+- Update to 9.0.0rc1:
+  * Port asciidoc to run on Python 3.5+ (see https://github.com/asciidoc/asciidoc for the EOL Python 2 implementation)
+  * Drop internal implementation of OrderedDict and use the standard library collections.OrderedDict instead
+  * Implement Dockerfile for running asciidoc
+  * Add Catalan translation
+  * Add docbook5 backend
+  * Fix misspellings in various files and documents
+  * Use UTC for testing instead of Pacific/Auckland (which observes daylight saving time).
+  * Use "with" context statement for opening and closing files instead of older try/finally pattern.
+  * Search sibling paths before system wide paths in asciidocapi
+  * Add manpage for testasciidoc.py
+  * Use argparse instead of optparse for argument parsing
+  * Migrate from A-A-P based build system to Make
