to the new file format. This is required to ensure that library
symbols are guaranteed to be valid for the appended schematic.
The schematic symbol library symbol link resolution has been moved out of
the SCH_COMPONENT object and move into the SCH_SCREEN object that owns the
symbol. This was done to ensure that there is a single place where the
library symbol links get resolved rather than the dozen or so different
code paths that previously existed. It also removes the necessity of the
SCH_COMPONENT object of requiring any knowledge of the symbol library table
and/or the cache library.
When opening an s-expression schematic, the legacy cache library is not
loaded so any library symbols not rescued cannot be loaded. Broken library
symbol links will have to be manually resolved by adding the cache library
to the symbol library table and changing the links in the schematic symbol.
Now that the library symbols are embedded in the schematic file, the
SCH_SCREEN object maintains the list of library symbols for the schematic
automatically. No external manipulation of this library cache should ever
occur.
ADDED: S-expression schematic and symbol library file formats.
Keeping a pointer to the actual file history inside a special
file history menu led to many cases of use after free crashes,
so instead rework the actual file history to add the menu
items.

CHANGED: Settings are now stored in versioned sub-directories
ADDED: First-run dialog for migrating settings from a previous version
CHANGED: Settings are now stored as JSON files instead of wxConfig-style INI files
CHANGED: Color settings are now all stored in a separate settings file
CHANGED: The symbol editor and footprint editor now have their own settings files
CHANGED: Color settings are no longer exposed through BOARD object
CHANGED: Page layout editor now uses Eeschema's color scheme
Settings are now managed through a central SETTINGS_MANAGER held by PGM_BASE.
Existing settings will be migrated from the wxConfig format on first run of each application.
Per-application settings are now stored in one class for each application.
This also removes vector cover types which do nothing except obfuscate
the underlying implementation.
Mainly changes SCH_SHEET_PINS and CONFIG_PARAM_ARRAY (which will soon
be replaced by Jon's new stuff).
This moves EESchema DLIST structures to rtree. These changes are more
fundamental than the pcbnew changes from 9163ac543888c01d11d1877d7c1
and 961b22d60 as eeschema operations were more dependent on passing
drawing list references around with SCH_ITEM* objects.
and switch to the paren sheet from the context menu.
Mainly, change the way the dialog is managed from the sch_edit_frame:
the pointer to find the created dialog is replaced by a call to wxWidows::FindWindowByName().
Using a pointer set and cleared by events is a recipe for crashes.
ADD: User can now decide to keep the hierarchy navigator open while working
on a schematic.
This behavior can be configured in eeschema->preferences->eeschema->Editing options.
Create an IsContentModified() function in each frame
that provides if the content has been modified, and
use that instead of always copying the checks.
ADDED: a config option to select (when clicking on a pin) the parent symbol
or only the pin.
Previously, when cliking on a pin, the parent symbol was selected.
Allowing the pin selection is mandatory in cross probing, and to display the pin
characteristics in some cases, for instance if a pin is flagged by the ERC tooL.
Add missing check for root sheet when searching sheet hierarchies for
already loaded schematics. This prevents the root sheet from being
omitted when adding new sheets using the root sheet file name.
CHANGED: Make file name tests case sensitive so that schematic sheet
file names on non-Windows systems can be uses as expected.
Warn users when attempting to use schematic file names that only vary
by case sensitivity that doing so will result in a project that is not
portable to Windows.

The new connectivity algorithm had a tendency to cleanup
globally, but that could insert undo records from other sheets
into the current screen's undo stack. Needless to say, this

Check for symbol libraries that somehow ended up in the project file
after remapping occurred and remove all of them to prevent potentially
broken symbol library links.
Add nagware dialog to warn the user and a checkbox to never show the
dialog again.

Remove an existing sheet from the current page that requires a schematic
load from file to prevent a corrupt screen list from causing a segfault.
Merge the edit sheet file loading with the append schematic code since
they are functionally the same. This allows the sheet edit code to
take advantage of all of the added broken symbol library links added in
the recent append schematic fixes.

Also rewrites the PCBNew Find dialog to make use of the above, including:
1) searching in user-defined footprint fields
2) searching in pcb text
3) a history list in the search popup
4) case sensitive searching
5) word sensitive searching
6) the ability to turn wildcard searching on/off
7) better placement of the result when the dialog obscures part of the
window

Previously, for instance after modifying preferences or language,
they were rebuilt but the tools state was not set due to a missing call to SyncToolbars() after rebuilding.
Selecting in Eeschema has major issues, as does highlighting in
pcbnew. So for now we do highlighting in eeschema and selecting
in pcbnew. Improving highlighting for pcbnew would be the next
logical step....

EEschema optimizes wires by merging colinear segments. If a schematic opened without a valid
cache library or missing installed libraries and later saved, this optimization can cause connectivity
errors. In order to fix that we check each pin-wire connection and junctions if necessary.
This adds the functionality to add multiple labels to your schematic at
once by using spaces in the original label name.

It was escaped (replaced by "{slash}") in dialog.
This is right for labels, not for texts.
A consequence was the directives in spice simul can be broken.
Now the graphic text is not escaped.
