Bugs were fixed. auth.user_id was added as a shortcut for auth.user.id that defaults to None if not logged in. Support was added for all native types on Google App Engine (for example StringListProperty). Python 2.4 support was restored. cache.ram usage statictics were added. Doctest in html.py was fixed. export_to_csv_file now has represent.
Default validators now use the new define_table(....,format='...'). New get_vars and post_vars were added that are compatible in 2.5 and 2.6. A major rewrite of gql.py was done to extend DAL syntax on GAE and to support belongs. *.w2p files are no longer used. welcome.w2p is created automatically, and base apps are always upgraded. The decimal validator allows negative numbers. The 1.74.* version series will be the last with the old DAL. The new DAL is in gluon/dal.py.
This release includes a new cron implementation, Hindi and Spanish translations, progress bars in cached uploads, Ingres database support, and legacy database support for DB2 and MSSQL with non-int primary keys. A default setting was provided for content-type, which may cause strange behavior in old apps when downloading images. IS_UPPER and IS_LOWER now work with Unicode. CLENUP now takes a regexp of allowed/non-allowed characters. rewrite.py now allows dynamic routes. Better error messages were provided for IS_INT_* and IS_FLOAT_* .
Lots of small bugs were fixed. For upload fields, you can choose the Field(...,uploadfolder="..."). The latest wsgiserver is included, which should solve problems with truncated downloads. Default string fields are now 512 bytes. This may trigger a migration on existing tables. The shell has [unlock] buttons. appadmin works on GAE out of the box.
This release fixes a bug in IS_LENGTH and allows actions to return Unicode strings (automatically converted to UTF-8). There are minor typos and bugfixes. form.vars.uploadfield_newfilename is back.
The new logo is in (experimental). The major change is the following replacements: SQLField -> Field, SQLRows -> Rows, SQLXorable -> Expression, SQLQuery -> Query, SQLSet -> Set, and SQLStorage -> DALStorage. The classes with the SQL prefix try for backward compatibility. Now you can use Field everywhere; you never need SQLField or db.Field anymore.
