                     AceQL HTTP
                    Release Notes



Introduction
------------

AceQL HTTP is a secure framework of REST like HTTP APIs that allow to 
access to remote SQL databases over HTTP from any device that supports HTTP. 

AceQL HTTP is provided with three client SDKs:
- The AceQL C# Client SDK allows to wrap the HTTP APIs using Microsoft SQL 
  Server like calls in their code, just like they would for a local database.
- The AceQL Client JDBC Driver allows to wrap the HTTP APIs using Java and  
  JDBC calls in their code, just like they would for a local database.
- The AceQL Python Client SDK allows SQL calls to be encoded with standard 
  unmodified DB-API 2.0 syntax.

Security has been taken into account from the design: it is allowed to specify 
and code strong security rules in order to protect the databases. 

AceQL HTTP is licensed through the Business Source License 1.1.
(https://github.com/kawansoft/aceql-http/blob/12.2/LICENSE.TXT)


AceQL HTTP Version 12.3 - 15-Jun-2024
-------------------------------------

What's New: 
- Table names are now case-sensitive when using Metadata calls.
- This allows AceQL to work correctly with SQL Server case-sensitive databases.
  
IMPORTANT NOTE:
If you need to use `sslConnector.SSLCertificateFile` instead of 
`sslConnector.keystoreFile` to enable SSL/TLS,  please refer to this issue, 
which provides a solution:
https://github.com/kawansoft/aceql-http/issues/31.
  

AceQL HTTP Version 12.2 - 21-Feb-2023
-------------------------------------

What's New: 

- BlobUploadConfigurator contains now the getMaxBlobLength() 
  method. This allows fixing a Blob upload size limit in order
  to avoid a DOS attack aimed to saturate the AceQL server.
  
- The new LimitsInfo API allows the future versions of client SDKs to retrieve 
  limits info defined on the server side. How-to usage will be updated in 
  user documentation of C# SDK, JDBC Driver, and Python SDK.

- Tomcat base libraries have been upgraded to 9.0.71 for
  reliability and performance reasons.
  
 
AceQL HTTP Version 12.1 - 06-Dec-2022
-------------------------------------

What's New: 

- Tomcat base libraries have been upgraded to 9.0.70 for
  reliability and performance reasons.

- PostgreSQL base libraries have been upgraded to 42.5.13 for 
  security reasons.

Bugs fixed:

- An Oracle database stored procedure that returns a SELECT would
  in some special cases support only one IN or IN / OUT parameter. 
  This has been fixed.

- Minor Javadoc errors have been fixed.
  
  
AceQL HTTP Version 12.0 - 21-Nov-2022
-------------------------------------

- AceQL HTTP license has been changed from  GNU Lesser General 
  Public License version 2.1 to the Business Source License version 1.1 
  (BSL 1.1). The client SDKs (C#, Java, and Python) will remain using 
  Apache licensing. 

- AceQL HTTP base code is now unique. There is no more code difference
  between different Editions/Plans, but only licensing rights. 
  This simplifies a lot of code maintenance and allows all users to benefit 
  from all features and updates.

- Firewall management includes a new operational mode. This allows automatic
  recording of white lists. See the user documentation.
  
- The StatementNormalizer class has been rewritten with all string and numeric
  values replaced by question marks. This allows both powerful white list 
  checks and easy recording of white lists. See user documentation and 
  StatementNormalizer Javadoc at: https://tinyurl.com/statementNormalizer.

- All logging is now done using SLF4J in order to allow
  one to choose its preferred logging implementation. See
  org.kawanfw.sql.api.server.logging package content.
  Default implementation uses Logback (https://logback.qos.ch).
  
- Default logging may be fully configured using only properties files. 
  This is much easier and does not require any Java code writing & deployment. 
  Of course, it's still possible for advanced users to write and deploy
  their own SLF4J Java implementation. 
  
- Client IP detection has been enhanced by also testing X-FORWARDED-FOR header
  value.
  
- The new HealthCheck API allows the future versions of client SDKs to retrieve 
  server memory info. How-to usage will be updated in user documentation
  of C# SDK, JDBC Driver and Python SDK.

- SqlFirewallManager interface: the method allowExecute has been removed,
  because it was confusing in its naming and the real need for use was 
  not strong enough.
  
