We are pleased to announce Lepton EDA release 1.9.11.  This
release represents 534 commits by 4 people, bringing several
improvements and bug fixes to the code.

About
=====
Lepton EDA is a suite of free software tools for designing
electronics. It provides schematic capture, netlisting into
over 30 netlist formats, and many other features. It was forked
from the gEDA/gaf suite (http://wiki.geda-project.org/geda:gaf)
in late 2016 by most of its active developers at that time.

The project team maintains traditional and evolutional (but no
longer conservative) development of tools in the suite.  There are
no issues with support of new Guile versions or known Guile vs
Python problems.

Release notes
=============

We encourage you to test this release and provide
feedback either to our issue tracker at

  https://github.com/lepton-eda/lepton-eda/issues

or to the mailing list geda-user AT delorie DOT com.

You can also chat with us at https://gitter.im/Lepton-EDA/.

  packaging Lepton for several *nix distributions.

Changes since version 1.9.10 (excerpt from the NEWS file)
=========================================================
### General changes:
- Executable scripts `lepton-netlist` and `lepton-symcheck` have
  been moved to the *utils/* directory.  Their Scheme modules have
  been moved to the directory with Scheme files of `liblepton`.

- Separate *gettext* domains of `lepton-netlist` and
  `lepton-symcheck` have been removed.

- As a side effect of this transition, the messages by symbol
  checker are now translated in `lepton-schematic` GUI.

- More Scheme strings have been added to translation.

- Two Scheme test suites, `liblepton`'s and `lepton-netlist`'s
  ones, have been merged into one.

- Unit test for promotable attributes has been added.

- Old changelog files (*ChangeLog-1.0*) have been moved into one
  directory and renamed.

### Changes when building from source:
- Build order has been changed and now `libleptonrenderer` is
  built before `liblepton`.

### Changes in `lepton-cli`:
- The tool used to silently skip missing symbols on export without
  rendering any placeholders. Rendering of placeholders has been
  fixed.

- In some cases, for instance, when a Scheme script was evaluated
  by the tool and no renderer was available, it output assertion
  failures for text objects during calculation of their bounds,
  which has been fixed.

### Changes in `lepton-netlist`:

- Localization support has been added.  The utility had no
  localization support since rewriting it in Scheme.

- The famous Scheme backend `spice-noqsi` has been added to the
  list of backends. The directory with examples contains now its
  documentation and example schematics.

### Changes in `lepton-symcheck`:

- Localization support has been added.  The utility had no
  localization support since rewriting it in Scheme.

### Changes in `lepton-schematic`:
- Log messages about `symversion` mismatch are no longer emitted
for missing schematic symbols.

- `symversion` attribute changes are now detected when a page is
opened. Previous behavior was to check just the first page passed
on the `lepton-schematic` command line.

- Log messages related to `symversion` have been changed to be
more compact and comprehensible.

- Several dialogs and dock widgets now have shorter and more
  uniform titles.

- The "Major symbol version changes" dialog has been improved by
making it more informative and non-modal. A new dialog instance
is opened for each page with symbol version changes.

- The dialogs "Add picture", "Select picture" and "Execute script"
  now have file filters, which eases selection of supported files.

- A new boolean configuration parameter has been added to the
`schematic.gui` group: `use-toplevel-windows` ( `false` by default).
Setting it to `true` allows the following widgets to behave like
top-level windows (i.e. do not stay on top of the main window):
  - Page manager
  - Log window
  - Edit text
  - Color scheme editor
  - Object properties
  - Options
  - Font selector
  - Find text results

- `lepton-schematic` now uses new (more compact) placeholders
for missing schematic symbols. Traditional placeholders (giant
red triangles with an exclamation mark and two lines of text)
can be turned back on by setting the `small-placeholders` key
in the `schematic.gui` group to `false`.

- The same font, defined in the `font` configuration key of the
  `schematic.gui` group, is now used for printing and rendering of
  objects in GUI.

- Several rendering issues, manifesting themselves on some modern
  distributions where new Pango library (1.44) is used, have been
  fixed:
  - Different scaling of overbars on zooming.
  - Wrong alignment and position of lower aligned text in printed
    output.
  - Changing of vertical spacing between paragraphs of text
    separated with empty lines on zooming.

- Historically, text lines of the same object size with different
  size of glyphs, for instance, all uppercase and all lowercase,
  might be rendered as if they have different baseline position.
  For example, `-` (*minus*) and `_` (*underscore*) could be
  rendered on the same height, depending on alignment.  This has
  been changed, and now logical extents of text are used to
  calculate and properly set its position.

- Showing/hiding of hidden text can now be set individually on per
  page view basis.

### Changes in `lepton-upcfg`:
- Fixed a logging issue when the utility is called with some file
  path as a command line parameter.

- The utility now has its own manual page `lepton-upcfg(1)`.

### Changes in `lepton-attrib`:
- The source code of the program has been transformed into a
  library, `libleptonattrib`, and an executable script written in
  Scheme.  Thus, C functions of the new library can now be used in
  other tools.

- The option `--quiet` has been removed.

### Changes in `liblepton`:

- The procedure `process-gafrc()` from the module `(netlist)` has
  been moved to the module `(lepton rc)` to be available for other
  utilities.

- A new Scheme function, `anyfile-config-context()`, and its C
  counterpart, have been added to the library.  In future, they
  can be used to support additional configuration files, for
  example, files containing color schemes or component library
  descriptions.
