Over the past week, we have bundled and released new versions of 7.2, 7.3 and 7.4 to address a couple of potentially critical bugs that were recently identified.
For all three versions, these releases address the following:
* Prevent possible loss of committed transactions during crash Due to insufficient interlocking between transaction commit and checkpointing, it was possible for transactions committed just before the most recent checkpoint to be lost, in whole or in
part, following a database crash and restart.
Specific to 7.4, the following has also been fixed:
* Repair possible crash during concurrent btree index insertions This patch fixes a rare case in which concurrent insertions into a btree index could result in a server panic. No permanent damage would result, but it's still worth a re-release. The bug does not exist in pre-7.4 releases.