- DefaultSqlFirewallManager, the default SqlFirewallManager interface 
  implementation, has been removed. The need for use was not strong enough 
  and would complicate SqlFirewallManager implementations with cumbersome & 
  not real necessary inheritance architecture. 
  (All SqlFirewallManager implementations have been thus retrofitted and 
  do not refer any more DefaultSqlFirewallManager.)
  
- DefaultUpdateListener, the default UpdateListener interface 
  implementation, has been removed. The need for use was not strong enough 
  and would complicate UpdateListener implementations with cumbersome & 
  not real necessary inheritance architecture. 
  
- DefaultSqlFirewallTrigger, a default SqlFirewallTrigger implementation 
  that did nothing and would slow down the software, has been removed.
  
- DefaultUserAuthenticator, a default UserAuthenticator implementation 
  that did nothing and would slow down the software, has been removed.

- DefaultRequestHeadersAuthenticator, a default RequestHeadersAuthenticator 
  implementation that did nothing and would slow down the software, has been 
  removed.
  
- The Maven maven-source-plugin is now used to build the runnable jar and 
  the sources jar.
  
- Tomcat base libraries have been upgraded to 9.0.69.

- Auth0 library has been upgraded to 4.2.1 in order to upgrade automatically
  Jackson base libraries to 2.13.4 for security reasons.

- PostgreSQL library has been upgraded to 42.3.7 for 
  security reasons.


AceQL HTTP Version 11.1b - 22-Jun-2022 (Linux/Unix only)
--------------------------------------------------------

Bugs fixed:
- The new June 22, 2002 Unix/linux installer aceql-http-11.1b.run
  replaces the previous aceql-http-11.1.run because of a jar
  generation bug that would sometimes make
  the software fail when running the Enterprise Edition.


AceQL HTTP Version 11.1 - 15-Jun-2022
-------------------------------------

- Default values of ThreadPoolExecutor creation have been changed in
  the conf/aceql-server.properties file (ThreadPoolExecutor Section).
   - 1) The Queue used is now an always empty 
     java.util.concurrent.SynchronousQueue in order to completely avoid 
     queuing SQL orders, as we don't know how long they will run.
     Filling a Queue, especially a large one,  
     could block waiting users when a long SQL order is processed. 
     Now, per default, a new Thread is systematically created if a 
     SQL request needs one for execution.
   - 2) keepAliveTime is now 60 seconds. 
   - 3) For Community Edition: A message warning displays at startup if
        the ThreadPoolExecutor properties values in the used
        aceql-server.proprties file are not the same as the new values.
   - 4) For Enterprise Edition: A message warning displays at startup if
        the "workQueueClassName" property value is not 
        "java.util.concurrent.SynchronousQueue" and if the 
        "capacity" property value is > 100.  

- Core Threads (corePoolSize value) are now all pre-started per default. 
  This ensures that client users feel the lowest latency possible 
  when their client app calls SQL statements.
  This default behavior may be ignored, see User Documentation.
  
- Enterprise Edition: at server startup, the remaining days and expiration 
  date of the current license is displayed/
   
- Maven is now used - instead of Ant - to build the deployed runnable   
  jar and sources jar.


AceQL HTTP Version 11 - 10-Jun-2022
-----------------------------------

What's New: 
- Software has been divided into a Community (free & open source) and
  an Enterprise version. See www.aceql.com/pricing and user documentation 
  for more info.
- StatementNormalizer creation. See Javadoc.
- TCL calls are not any more firewalled because 
  of unnecessary implementation complexity and because it's globally useless.
- The DenyTclManager SqlFirewallManager has thus been suppressed because
  TCL calls are not any more firewalled.
- Add DenyOnBlacklistManager & AllowOnlyOnWhitelistManager.
- DenyExecuteUpdateManager has been renamed to less ambiguous name
  DenyDatabaseWriteManager.
- runIfStatementRefused() has been moved from SqlFirewallManager interface 
  to new SqlFirewallTrigger interface.
- New SqlFirewallTrigger.runIfStatementRefused() implementations: 
  BanUserSqlFirewallTrigger, BeeperSqlFirewallTrigger, 
  JdbcLoggerSqlFirewallTrigger, JsonLoggerSqlFirewallTrigger.
- Add UpdateListener calls to batch methods.
- DefaultPropertiesPasswordManager: the properties_password_manager.properties
  file must now be located in the same directory of the aceql-server.properties
  file.
- Tomcat base libraries have been upgraded to 9.0.64.
- PostgreSQL base libraries have been upgraded to 42.3.3 for 
  security reasons.
- Gson base libraries have been upgraded to 2.8.9 for 
  security reasons.

