Release Notes

(1st May 2005 - by Andres March)

Improvements:

• The taglib URI was changed to http://www.opensymphony.com/oscache in CACHE-61
• The DiskPersistenceListener escapes '?' now and guarantees that the filenames will be unique based on the cache key, see CACHE-110
• Session objects in cache tags are created only if necessary, see CACHE-88
• The disk persistence configuration key can be accessed now, see CACHE-111

Bug Fixes:

• The CacheFilter doesn't send back a 304 (not modified) response when client cache is de-activated anymore, see CACHE-116
• CacheFilter doesn't support correctly i18N by setting encoding not properly, CACHE-38 and CACHE-159
• Cron expressions - leap days not always matched correctly, CACHE-157
• FindBugs doesn't report that the usage of GetResource may be unsafe if class Config is extended anymore, see CACHE-108
• ConcurrentModificationException on flushGroup, see CACHE-127
• Exception not thrown when not serializable object is persisted instead stack trace is persisted, see CACHE-112
• A few concurrency issues were fixed, see CACHE-170, CACHE-167, CACHE-127

Changes that may affect backwards compatibility:

• The improvement CACHE-88 may change the behaviour of the application, because a session object isn't created anymore even if it wasn't necessary. A web application may react different to a not existing session object.
• The URI change of CACHE-61 from /oscache to http://www.opensymphony.com/oscache affects all JSP's which explicit use the old URI.
