+
+### Core CiviCRM
+
+- **[CRM-21753](https://issues.civicrm.org/jira/browse/CRM-21753) Support
+ 'criteria' in url on batch merge form
+ ([11658](https://github.com/civicrm/civicrm-core/pull/11658))**
+
+ A new `criteria` URL parameter for finding duplicate contacts allows you to
+ specify API criteria to only search for duplicates among a subset of contacts.
+
+- **Add New API Call To Get All Unique Fields For Given Entity
+ ([11990](https://github.com/civicrm/civicrm-core/pull/11990))**
+
+ This adds a new `getunique` API method that will go through the indexes of an
+ entity table and return all unique fields (including combination indexes).
+
+- **[CRM-21849](https://issues.civicrm.org/jira/browse/CRM-21849) Add Link To
+ Edit Relationship Types
+ ([11853](https://github.com/civicrm/civicrm-core/pull/11853))**
+
+ This change adds a settings button next to the Relationship Type field on the
+ Edit Relationship screen which allows you to edit relationship types.
+
+- **[dev/core#90](https://lab.civicrm.org/dev/core/issues/90) Apply disabling
+ Full Group By to reports
+ ([12047](https://github.com/civicrm/civicrm-core/pull/12047),
+ [12043](https://github.com/civicrm/civicrm-core/pull/12043))**
+
+ This applies the disabling of ONLY_FULL_GROUP_BY sql mode to reports and on
+ specific queries as needed to enable tests to run on MySQL 5.7
+
+- **[dev/core#66](https://lab.civicrm.org/dev/core/issues/66) Standardise
+ Address code in Contact summary report & enable links
+ ([11993](https://github.com/civicrm/civicrm-core/pull/11993))**
+
+ This change refactors the Address related code as part of a drive to get
+ addresses for multiple contacts in one report. This change adds prefixing
+ into the function used to add the columns, an approach taken from the Extended
+ Reports extension.
+
+- **[dev/translation#9](https://lab.civicrm.org/dev/translation/issues/9) Create
+ API Action to rebuild Multilingual Schema
+ ([11967](https://github.com/civicrm/civicrm-core/pull/11967))**
+
+ This change adds an API method called `System.rebuildmultilingualschema` to
+ allow users to rebuild the multilingual schema.
+
+- **Add 'addToDeveloperTab' in more places to expose sql in use (permission
+ limited) ([11947](https://github.com/civicrm/civicrm-core/pull/11947))**
+
+ The Database Log report includes a number of database queries besides the main
+ query. These populate temporary tables, among other things. The SQL for
+ these ancillary queries is now visible in the Developer tab alongside the main
+ query.
+
+- **Fix API template ([11970](https://github.com/civicrm/civicrm-core/pull/11970))**
+
+ This PR fixes structure and style of CiviCRM API explorer to make it look like
+ other pages to give unified interface between screens.
+
+### CiviContribute
+
+- **[dev/core#73](https://lab.civicrm.org/dev/core/issues/73) - Add invoice
+ number to bookkeeping report
+ ([12020](https://github.com/civicrm/civicrm-core/pull/12020))**
+
+ Invoice Number and Invoice Reference are now both available in the bookkeeping
+ transactions report. Before this change, only Invoice ID was shown as a column
+ in bookkeeping report.
+
+### CiviEvent
+
+- **[CRM-20879](https://issues.civicrm.org/jira/browse/CRM-20879) Extend
+ self-service event registration transfer to backend
+ ([10695](https://github.com/civicrm/civicrm-core/pull/10695))**
+
+ This change adds links to "Transfer or Cancel" an event registration when
+ viewing an event registration for a participant and when viewing a contact's
+ event registrations from the event tab on the contact's record.
+
+### CiviMail
+
+- **[dev/core#53](https://lab.civicrm.org/dev/core/issues/53) Add in stats to AB
+ tests and add in clickthrough and opened % stats to mailing reports
+ ([11957](https://github.com/civicrm/civicrm-core/pull/11957))**
+
+ This change adds Mailing delivery stat percentages to AB tests and also adds
+ in new opened and clickthrough rate stats.
+