- Postgresql base libraries have been upgraded to 42.3.2. 

Bugs fixed:
- SqlEvent.toString() and ClientEvent.toString() would not display 
  correctly parameter values. This has been fixed.
  
  
AceQL HTTP Version 10.1 - 04-Jan-2022
-------------------------------------

What's New: 
- The new JdbcUserAuthenticator allows the client-side to authenticate
  using a JDBC query against a SQL table. See JdbcUserAuthenticator
  Javadoc and User Guide.
- The new ServerQueryExecutor allows future versions of C#, Python, 
  and Java JDBC Driver client versions to call a server Java program 
  that returns a ResultSet. See ServerQueryExecutor Javadoc for more info.
  This will be fully documented later in the future client versions 
  to be released in January 2022.
  

AceQL HTTP Version 10.0 - 21-Dec-2021
-------------------------------------

What's New: 
- The CsvRulesManager now reload all rules if the CSV is updated.
- The new CsvRulesManagerNoReload SqlFirewallManager implementation
  works the same as CsvRulesManager, but prohibits the reloading of
  the rules if the CSV file is updated. 
- SqlActionEvent has been renamed to SqlEvent and moved to
  org.kawanfw.sql.api.server package. 
- SqlEvent has a new parameter getter: isMetadataQuery().
- SqlEvent.getParameterStringValues() allows to get the list
  of parameters object values casted to string. 
- The SqlFirewallManager APIs have been refactored to limit the 
  number of parameters to some methods. The new SqlEvent class is used 
  for this. 
- Tomcat base libraries have been upgraded to 9.0.56.

Bugs fixed:
- org.kawanfw.sql.api.server.StatementAnalyzerUtil was public instead
  of hidden. This has been fixed.
  

AceQL HTTP Version 9.0 - 02-Dec-2021
------------------------------------

What's New: 
- The new UpdateListener interface allows to define listeners and thus actions 
  to trigger when a database is updated.
- The new /get_database_info API allows client side programs to easily
  get all info about the remote database and the remote JDBC Driver.

Bugs fixed:
- A default Java icon instead of the AceQL icon was displayed in one of the 
  message window. This has been fixed.
- StatementAnalyzer was missing the isInsert() method. This has been fixed.


AceQL HTTP Version 8.2 - 06-Nov-2021
------------------------------------

What's New:  
- The new Logger format provided by DefaultDatabaseConfigurator.getLogger() 
  includes now trailing date/time.
- DefaultDatabaseConfigurator: Multi-line log messages are now per default 
  flattened into one line log entry/message. This may be changed by overriding
  DefaultDatabaseConfigurator flattenLogMessages boolean value. See code.
- PropertiesEncryptor class call is now done using a Windows bat or Linux Bash.
  See Server Installation and Configuration Guide. 
                
Bugs fixed:
- sqlFirewallManagerClassNames split on comma separated class names could fail.
  This has been fixed.

 
AceQL HTTP Version 8.1 - 19-Oct-2021
------------------------------------

What's New:         
- Tomcat base libraries have been upgraded to 9.0.54.
             
Bugs fixed:
- StatementAnalyzer.isWithSemicolons() would always return false.
  This has been fixed.
- Spaces were not supported around commas in sqlFirewallManagerClassNames
  array in the aceql-server.properties files. This has been fixed.   
- sqlFirewallManager.runIfStatementRefused() would not set the values of 
  parameter List<Object> parameterValues on some SQL calls. This has been fixed.   
- A SELECT containing a column named FULLTEXT induced request rejection by 
  any SqlFirewallManager implementation.  The bug is due to an external
  Java library code. This has been temporarily fixed by replacing FULLTEXT 
  occurrences by _FULLTEXT_ when checking the SELECT. 


AceQL HTTP Version 8.0 - 01-Sep-2021
------------------------------------

What's New:
- AceQL Server may be run in stateless mode. See conf/aceql-server.properties 
  comments the AceQL Manager Servlet Section & User Documentation.
- Core has be changed to support INSERT and UPDATE calls in batch
  mode  from C# Client SDK, Java Client JDBC Driver, and Python Client SDK.
- The garbage collectors thread for the abandoned/unclosed JDBC Connections 
  has been suppressed in order to simplify the architecture. Cleanup is now
  done using a Tomcat JdbcInterceptor class implementation. This eliminates 
  the need for a dedicated background thread.
- Tomcat base libraries have been upgraded to 9.0.52.
- Waffle library has been upgraded to 3.0.0.


