Enhancements
- Shell tool: the built-in commands EXIT, HELP, ?, LIST, and so on didnt work with a semicolon at the end.
- JDK 1.5 is now required to build the jar file. However it is still possible to create a jar file for Java 1.4. For details, see buildRelease.sh and buildRelease.bat. As an alternative, compile using JDK 1.5 or 1.6 and use Retrotranslator to create a Java 1.4 version http://retrotranslator.sourceforge.net/).
- When deleting or updating many rows in a table, the space in the index file was not re-used in the default mode (persistent database, b-tree index, LOG=1). This caused the index file to grow over time. Workarounds were to delete and re-created the index file, alter the table (add a remove a column), or append ;LOG=2 to the database URL. To disable the change, set the system property h2.reuseSpaceBtreeIndex to false.
- Identifiers with a digit and then a dollar sign didnt work. Example: A1$B.
- MS SQL Server compatibility: support for linked tables with NVARCHAR, NCHAR, NCLOB, and LONGNVARCHAR.
- Android: Workaround for a problem when using read-only databases in zip files (skip seems to be implemented incorrectly on the Android system).
- Calling execute() or prepareStatement() with null as the SQL statement now throws an exception.
- Benchmark: the number of executed statements was incorrect. The H2 database was loaded at the beginning of the test to collect results, now it is loaded at the very end. Thanks to Fred Toussi from HSQLDB for reporting those problems. However the changed do not affect the relative performance.
- H2 Console: command line settings are no longer stored in the properties file. They are now only used for the current process, except if they are explicitly saved.
- Cache: support for a second level soft-references cache. To enable it, append ;CACHE_TYPE=SOFT_LRU (or SOFT_TQ) to the database URL, or set the system property h2.cacheTypeDefault to "SOFT_LRU" / "SOFT_TQ". Enabling the second level cache reduces performance for small databases, but speeds up large databases. It makes sense to use it if the available memory size is unknown. Thanks a lot to Jan Kotek!

iRad Database 1.0.2 is a highly-efficient, high-quality DICOM image server that functions as an optional database for iRad. iRad Database allows JPEG lossless and non compressed transfer syntaxes. iRad Database is a precompiled version of dcm4jboss and jboss.

Find Database Tables 1.0 is the right solution if you have a bunch of MySQL tables in your database that you aren't sure if you use anymore while finding them can be tough and daunting and you're afraid to delete any because that one obscure script you wrote years ago may still use it. Simply log onto your database sever, select your database, select the folder that has your scripts, and let Find Database Tables do the searching for you!

Major Features:

1. Fast Searching
2. View the table data - make sure if you really want to delete the table or not
3. View the scripts where a table was found
4. Drop unwanted tables right from the application
5. Export the results to a CSV file that can be used in any spreadsheet application
6. Can view table data, scripts, and delete tables while the searching is going on

ACR Codes Database 1.2 brings a powerful application which has the aim to browse, search and generate ACR Codes (acr.org). It is used to generate ACR codes for our teaching files database. It is available for MacOS 9.x and Windows OS. It includes all 6500 ACR Codes

Requirements: All Mac
