Ladies and Gentlemen ... Its been a long, arduous, up hill battle to get to this point, with all of the changes since v7.0 was released, but we're finally there ... The PostgreSQL Global Development Group is *pleased* to announce the availability of PostgreSQL v7.1 Release Candidate 4, the long awaited successor to v7.0. Before anyone asks what a 'Release Candidate' is, and what happened to 1-3 ... a Release Candidate is what the developers have decided is going to be the Release, based on no known bugs remaining, but want to get more general testing. If, by Friday, April 13th, there have been no bugs reported, all that will happen is that rc4 will get renamed as the official release, no repackaging or anything ... What happened to 1-3? We packaged 1, one of the developers came across a bug before an announcement went out, so we didn't announce ... similar to the other 2. Please NOTE that this is *not* the official release ... this is what we believe, at this time, is going to be the official release, based on extensive testing over the past several months, but if someone reports a bug based on this, it will be addressed and a new package built ... What does v7.1 provide that v7.0 didn't? From our HISTORY file: ================ Major changes in this release: Write-ahead Log (WAL) - To maintain database consistency in case of an operating system crash, previous releases of PostgreSQL have forced all data modifications to disk before each transaction commit. With WAL, only one log file must be flushed to disk, greatly improving performance. If you have been using -F in previous releases to disable disk flushes, you may want to consider discontinuing its use. TOAST - Previous releases had a compiled-in row length limit, typically 8 - 32 kB. This limit made storage of long text fields difficult. With TOAST, long rows of any length can be stored with good performance. Outer Joins - We now support outer joins. The UNION/NOT IN workaround for outer joins is no longer required. We use the SQL92 outer join syntax. Function Manager - The previous C function manager did not handle NULLs properly, nor did it support 64-bit CPU's (Alpha). The new function manager does. You can continue using your old custom functions, but you may want to rewrite them in the future to use the new function manager call interface. Complex Queries - A large number of complex queries that were unsupported in previous releases now work. Many combinations of views, aggregates, UNION, LIMIT, cursors, subqueries, and inherited tables now work properly. Inherited tables are now accessed by default. Subqueries in FROM are now supported. ================= For a more complete list of New Features and Bugs Fixed, please read the HISTORY segment available at: ftp://ftp.postgresql.org/pub/README.v7_1 Source code is available at ftp://ftp.postgresql.org/pub/v7.1 ...
