Version numbers are in 3 parts: a major, a medium, and a minor number. The major number is incremented very rarely, when the software is modified in such a way that clients using it need to be recoded or even redesigned. The medium number is incremented when modifications break backward compatibility. For all other modifications, only the minor number is incremented.
The software has been slightly modified to take advantage of the new version of the Time2 Library, t2 2.0.0.
The essential modification is that a new configuration variable
timedomaincatalog
can be set to name a class providing a
non-default time domain catalog. The variable is read by
DatabaseConfiguration
and the catalog is injected into the
Database
constructor by DatabaseFactory
.
The release consists of three JARs:
crnickl-2.0.0.jar
(binaries)crnickl-2.0.0-javadoc.jar
crnickl-2.0.0-sources.jar
There is also a new version of the JDBC Implementation of CrNiCKL:
crnickl-jdbc-2.0.0.jar
(binaries)crnickl-jdbc-2.0.0-javadoc.jar
crnickl-jdbc-2.0.0-sources.jar
There is also a new version of the MongoDB Implementation of CrNiCKL:
crnickl-mongodb-2.0.0.jar
(binaries)crnickl-mongodb-2.0.0-javadoc.jar
crnickl-mongodb-2.0.0-sources.jar
The following changes have been made to the API:
Database
has a new method getTimeDomainCatalog
.
Some constructors of SimpleDatabaseManager
have a new parameter giving
the name of a class providing the time domain catalog.
The constructor of DatabaseConfiguration
has a new parameter giving
the name of a class providing the time domain catalog. The class has also
a new method getTimeDomainCatalog
.
The release also includes a few non-API changes and fixes.
This backward compatible release adds a new Database
method makeSurrogate()
which returns a Surrogate
for a string. It was always possible to create such
strings using a surrogate's toString()
method, but going the other way
required making assumptions and using non-API methods.
Related code modifications have been made in package ch/agent/crnickl/impl
but they do not affect client code directly.

Modifications have been made to JUnit tests in crnickl-test-1.1.0.jar
to
address issues related to Java 7.
Dependencies on crnickl
and crnickl-test
have been upgraded in the
following new releases: crnickl-demo-1.1.5.jar
, crnickl-jdbc-1.1.4.jar
and
crnickl-mongodb-1.0.1.jar
.
This is a refactoring release which behaves like the previous version and is plug-compatible for client applications, except in one trivial case mentionned below. The primary goal of this refactoring is to optimize code reuse between SQL and NoSQL drivers (currently crnickl-jdbc and crnickl-mongodb). The release also includes bug and documentation fixes.
The administrative information included in files is now limited to a copyright notice. Version tags have been removed from all files, because their maintenance cost greatly exceeds their value. Complete file history is available from the SCM (git).
Compared to version 1.1.2, the java code in the following files has been modified:
isErasing()
pulled up isErasing()
pulled up, and consolidate()
deprecatedisErasing()
pulled up isBuiltIn()
deprecatedMany more code modifications have been made in package ch/agent/crnickl/impl but are not listed here since they do not affect client code directly. In addition, various non-code modifications (documentation and administrative information) have been performed on all source files.

There is a new version of the CrNiCKL Demo, crnickl-demo 1.1.4
,
a new version of the CrNiCKL JDBC driver, crnickl-jdbc 1.1.3
,
and a new CrNiCKL MongoDB driver, crnickl-mongodb 1.0.0
.
This is a maintenance release which behaves exactly like the previous version and is plug-compatible for applications. The POM file has been modified to agree with requirements for deployment to the central maven repository.
The release consists of three JARs:
crnickl-1.1.2.jar
(binaries)crnickl-1.1.2-javadoc.jar
crnickl-1.1.2-sources.jar
There is also a new version of the JDBC Implementation of CrNiCKL:
crnickl-jdbc-1.1.2.jar
(binaries)crnickl-jdbc-1.1.2-javadoc.jar
crnickl-jdbc-1.1.2-sources.jar
Likewise, there is a new version of the CrNiCKL Demos:
crnickl-demo-1.1.3.jar
(binaries)crnickl-demo-1.1.3-javadoc.jar
crnickl-demo-1.1.3-sources.jar
This is a maintenance release which behaves exactly like the previous version and is plug-compatible for applications. The organization of source files has been modified to agree with the standard recommended by Apache Maven.
The release consists of two JARs:
crnickl-1.1.1.jar
(binaries)crnickl-1.1.1-sources.jar
(sources only)It was necessary to increment version numbers because the JAR checksums
are different, due to small differences related to builders. Another
change is in the name of the source JAR. The suffix has been modified and
is now -sources.jar
. Previously it was .source.jar
.
There is also a new version of the JDBC Implementation of CrNiCKL:
crnickl-jdbc-1.1.1.jar
(binaries)crnickl-jdbc-1.1.1-sources.jar
(sources only)Likewise, there is a new version of the CrNiCKL Demos:
crnickl-demo-1.1.2.jar
(binaries)crnickl-demo-1.1.2-sources.jar
(sources only)All methods named "delete" have been renamed because delete is a reserved word in JavaScript. Parameterless methods have been renamed "destroy". Methods with a parameter Foo have in most cases been renamed "deleteFoo". Version numbers of classes have been increased: from 1.0.0 to 1.1.0 when defining renamed methods, and from 1.0.0 to 1.0.1 when only referencing them.
The release consists of the following archives:
crnickl-1.1.0.jar
(core system binaries)crnickl-jdbc-1.1.0.jar
(core system + JDBC implementation binaries)crnickl-jdbc-1.1.0.source.jar
(sources only)The versions are available as tags on GitHub.
CrNiCKL (pronounced chronicle
),
a Java database for time series, is released on the web
at http://agent.ch/timeseries/crnickl/.
The release consists of the following archives:
crnickl-1.0.0.jar
(core system binaries)crnickl-jdbc-1.0.0.jar
(core system + JDBC implementation binaries)crnickl-jdbc-1.0.0.source.jar
(sources only)The first archive (core system binaries) is for use by systems with their own implementation of the lower database layer, for example NoSQL implementations. The second is a ready to use JDBC implementation packaged together with the core system. The third contains only sources.
An accompanying demo has been released.
Note. CrNiCKL is a relaunch under a new name of ChronoDB. The software is the same, except that all package names have changed. ChronoDB will remain accessible for a while at http://agent.ch/timeseries/chronodb/ but will not be updated.
