[IPT] IPT 2.5.3 release

[Matthew Blissett]

Dear IPT users,

I have released a new version of the IPT, version 2.5.3.  There are only 
two changes since the previous version:

- The Spanish translation has been completed, for both the user 
interface and the user manual. This is the reason for this release.

- A minor bug when viewing vocabularies in the administration section 
has been fixed. This is probably only of interest for people running 
IPTs in test mode, working on this year's changes to the Darwin Core 
standard.

It's not necessary to upgrade unless you need these changes. 
Instructions are in the manual as usual, and you should check your data 
directory backups are still working before starting the process.

Best regards,

Matthew Blissett
