+- Update to 0.9.18
+  * Bug Fixes:
+    - fix bug in macOS that caused spurious warnings about missing
+      file in the manifest
+    - hopefully fix macOS bug about launching files using open-with
+      from Desktop
+    - make sure JQuery gets loaded before starting to use Preview
+      javascript functions
+    - fix local links during split that incorrectly used target
+      filename for internal link
+    - create GetEnvironmentVar to make access to environment
+      variables more cross-platform
+    - fix macOS bug when hitting close on the title bar of 
+      MainWindow causing strange window behaviour
+    - hopefully fix macOS segfault on close by disabling Preview
+      timer immediately
+    - fix Windows 7 issues when running batch (.bat) files via
+      OpenExternally (open with)
+    - all error messages are now properly logged
+    - fix improperly disabled open-with menu in Image Tabs popup
+      context menu
+    - removed use of Qt obsolete methods in About and Error Dialogs
+  * New Features
+    - enable use of SIGIL_DEBUG_LOGFILE environment var to control
+      saving debug output to a file
+    - properly update the ncx after merging xhtml files
+    - properly warn users if a multiple rendition epub
+     (multiple OPF files) has been loaded
+    - make Sigil's external XHtml editor work to pass an OPF file
+      (see PageEdit new features)
+    - Allow epub3 metadata editor to edit primary meta tags
+    - Replace buggy cssutils module used in plugins with our own 
+      drop-in replacement fork: css-parser
+    - Updated Mac, Windows, and Linux build documentation
+
+  Be aware that Sigil-0.9.18 no longer enforces the need for epub3
+  to have and support an NCX for the purposes of backward 
+  compatibility with epub2 reading systems. There are, however, 
+  built-in tools to allow users to add backward compatibility 
+  features such as the NCX to their epub3.
