Server Pro 2.6.1

Release date: 2021-04-23

Image ID: dd382a10a3e5 (Community Edition Image ID: cfd4ec616219)

This release includes performance and stability improvements for handling larger projects. These improvements are backed by changes to data structures in the Mongo database. The changes are implemented in a backwards compatible way for reading existing data, but new data is written in a backwards incompatible format. You may be able to upgrade without making any changes to the database at this time, but in case of a roll-back, you will not be able to read all the newly written data. A future release will migrate the old data to the new format. As with previous updates, please ensure you have a backup before upgrading.

Bugfixes

This release includes important security updates. It fixes some potential XSS vulnerabilities and upgrades to node 12 ahead of node 10 reaching end of life on 30 Apr 2021.
Fallback linearisation breaks PDF/A when not using sandboxed compiles.

New Features

SAML: Add /saml/meta endpoint to fetch Service Provider Metadata.
New configuration parameters for SMTP: SHARELATEX_EMAIL_SMTP_NAME and SHARELATEX_EMAIL_SMTP_LOGGER.
Added configurable AWS Region to email settings (SHARELATEX_EMAIL_AWS_SES_REGION).
Allow Nginx connection limits to be changed.
Administrators can now promote other users to administrator again.
Added ADDITIONAL_TEXT_EXTENSIONS for customisation of editable file types.

Server Pro 2.0.0

Release date: 2019-10-09

Image ID: 8fdd3419f5a5 (Community Edition Image ID: 2cdbdc229d4f)

A lot has changed in the last few years, with ShareLaTeX joining forces with Overleaf to create one incredible authoring platform. Now that the merge is complete it's time to release a new version of ~~ShareLaTeX~~ Overleaf Community Edition and Server Pro!

New Features

This release brings Community Edition and Server Pro up to date with the cloud-based version of Overleaf. A lot has changed since the last release, with too many bug fixes and small improvements to count, but here are a few highlights:

A brand new user interface theme
Improved project dashboard
A new interface for creating (or uploading) files in a project
Linked Files: import a file from another project.
Improved History view

Server Pro

This release of Server Pro includes a few new premium features:

Rich Text mode: write your document like a rich-text document, backed by nice clean LaTeX
Improved Sandboxed Compiles: no more fiddling with group permissions (see below)
Improved Admin Interface: now you can inspect the state of a project from the Admin page, plus many more small improvements

Changes to the Docker-Compose file format

This release adds a few new options to the docker environment. We recommend using our updated example docker-compose.yml file and updating it to reflect your old configuration where necessary.

The new variables are:

ENABLED_LINKED_FILE_TYPES: a comma-separated list-keys, which controls which types of "linked file" are available in the New File modal. Defaults to 'url,project_file', as in the example file.
ENABLE_CONVERSIONS: If set to 'true', will enable on-the-fly file preview conversions using ImageMagick. Set to another value to disable this feature
REDIS_HOST: should be set to the name of the Redis host, same as the SHARELATEX_REDIS_HOST variable. In the case of a simple docker-compose based deployment, this will just be 'redis'. This duplication is, unfortunately, necessary in the short term while users migrate to the new Community Edition and Server Pro images, and will be resolved in a later release.
REDIS_PORT: In case we desire to use the port for Redis other than the default, we need to set the value in REDIS_PORT to be the same as in SHARELATEX_REDIS_HOST, for the same reason described above.

And for Server Pro:

DOCKER_RUNNER: set to 'true' when enabling Sandboxed Compiles with sibling containers. See the updated documentation on Sandboxed Compiles.
SYNCTEX_BIN_HOST_PATH (introduced in 2.0.2): set to <your_sharelatex_data_directory>/bin/synctex. Check Sibling Containers documentation for extra context

Changes to Sandboxed Compiles

We've made some changes to the way the Sanboxed Compiles work. In previous versions, the administrators often needed to fiddle with user and group permissions on the docker socket to get Sibling Containers to work. In this release, we've changed all that so it's handled automatically inside the Server Pro container, so it should just work in the majority of cases.

From this release onwards we will no longer support the old "Docker-In-Docker" method of sandboxed compiles, as it has become more and more difficult to get this to work as time goes on. We strongly encourage admins to consider the newer Sibling Containers method as an alternative.

Upgrading TexLive

You can now opt-in to a new version of TeX Live. The default is still TeX Live 2017, but you can find instructions on how to get TeX Live 2018 or later here: https://github.com/overleaf/overleaf/wiki/Server-Pro:-sandboxed-compiles#changing-the-texlive-image

Before updating to a newer version of TexLive we strongly recommend backing up your data and update to the latest version of Server Pro available.

Database Migrations

The following database migrations have been added, and will run automatically:

Alter the structure of the User model to support future work
Change structure of project.tokens, to enforce uniqueness on the numeric part of a read-and-write sharing token

Administrators and end-users should not notice any change in behaviour due to these migrations.
