+# Changelog
+
+All notable changes to this project will be documented in this file. 
+
+Note - All hash comments refer to the issue number. Eg. #169 refers to https://github.com/markn86/moodle-mod_customcert/issues/169.
+
+## [3.1.21] - 2018-05-17
+### Fixed
+- Race condition on certificate issues in scheduled task (#173).
+- Ensure we backup the 'verifyany' setting (#169).
+- Fixed encoding content links used by restore (#166).
+
+## [3.1.20] - 2018-01-23
+### Fixed
+
+- The fatal error ```Can't use method return value in write context``` would occur in PHP < 5.5 . Note - this fix does not need
+  to be applied to newer branches as the Moodle versions require PHP > 5.5.
+
+## [3.1.17] - 2017-11-13
+### Added
+- Added capability ```mod/customcert:verifyallcertificates``` that provides a user with the ability to verify any certificate
+  on the site by simply visiting the ```mod/customcert/verify_certificate.php``` page, rather than having to go to the
+  verification link for each certificate.
+- Added site setting ```customcert/verifyallcertificates``` which when enabled allows any person (including users not logged in)
+  to be able to verify any certificate on the site, rather than having to go to the verification link for each certificate.
+  However, this only applies to certificates where ```Allow anyone to verify a certificate``` has been set to ```Yes``` in the
+  certificate settings.
+- You can now display the grade and date of all grade items, not just the course and course activities.
+- Text has been added above the ```My certificates``` list to explain that it contains certificates that have been issued to
+  avoid confusion as to why certificates may not be appearing.
+
+### Changed
+- The course full name is now used in emails.
+
+### Fixed
+- Added missing string used in course reset.
+
+## [3.1.16] - 2017-09-04
+### Added
+- New digital signature element (uses existing functionality in the TCPDF library).
+- Ability to duplicate site templates via the manage templates page.
+- Ability to delete issued certificates for individual users on the course report page.
+
+### Changed
+- Removed usage of magic getter and abuse of ```$this->element```. The variable ```$this->element``` will still be
+  accessible by any third-party element plugins, though this is discouraged and the appropriate ```get_xxx()```
+  method should be used instead. Using ```$this->element``` in ```definition_after_data()``` will no longer work.
+  Please explicitly set the value of any custom fields you have in the form.
+
+### Fixed
+- Added missing ```confirm_sesskey()``` checks.
+- Minor bug fixes.
+
+## [3.1.15] - 2017-08-11
+### Added
+- Added much needed Behat test coverage.
+
+### Changed
+- Minor language string changes.
+- Made changes to the UI when editing a certificate.
+  - Moved the 'Add element' submit button below the list of elements.
+  - Added icon next to the 'Delete page' link.
+  - Changed the 'Add page' button to a link, added an icon and moved it's location to the right.
+  - Do not make all submit buttons primary. MDL-59740 needs to be applied to your Moodle install in order to notice the change.
+
+### Fixed
+- Issue where the date an activity was graded was not displaying at all.
+
+## [3.1.14] - 2017-08-05
+### Changed
+- Renamed the column 'size' in the table 'customcert_elements' to 'fontsize' due to 'size' being a reserved word in Oracle.

-QUICK INSTALL
-=============
+# The custom certificate activity
 
-There are two installation methods that are available. Follow one of these, then log into your Moodle site as an administrator and visit the notifications page to complete the install.
+This activity allows the dynamic generation of PDF certificates with complete customisation via the web browser.
 
-==================== MOST RECOMMENDED METHOD - Git ====================
+## Installation
 
-If you do not have git installed, please see the below link. Please note, it is not necessary to set up the SSH Keys. This is only needed if you are going to create a repository of your own on github.com.
+There are two installation methods that are available. 
 
-Information on installing git - http://help.github.com/set-up-git-redirect/
+Follow one of these, then log into your Moodle site as an administrator and visit the notifications page to complete the install.
 
-Once you have git installed, simply visit the Moodle mod directory and clone git://github.com/markn86/moodle-mod_customcert.git, remember to rename the folder to customcert if you do not specify this in the clone command
+### Git
 
-Eg. Linux command line would be as follow -
+This requires Git being installed. If you do not have Git installed, please visit the [Git website](https://git-scm.com/downloads "Git website").
 
-git clone git://github.com/markn86/moodle-mod_customcert.git customcert
+Once you have Git installed, simply visit your Moodle mod directory and clone the repository using the following command.
 
-Use git pull to update this repository periodically to ensure you have the latest version.
+```
+git clone https://github.com/markn86/moodle-mod_customcert.git customcert
+```
 
-==================== Download the customcert module. ====================
+Then checkout the branch corresponding to the version of Moodle you are using with the following command. Make sure to replace MOODLE_32_STABLE with the version of Moodle you are using.
 
-Visit https://github.com/markn86/moodle-mod_customcert and download the zip, uncompress this zip and extract the folder. The folder will have a name similar to markn86-moodle-mod_customcert-c9fbadb, you MUST rename this to customcert. Place this folder in your mod folder in your Moodle directory.
+```
+git checkout MOODLE_32_STABLE
+```
 
-nb. The reason this is not the recommended method is due to the fact you have to over-write the contents of this folder to apply any future updates to the customcert module. In the above method there is a simple command to update the files.
+Use `git pull` to update this repository periodically to ensure you have the most recent updates.
 
+### Download the zip
 
-Customisation
-=============
+Visit the [Moodle plugins website](https://moodle.org/plugins/mod_customcert "Moodle plugins website") and download the zip corresponding to the version of Moodle you are using. Extract the zip and place the 'customcert' folder in the mod folder in your Moodle directory.
 
-========================= Add Fonts to TCPDF. =========================
+## More information
 
-For customization, you have a couple of options in the Custom Certificate module. One of the most common customizations is, adding fonts to the Certificate creator.
+Visit the [wiki page](https://docs.moodle.org/en/Custom_certificate_module "Wiki page") for more details. Also, it is a wiki, so please feel free to edit it. :)
 
-Custom Certificate uses a pdf creator called TCPDF, which embeds fonts into the PDF file, so that you can view fonts, even though they are not installed on the target machine. This requires you to tell TCPDF which fonts to take.
+## License
 
-Importing Fonts into TCPDF is quite simple:
-
-1. Convert the font you want embedded into the tcpdf format (for example using [http://fonts.snm-portal.com][1] or [http://www.xml-convert.com/en/convert-tff-font-to-afm-pfa-fpdf-tcpdf][2])
-
-2. Put the converted files into the folder: `/path/to/moodle/lib/tcpdf/fonts`
-
-3. Use the font in your certificate builder
-
-4. Enjoy
-
-> Please note that inserting a file into the tcpdf folder is considered a "core hack" and might not be available on some commercially hosted systems. Please check your providers agreement on the topic to make sure this is something you're allowed to do.
