+# 0.10.2 (14th mar 2014)
+- Fixed connection issues to networks with multiple routers sharing the same ssid
+- Option to update to beta releases (Beta testers are welcome)
+- Substituted wifiboxid retrievable through info api
+- Added a "connecting" printer state where it found a printer but couldn't communicate yet. (Not yet implemented for Makerbot's) 
+- When connecting takes to long, we display a warning that the user might have selected the wrong printer type (Not yet implemented for Makerbot's) 
+- API's printer/state doesn't return an error anymore when a printer is just connected
+- Allowing WiFi channels 12 & 13 
+- Fixed issue that control access wasn't properly reset after print
+- Fixed another issue where the box in access point wouldn't give ip addresses
+
 # 0.10.1 (12th feb 2014)
 - miniFactory support
 - Fixed most Makerbot display issues

+
+-- This script creates a new release by copying openwrt image files and release notes to a local
+-- directory and updating the relevant index file with a new entry. This directory is
+-- then synchronized to the release repository online.
+--
+-- USAGE:
+-- The only dependency of this script is the penlight library, which can be installed using
+-- LuaRocks (http://luarocks.org/) as follows: 'sudo luarocks install penlight'.
+-- This script will automatically locate the Doodle3D repo's. 
+-- Index files are fetched from the online repository.
+-- For synchronizing, rsync must have passwordless SSH access to the server, for a
+-- guide, see: http://www.linuxproblem.org/art_9.html.
+-- The scrips expects a alias named 'doodle3d.com', you can add this editing the following file:
+-- .ssh/config
+-- and adding
+-- Host doodle3d.com
+--        User webmaster@doodle3d.com
+--        HostName ftp.greenhost.nl
+-- Some basic sanity checks are built in (unique version, updated release notes, 'clean' openwrt config)
+-- but lots others are still missing (mainly: clean git repo's, freshly built images).
+-- The script must be run from within the openwrt build root. So it's handy to create a symlink 
+-- to this file. You could to something like from the build root: 
+-- ln -s ~/wrt-wifibox-feed/doodle3d-firmware/extra/scripts/publish-wifibox-release.lua .
+-- Then you can start with:
+-- cd trunk ../publish-wifibox-release.lua
+-- Before anything is actually uploaded, you will be asked if that's really what you want to do.
+-- It might be wise to make a backup on the server before updating it, there's a script
+-- to do this on the server: '~/backup-updates-dir.sh'.
+--
+-- To play around with or improve on this script, use and modify the variables 'SERVER_HOST'
+-- and 'SERVER_PATH' below to point to your machine (assuming you have a webserver running there).
+-- Also uncomment and modify UPDATER_BASE_URL. You will have to init the local 'repo' with at
+-- least empty index files ('wifibox-image.index' and 'wifibox-image.beta.index'), or you
+-- could of course mirror the online repository.
+--
+-- TODO (in random order):
+-- * (feature) command-line arguments: overrides, verbosity, allow local mirroring, clear local cache dir, etc.
+-- * (feature) automatically create a backup of the online repo (there's already a script fir this, as mentioned above)
+-- * (feature) check whether git repo's are clean and on correct branch
+-- * (feature) allow local mirroring with a reverse rsync command and rebuilding the indexes
+--   - update manager 'cache' should then be enabled to prevent fetchIndexTable from downloading files
+-- * (feature) automatically (re)build openwrt to ensure it is up to date?
+-- * (feature) update package feed (requires a local mirror for the feed indexing script)
+--   - in this case sanity checks must also be run on package versions/revisions
+-- * (feature) automatically tag (and merge?) git commits?
+-- * (feature) execute as dry-run by default so changes can be reviewed?
+-- * (refactor) rename awkward vars/funcs regarding entries, versions and caches...
+-- * (refactor) replace function arguments 'includeBetas' with a set function like setUseCache to improve readability
+-- * (refactor) replace prints with D() function from update manager or other slightly smarter mechanisms?
