Lime CRM now requires Python 3.11 on-premise. The new python version must be installed before running the installer. Any pre-existing Python 3.7 should be left where it is.
The installer uses the
py launcher to make sure its starting Python 3.11, even if 3.7 is before it in the
venv created for Lime CRM is now called
lime_crm_venv and is created by Python's built in
venv module, previously it was created by
virtualenv and called
Solutions must be built for python 3.11 before they can be installed.
Elastic Search 7¶
This release comes with Elastic Search 7 only. Previously Elastic Search 5 was used.
The new version enables many optimizations and is used slightly different. More detailed info can be found here.
- Prior to creating a new search index, it is necessary to manually delete the previous data directory (
%LIME_HOME_PATH%\Elasticsearch\data) associated with ElasticSearch 5. Otherwise, old indexes built for ElasticSearch 5 will remain on the server and take up disk space and interfere with the new installation.
- Please verify that there is no globally defined
JAVA_HOMEsystem environment variable in your system configuration. If such a variable exists, kindly remove it to ensure proper functionality (the installer will fail if this variable is set). For instructions on modifying system environment variables on a Windows computer, please refer to the following external resource: Modifying Environment Variables on Windows
Some of the services installed by Lime CRM has changed names in this version. Further the import- and task handler services has been split into two services each.
Lime services (2023.1):
- Lime CRM Event Handler (
- Lime CRM Import Service 1 (
- Lime CRM Scheduler (
- Lime CRM Search Indexer (
- Lime CRM Server Administration (
- Lime CRM Task Scheduler Service (
- Lime CRM Task Service 1 (
- Lime CRM Webfront (
- Lime CRM Webserver (
Lime Component Services (2023.1):
- COM+ Applications → Lundalogik Data Components
We have updated all our Python services to be run as a service with WinSW. This is a change compared to previous versions where some services were installed via a python win32 library from lime-core and some using NSSM.
WinSW is installed in
C:\Program Files (x86)\Lundalogik\LIME Pro Server\Lime Services. There is one
xml for each service. These files are not meant to be edited and will be overwritten by the installer.
The logging for all Python services is now written to file directly from lime-core, previously it used stdout and was written to file by
nssm. This has the benefit that they can all be configured in the same way.
Read more about the logging configuration.
Lime Pro Command Prompt¶
The convenient command prompt on the desktop now has access to both
lime-project at the same time without having to activate any extra venvs.
New SQL Driver for LDC - Microsoft OLE DB Driver for SQL Server
In this version of Lime CRM, we have updated the SQL driver. Previously, the SQL Server Native Client was used. But from now on, LDC uses the Microsoft OLE DB Driver when connecting to the SQL server.
Why are we upgrading the driver?
The SQL Server Native Client has been removed from SQL Server 2022 (16.x) and SQL Server Management Studio 19 (SSMS) and is no longer recommended to use by Microsoft.
The task handler, task scheduler and importer are Celery applications. Celery has not received the necessary patches from its maintainers to enable all its features when running Python 3.11 on Windows yet so in this release we opt to run in
threads connection mode.
New WSGI server¶
Lime CRM Webserver is a python based WSGI Server. We have changed the WSGI server that Lime CRM is run with from Cheroot to Waitress.
- Nginx has been updated to version 22.214.171.124.
- The endpoint /nginx_status/ is no longer externally accessible.
- TLS (https traffic) is terminated in the nginx proxy. In previous versions of Lime CRM, TLS was terminated in the Web Server.
Newer versions of RabbitMQ requires the program
Handle.exe to work properly. This software is automatically installed when you install this version of Lime CRM Server.
What is Handle?
Handle is a utility that displays information about open handles for any process in the system. You can use it to see the programs that have a file open, or to see the object types and names of all the handles of a program. Read more here
The installer now enables
LongPathsEnabled in the registry.