AceQL HTTP Version 7.2 - 15-Jun-2021
------------------------------------

  for encrypting property values in the aceql-server.properties file.
- Tomcat embedded version has been updated from 8.5 to 9.0 (9.0.45).   
- The Windows user interface design uses now a more modern Look and Feel.
- The Windows user interface supports now the dark mode.

Bugs fixed: 

- Ugly embedded Tomcat messages/logging on startup have been disabled.

  Linux version.
- Tomcat base libraries have been upgraded to 8.5.63.


AceQL HTTP Version 6.3 - 05-Dec-2020
------------------------------------

What's New:

- In addition to UserAuthenticator, the new RequestHeadersAuthenticator interface 
  provides an alternate or supplementary authentication mechanism.
  RequestHeadersAuthenticator implementation allows to check the HTTP request 
  headers sent by the client side, and thus to grant or forbid access to the AceQL Server.
- Tomcat base libraries have been upgraded to 8.5.60.


AceQL HTTP Version 6.2 - 17-Nov-2020
------------------------------------

What's New:

- The new session.timelifeMinutes property in aceql-server.properties  file
  allows defining the session lifetime of client users without any programming.
- In SessionConfigurator interface and dependencies: the getSessionTimelife() method
  has been renamed to getSessionTimelifeMinutes() for the sake of clarity.
  
Bugs fixed:

-  JwtSessionConfigurator.verifySessionId(String sessionId) and 
   DefaultSessionConfigurator.verifySessionId(String sessionId) would not 
   verify correctly session expirations. This has been fixed.


AceQL HTTP Version 6.1 - 24-Oct-2020
------------------------------------

What's New:

- Default Java memory configurations are now -Xms256m -Xmx4096m on both
  Windows and Linux in order to support a heavy load. 
- Most base libraries have been upgraded to the latest version.
  

AceQL HTTP Version 6.0 - 19-Sep-2020
------------------------------------

What's New:

- Java vendor and version are displayed at server startup.
- JDBC Statement.execute() calls are now supported.
- Statement.setMaxRows(int) is now supported when called
  by a Java client.
- The aceql-server.properties model file contains now documentation
  on testOnBorrow & validationQuery attributes and how to  ensure that 
  the JDBC Connection Pool will still accessible after the restart 
  of the SQL engine in use.
- Implement server side JDBC metadata calls. This will
  allow the Client Java SDK to be plugged as a real JDBC Driver.
  (The AceQL JDBC Driver is work in progress).
 - Add /get_catalog and /get_schema API.
 - Included PostgreSQL Driver has been updated to 42.2.5.
 - Tomcat base libraries have been upgraded to 8.5.58.
 
Bugs fixed:
- An SQLException could be swallowed during a transaction (autocommit off). This
  could lead to subsequent errors when trying to re-use the Connection in some
  db engines such as PostgreSQL.
  (org.postgresql.util.PSQLException: ERROR: current transaction is aborted, 
  commands ignored until end of transaction block).
  This has been fixed: Connections in autocommit off are now always rollbacked 
  in case of SQLException.
- Columns were in lowercase when sent to the client. This has been fixed.
- Empty string SQL parameters ("") were refused by the AceQL Server. 
  This has been fixed.
  
  
AceQL HTTP Version 5.1 - 03-Aug-2020
------------------------------------

What's New:

- The new API WebServerAPI.isServerRunning() has been added.
- An error message is displayed if an attempt of calling more than one
  AceQL instance in the JVM is detected.
- NullPointerException throws are replaced by Objects.requireNonNull().
  This makes easier for API users to debug NullPointerExceptions.
- Tomcat base libraries have been updated to 8.5.57 because of security 
  requirements.
  
Bugs fixed:
- Remote client Windows authentication calls could stop the server. This has 
  been fixed.
- The database schema download could fail for SQL Server. This has
  been fixed.


AceQL HTTP Version 5.0.4 - 04-Jul-2020
--------------------------------------

What's New:

- Some base libraries have been updated.
- The conf/aceql-server.properties includes now an example of the usage of
  the Tomcat JDBC Pool removeAbandoned & removeAbandonedTimeout properties.

Bugs fixed:

- nvarchar, nchar, ntext would not support NULL values. This has been fixed.


