Here are links to the new puzzles announced on the forum this year by monthly summary. I will try to find some time to incorporate previous lists as well.

P.S. At some point, with work, this can expand to summaries of new puzzles each month for all years. If you would like to make a summary of a month past feel free to start a topic for it in this forum. Rentlix and others have provided a good model for this. After it has received feedback I can include it in this thread.
P.P.S. Thanks to Rentlix for the 2010 summaries, Steryne for the links to them and Doubleyou for the idea to create and sticky this.
P.P.P.S. Thanks to Steveo and Ender Delphiki for the 2011/2012 summaries.
