I (and others) think it would be an excellent idea for a 1.15 release to be created, with new maps, a backported client to get new menus etc, and auto download turned on.
Why? because few people play new maps, and that rather sucks, same old maps again and again is boring. its crap for the players because its boring and its crap for the mappers because with a few exceptions, getting your custom map on a server means 90% of the people leave because they cant download it or dont want to wait for hours at 5kb/s. A 1.15 release with a whole bunch of new maps would provide some refreshing new content, and because a http autodownload is turned on by default, new maps can download easily in future too.
In order for this to happen, there needs to be a release date that is stuck to, and preferably fairly soon too, tentatively thinking sept. 24.
if you have a map in progress, can you finish it within a month or so? Or if your map is finished possibly polish it up for a release?
Not thinking of including every map that has been produced, only good ones, eg of around the quality of the stock maps.
PS. currently this is unofficial, no word from the devs. (EDIT: will be ok to put on official downloads page, given high quality)
comments/suggestions/i will finish my map!'s ?
EDIT:
Release Date: Sept. 24
List of maps (not finalised) in no particular order, please make suggestions: -Thermal:? currently final. good map imo, a little rough around the edges tho.
-Ancient Remains: to include, i think DASPRiD said he had a new version with brighter indoors, get that if possible. edit: he said he would make a new release, for 1.2 i guess. since thats a long way off, this release will include Ancient Remain 1.0.
-Sokolov:? looks nice but rather laggy and unconventional so it hasnt been tested much, to my knowledge

-ATCS3: to include, solid map - well tested.
-Cerberus: to include pending a final version? seems well tested.
-Cleanser: final, include probably only tested on dretchstorm but seemed well received.
-Flap: im unsure, i think i only ever played one game on it. Anyone else?
-Gamma Core b6: will need a final version, it also has the problem with the vent atm, but it has been played alot, at least on funzone.
-Gloomb2: nice map, but chances of a final version are slim, it would seem.
-Meep b2: also good map, well tested, but chances of a final seem equally unlikely.
-Metro b 1.2: really nice map, plays v. well. will have to see if kosad can make a final.
-Procyon: big, but solid and well tested map. to include i think.
-Hamunaptra: its nothing awesome but its not as bad as some people say it is, its fairly well tested too. include?
-Pulse: v. nice, but issues with human spawn point at start, a beta to change this doesnt look likely.
-Research Station Omega: i am unsure. anyone else?
-Sectorb17: final, its an ok map i think, but im kinda biased

-Sedna b3: im not sure, would need a final anyway.
-Sirius b2: to include pending final, i think, anyone?
-Stamina b2: well tested, its got a horrible camp spot that would need to be fixed in a final.
-UTCS b2: to include pending final, well tested.
-GroundSource b1: I like the looks of it, but have barely played it, also would need a final. anyone?
Nano b1: nice small map - to include pending final version.
Eden: final in time?
Derelict b4: imo good map, chances of a final are low tho.
Any maps not on the list arent there because either i didnt think they are good enough quality/suitable for whatever reason, or i just forgot them, feel free to make suggestions.