AceQL HTTP Version 5.0.3 - 15-Jun-2020
--------------------------------------

What's New:

- Windows interface signals when the user tries to reopen the app instead  
  of redisplaying it from the taskbar. 
  
- Tomcat base libraries have been updated to 8.5.56 because of security 
  requirements.

Bugs fixed:

- Float values could be rounded. This could be a problem for Python client SDK.
  This has been fixed.



WINDOWS VERSION ONLY - AceQL HTTP  Version 5.0.2b - 25-Apr-2020
---------------------------------------------------------------

What's New:

- Support for Java 13 and 14. 
  It is highly recommended to upgrade to this AceQL version on all 
  Windows installations using Java > 8.


AceQL HTTP Version 5.0.2 - 22-Apr-2020
--------------------------------------

What's New:

- Javadoc has been enhanced for the UserAuthenticator interface and for 
  the provided implementation classes.
- Special chars (in escaped format) are now supported in LDAP Distinguished Names.

Bugs fixed:

- The schema produced by the db_schema_download API would not include correctly 
  the database tables with MS SQL Server. This has been fixed.
 

AceQL HTTP Version 5.0.1 - 10-Apr-2020
--------------------------------------

Bugs fixed:

- SELECT calls with more than 20Kb output could randomly fail because 
  of a bug in Glassfish javax.json JSON parser that inserts a \r\n at 
  each 20Kb output.
  This has been fixed by calling JsonGenerator.flush() on each
  SQL row dump.


AceQL HTTP Version 5.0 - 08-Apr-2020
------------------------------------

What's New:

- The software has been rewritten to allow quick start & standard usage 
  without any coding and without code injection: standard but complete 
  configuration may be done entirely by defining values in the 
  aceql-server.properties file. 
  Sophisticated firewalling can be done through a CSV File without any coding.
  Advanced usage is still possible through code injection using Java classes. 
  
- The new authentication architecture allows to plug-and-play existing built-in
  authentication classes without any coding or code injection, just by defining
  values in the aceql-server.properties file.
  This version provides default authentication against a LDAP server, against a 
  SSH Server, against a Windows Server and against a Web Service. 
  Your own legacy authentication usage is nonetheless supported through code 
  injection with Java classes.
  
- The aceql-server.properties file has been reorganized and simplified.

- JSON parser javax.json has been updated to 1.1.4. Tomcat base libraries
  have been updated to 8.3.53 because of Security requirements.
   

AceQL HTTP Version 4.1 - 13-Feb-2020
------------------------------------

What's New:

- The new CsvRulesManager SqlFirewallManager implementation allows to
  fine control access to SQL tables without any Java programming.
  Rules are declared in a CSV file that is loaded at server startup. 
  Rules are checked for each incoming SQL call. 
  See the User Guides & Javadoc for more info.


AceQL HTTP Version 4.0 - 15-Jan-2020
------------------------------------

What's New:

- SQL firewalling is now done through the SqlFirewallManager 
  interface. SqlFirewallManager concrete classes may be chained 
  to easily add new rulesets. This also allows to 
  properly isolate and reuse firewalling code.
  Default built-in implementations are provided for an easy 
  startup without any coding. 

- The new metadata API allows downloading a remote database schema
  in HTML or text format, to get a remote database main properties, 
  to get the list of tables, and to get the details of each table.
  It also allows wrapping remote tables, columns, indexes, etc. into
  easy to use provided Java, C# and Python classes in the client SDKs: 
  Table, Index, Column, etc.
  HTML and text schemas are rendered with SchemaCrawler (www.schemacrawler.com).
  The metadata API allows exposing more easily the databases along with the 
  schemas, without any need to communicate, maintain or synchronize separated
  documentation for the API users. Users are thus autonomous to explore 
  the metadata and schema of the exposed databases.  
  
- StatementAnalyzer has been retrofitted with an external heavily used 
  and highly supported SQL parser  (JSqlParser library - 
  https://github.com/JSQLParser/JSqlParser).
  
- Tomcat base libraries have been updated to 8.5.50 (Security requirements). 

- AceQL HTTP requires now Java 8 or higher.
   

AceQL HTTP Version 3.2.2 - 16-Sep-2019
--------------------------------------

Bugs fixed:
- DECIMAL SQL type passed from client side was ignored. Thus has been fixed.
- DATE, TIME, TIMESTAMP could be malformed when called from a stored
  procedure this has been fixed.
 What's new:
- Update Tomcat base libraries to 8.5.45 (Security requirements). 



