Pinba 1.0.0      17 Aug 2012
----------------------------
- Added tag_report2 and tag2_report2 mostly replicating their first versions, 
  but with additional grouping by server name and hostname. (Denis Yeldandi)

- Implemented thread pool. 
  ATM the pool is used only when converting Protobuf packets to Pinba internal structs
  and when deleting outdated data from the request pool. 
  In most cases this means incoming/outdated data is processed MUCH faster 
  and the pools are locked for MUCH less time.

- Fixed reading from timertag table by key.
- Fixed race condition when reading timer tag values.
- Fixed MySQL 5.5 build.

Pinba 0.0.6      26 Nov 2010
----------------------------

- Added missing primary key to timer table.
- Increased default hostname size to 32 chars.
- Changed protobuf proto to use lite runtime (and link against libprotobuf-lite).
- Removed wrong index on tag_id in timertag table.
- Fixed build with MySQL 5.5 (hopefully, as there is no way to know what they'll break next).
- Fixed potential problem with LDFLAGS in configure. (Andrew Sitnikov)
