There was a way to prevent a database from being re-opened, by creating a column constraint that references a table with a higher id, for example with "check" constraints that contains queries. This is now detected, and creating the table is prohibited. In future versions of H2, most likely creating references to other tables will no longer be supported because of such problems.

changelog_1002_li=-
changelog_1002_li=The JDBC escape syntax {ts 'value'} did not interpret the value as a timestamp. The same for {d 'value'} (for date) and {t 'value'} (for time). Thanks to Lukas Eder for reporting the issue.
changelog_1003_li=File system abstraction\:support replacing existing files using move (currently not for Windows).
changelog_1004_li=MVStore\:the store is now auto-compacted automatically up to some point, to avoid very large file sizes. This area is still work in progress.

changelog_1005_li=The MVStore now automatically shrinks the file in the background if there is no read or write activity. This might be a bit too aggressive; feedback is welcome\!
changelog_1006_li=MVStore\:an IndexOutOfBoundsException could sometimes occur MVMap.openVersion when concurrently accessing the store.
changelog_1006_li=Change default value of PAGE_SIZE from 2048 to 4096 to more closely match most file systems block size (PageStore only; the MVStore already used 4096).
changelog_1007_li=The LIRS cache now re-sizes the internal hash map if needed.
changelog_1007_li=Auto-scale MAX_MEMORY_ROWS and CACHE_SIZE settings by the amount of available RAM. Gives a better out of box experience for people with more powerful machines.

changelog_1016_li=There was a way to prevent a database from being re-opened, by creating a column constraint that references a table with a higher id, for example with "check" constraints that contains queries. This is now detected, and creating the table is prohibited. In future versions of H2, most likely creating references to other tables will no longer be supported because of such problems.

changelog_1021_li=Databases created with version 1.3.175 and earlier that contained foreign keys in combination with multi-column indexes could not be opened in some cases. This was due to a bugfix in version 1.3.176\:Referential integrity constraints sometimes used the wrong index.
