Issues that are ready to be worked on, in descending order of priority.

• Optimize existing srcset headers #1274 [in progress: morlovich]
• handle pages that set a content-security policy #876 [morlovich has a spec]
• Handle redirects in resource fetching #262 [in progress: otto]
• Insert preload hints #1158 [in progress: morlovich]
• Support Brotli #1148 [in progress: kees]
• automatically disable combining/sharding when running under http2 #1166 [in progress: morlovich]
• IPRO turns application/json into application/javascript #1321
• Don't mangle files that start with the gzip magic bytes #1307
• Allow people to turn on combining etc for resources with ids. Maybe with an id regexp, that could be * or something more restrictive?
• Don't spawn cache cleaning multiple times on large caches #1337
• Respect s-maxage and Age #1287
• .rpms don't have FORTIFY_SOURCE #1301
• Fetching pages with +Debug enables other filters #1190
• inline_google_font_css should use minification #1183
• dedup_inlined_images fails if you switch away from the page mid-load #1002
• Add support for Redis as a caching backend, similar to the existing memcached support. #777 [scheduled: intern project]
• property cache lifetime should be configurable #1311 [in progress: jefftk]
• disallow and allow don't interact right with merging #1294
• Send back a new image size beacon on orientation change #1199
• Allow disabling optimizations via tags on attributes #1320
• Support Apache's environment variables #1179
• Don't override static gzipping #1053
• ngx_pagespeed doesn't allow purging if off at the top level but on in a vhost #1077
• Support non-ascii urls #1023
• Don't accumulate waveforms if no one is looking at them #1127
• Find out when we're breaking things by changing urls. Make the server check for corrupt .pagespeed. urls, look at the referrer, and turn off renaming appropriately.
• Allow UrlValuedAttribute:image on elements with children #1308
• Respect configured forward proxies for fetching #974
• MapProxyDomain doesn't apply to insert_ga #1099
• don't build boringssl if we're linking against system libraries (currently doing wasteful work) #1139
• notice incomplete fetches with serf #1046
• Convert WOFF to WOFF2 for supporting browsers. WOFF2 has a font-specific compression algorithm that makes for much smaller font files.
• Support JPEG-XR #1346
• Support APNG #1347
• Apply extend_cache_images to svgs: #1221
• optimize existing svg files #1231
• Add SRI support. When PageSpeed puts resources on a CDN, put a hash in the html so the CDN can't modify the file. #961
• Add FreeBSD support #1073 and OSX support #612
• Incompatible with mod_ruid2 #635
• create pedantic5 filter to disable optimizations that are not technically allowed even in html5 #1153
• Don't emit type=text/javascript on script tags #1207
• Support other platforms, like ARM #1213

This list is not complete; bugs earlier than #972 haven't been categorized unless they've come up as continuing issues.
