In order to simplify implementing PBF decoders, I have decided to disable the use of bzip2 and lzma compression. Bzip2 has a poor time/compression ratio tradeoff. I am marking it as obsolete and have removed it from the *.proto definitions. LZMA is untested and unproven. I am classifying it as a proposed extension. I am leaving it in the *.proto definitions so that existing implementations will compile, but there is no need for an implementation to support it. I have updated the Wiki.
Osmosis's decoder has never supported bzip2 or lzma. Osmosis's pbf writer --- the only pbf writer that I am aware of --- has also never supported these formats. The only consequence of this change is that existing decoders that support bzip2 will not compile correctly with the new *.proto definitions until their bzip2 support is removed. For now, the only compression features supported are no compression and zlib, which are both required for a reader implementation. Thanks, and sorry for making a format change, even if it is minor.
