Mozilla Messaging released Thunderbird 52.3.0 on August 16, 2017 to the release channel and all supported operating systems.
The new version of the popular email client is a bug fix release; means, it fixes issues in the client but does not introduce new features to it or make changes to existing ones. Also, no security updates in the release.
Thunderbird's automatic update feature may not pick up the update right now. You can check for new updates with a click on Help > About Thunderbird.
If the new version is not picked up, you may download and install it manually instead. Head over to the official Thunderbird download page and select the version that you are using from the list of supported languages and operating systems.
The new version of Thunderbird fixes the following issues in the email client:
Most of the issues that Thunderbird 52.3.0 fixes impact only a small number of systems the email client is installed on.
Thunderbird 52.3.0 has two known issues that are listed in the release notes. The first affects users who select Send To > Mail recipients on Windows. This does not work anymore. A solution is provided; Mozilla Messaging asks users to install the Microsoft Visual Studio 2015 redistributable runtime library, or the Universal C Runtime for Windows Server to fix the issue.
The second issue causes multiple requests for the master password when Gmail OAuth2 is enabled.
These issues probably don't affect to many users of the email program either. Still, for those affected by at least one of the fixed bugs, it is a welcome update.
Since Thunderbird 52.3.0 does not fix any security issues, there is no rush to install the update unless you are affected by one of the issues that were fixed in the release.
Now You: Thunderbird, or another program? Which software do you use for email?