AceQL HTTP Version 3.2.1 - 10-aug-2019
---------------------------------------

Bugs fixed:
- aceql-server -stop was returning -1 exit code instead of 0. It
  could cause a problem when using CI tools like Jenkins. This has been fixed.
 

AceQL HTTP Version 3.2 - 23-apr-2019
------------------------------------

What's new:
- Update Tomcat base libraries to 8.5.40 (Security requirements).

  
AceQL HTTP Version 3.1 - 24-dec-2018
------------------------------------

What's new:
- destroy() call has been added to main servlet ServerSqlManager for
  clean shutdown of ThreadPoolExecutor without warnings. 

Bugs fixed:
- HttpServletRequestHolder could in rare cases collide request parameters 
  from concurrent clients. This has been fixed. 


AceQL HTTP Version 3.0 - 17-dec-2018
------------------------------------

- AceQL open source / Community Edition now supports all main database
  vendors.
- Main servlet is now async for better reliability and performances.
- DatabaseConfigurator.allowStatementAfterAnalysis method 
  has been renamed to allowSqlRunAfterAnalysis for the sake of
  clarity.
- Uses newest Tomcat 8.5.35 embedded libraries for security reasons.
- Update other misc Maven dependencies.


AceQL HTTP Version 2.1 - 18-jun-2018
------------------------------------

What's new:

- This version now supports stored procedure calls from client side. 
  See you preferred AceQL client SDK for usage.
- Server could crash in case or RuntimeException. These runtime exceptions
  are now caught.
- Windows version is now fully 64 bit.


AceQL HTTP Version 2.0 - 28-feb-2018
------------------------------------

What's new:

- Server allows to create new Connection without re-authentication.
- It is now possible to create and use from client side more than
  one Connection on the same database.
  
- Stateful mode is now the main and only mode. This simplifies
  the software architecture, the user documentation and ease of 
  used for developers.
  
- DatabaseConfigurator.getConnectionMaxAge() has been removed 
  because of duplicate usage. (Same kind of value can be set when 
  defining Connection pool whatever pool system is used).
  
- DefaultSessionConfigurator: getSessionTimelife() is now 0 
  (infinite session lifetime) instead of 12 hours.
  
- Connections Store cleaning has been completely rewritten. A 
  cleaning thread is regularly launched instead of a permanent
  thread.
  
- Use last Tomcat 8.5 librairies (v. 8.5.28).



WINDOWS VERSION ONLY - AceQL HTTP Version 1.0 - 27-dec-2017
-----------------------------------------------------------

What's new:
- Java 9 is now fully supported on Windows.


AceQL HTTP Version 1.0 - 20-dec-2017
------------------------------------

What's new:
- Java 9 is now fully supported on Linux.
- DefaultDatabaseConfigurator.getConnectionMaxAge() returns now 0
  for consistency with other APIs.
- Dependencies have been updated.
- As Beta period is expired, AceQL HTTP Professional requires now
  a 30-day license key.

Bugs fixed:
- Setting DatabaseConfigurator.getConnectionMaxAge() to 0 was
  not taken into account by internal code. This has been fixed.
  

PRO EDITION ONLY - AceQL HTTP Version 1.0-beta-5.2 - 31-oct-2017
----------------------------------------------------------------

What's new:
- Beta period has been extended to November 10, 2017.


WINDOWS VERSION ONLY - AceQL HTTP Version 1.0-beta-5.1 - 20-sep-2017
--------------------------------------------------------------------

What's new:

- An item menu has been added in Help Menu to display Release Notes.
- Standard Mode: useless & annoying Tomcat red warnings messages 
  are not anymore displayed at server startup.
- Jar icons are displayed.


AceQL HTTP Version 1.0-beta-5 - 13-sep-2017
-------------------------------------------

What's New:

- The signature of DatabaseConfigurator.login method has been changed 
  and has 2 more parameters: database and ipAddress.
  This allows implementation code to know to which database the 
  client wants to connect and to get IP address of client if
  necessary for security reasons.
  
- Thus, the previous 1.0-beta-4 DatabaseConfigurator implementations 
  are  not compatible with this 1.0-beta-5 version: the login method 
  signature must be changed.

- The org.kawanfw.sql.api.server.util.HttpServletRequestStore and 
  org.kawanfw.sql.api.server.util.ServerInfo have been suppressed.
  The methods were useless.
  
- The Tomcat dependencies have been updated to in order to use last 
  8.5.20 version.