+
+### Core CiviCRM
+
+- **[dev/core#98](https://lab.civicrm.org/dev/core/issues/98) Searching by any
+ Address fields with location type other than primary throw DB error
+ ([12081](https://github.com/civicrm/civicrm-core/pull/12081))**
+
+ This change resolves a database error that would appear in Search Builder when
+ a user picks an address field with a location type other than "Primary".
+
+- **[dev/core#91](https://lab.civicrm.org/dev/core/issues/91) Search Builder
+ Improvements ([12058](https://github.com/civicrm/civicrm-core/pull/12058))**
+
+ On the Search Builder screen, this change limits the MySQL operators
+ available based on the type of field (string, date etc.).
+
+- **[dev/core#75](https://lab.civicrm.org/dev/core/issues/75) - warning message
+ after an activity is created
+ ([12027](https://github.com/civicrm/civicrm-core/pull/12027))**
+
+- **Translate strings in "Report" UI, et al
+ ([12009](https://github.com/civicrm/civicrm-core/pull/12009) and
+ [11988](https://github.com/civicrm/civicrm-core/pull/11988))**
+
+ A number of phrases, particularly in reports and CiviGrant, were not wrapped
+ in a translation function.
+
+- **Improve input handling in get-cases AJAX API
+ ([12017](https://github.com/civicrm/civicrm-core/pull/12017))**
+
+ Changes case type id and status id to be 'CommaSeparatedIntegers' instead of
+ 'String' to improve input handling in get-cases AJAX API.
+
+- **[CRM-19885](https://issues.civicrm.org/jira/browse/CRM-19885) Scheduled
+ Reminders: lack of default form values leads to SQL syntax error
+ ([11972](https://github.com/civicrm/civicrm-core/pull/11972))**
+
+ This fixes a regression from CRM-19853 where some fields were changed to text
+ input without defining default values. Specifically, the problem involved
+ integer fields start_action_offset, repetition_frequency_interval,
+ end_frequency_interval, which aren't required fields. Leaving these blank led
+ to `NULL` values in the database, which then led to SQL syntax errors.
+
+- **[dev/core#64](https://lab.civicrm.org/dev/core/issues/64) - In custom
+ searches, column headings are being ignored
+ ([12001](https://github.com/civicrm/civicrm-core/pull/12001))**
+
+ This change fixes a regression where for custom searches--ones that come
+ installed with core CiviCRM as well as user-defined ones--the column headings
+ defined in the custom search code were being ignored. This issue began in
+ CiviCRM 5.0.0.
+
+- **[dev/core#70](https://lab.civicrm.org/dev/core/issues/70) On any custom
+ search 'Print selected rows' action doesn't retain columns/values
+ ([12010](https://github.com/civicrm/civicrm-core/pull/12010))**
+
+- **[dev/core#48](https://lab.civicrm.org/dev/core/issues/48) Fix PDF Letter
+ only generates a single letter when multiple contact IDs are specified
+ ([11985](https://github.com/civicrm/civicrm-core/pull/11985))**
+
+ This change fixes a bug where when multiple contact IDs are specified via
+ print/merge task the PDFLetterCommon code overwrote them with a single contact
+ ID of the logged in user. This means that only a single PDF letter is
+ printed/generated. This PR only uses the logged in contact ID if no contact
+ IDs have been specified.
+
+- **[dev/core#59](https://lab.civicrm.org/dev/core/issues/59) scheduled reminder
+ email validation
+ ([11973](https://github.com/civicrm/civicrm-core/pull/11973))**
+
+ This change makes it so that the email address field on the scheduled reminder
+ form is validated. Before this change, a non-email value could be stored in
+ the field which would result in a silent failure.
+
+- **[CRM-20598](https://issues.civicrm.org/jira/browse/CRM-20598) Phone ext in
+ profile edit messing with address
+ ([11978](https://github.com/civicrm/civicrm-core/pull/11978))**
+
+ This change fixes a bug where when using a profile in edit mode with "Phone
+ and Extension" on primary field and some primary address fields (street, city,
+ country): it works fine the first time the profile is used, but it removes the
+ existing address when a user tries to use the profile a second time.
+
+- **AllCoreTables - Generate file every time
+ ([11755](https://github.com/civicrm/civicrm-core/pull/11755))**
+
+ The auto-generated file AllCoreTables was not being updated as often as
+ necessary, and the freshness checks were almost as expensive as just generating
+ the file, if not more, this was causing issues for the Attachment API. This
+ change makes it so the file is generated every time.
+
+- **Prevent hard-fail when section header / group by option chosen on logging
+ report ([11953](https://github.com/civicrm/civicrm-core/pull/11953))**
+
+- **[CRM-21855](https://issues.civicrm.org/jira/browse/CRM-21855) Editing "A"
+ side of relationship copies values to "B" side
+ ([11965](https://github.com/civicrm/civicrm-core/pull/11965))**
+
+ When editing a relationship type, values in the "Relationship A to B" column
+ were copied to the "Relationship B to A" column.
+
+- **[CRM-21523](https://issues.civicrm.org/jira/browse/CRM-21523) scheduled
+ reminders: when using repetition, require frequency intervals
+ ([11377](https://github.com/civicrm/civicrm-core/pull/11377))**
+
+- **Move help section outside the container
+ ([12031](https://github.com/civicrm/civicrm-core/pull/12031))**
+
+ This moves the help section markup on the Find and Merge Duplicate Contacts
+ page to preserve consistency among other screens.
+
+### CiviCase
+
+- **[CRM-21843](https://issues.civicrm.org/jira/browse/CRM-21843) Case
+ activities delimiter not working
+ ([11961](https://github.com/civicrm/civicrm-core/pull/11961))**
+
+ This change fixes a bug in exporting cases where the last column would contain
+ all the activity fields jammed together.
+
+- **Fix select2 value updation for crmAddName Directive
+ ([11979](https://github.com/civicrm/civicrm-core/pull/11979))**
+
+ This fixes a bug where the Case Type options selection field was not
+ populating properly.
+
+- **[dev/core#54](https://lab.civicrm.org/dev/core/issues/54) - Activity created
+ for case role relationship is not assigned to correct contact
+ ([11960](https://github.com/civicrm/civicrm-core/pull/11960))**
+
+ This change fixes a bug where if the user added a role for a case. The activity
+ created was assigned to the client instead of the relationship contact.
+
+- **[dev/core#137](https://lab.civicrm.org/dev/core/issues/137) Fix Find Deleted
+ Cases ([12219](https://github.com/civicrm/civicrm-core/pull/12219))**

+ error.

+
+ This change makes it so the contribution detail report works in both full
+ group by and non full group by mode.
+
+- **[dev/core#78](https://lab.civicrm.org/dev/core/issues/78) - Incorrect
+ Payment Processor for Recurring Payments
+ ([12030](https://github.com/civicrm/civicrm-core/pull/12030))**
+
+ The Authorize.net instant payment notification (IPN) code did not properly
+ accommodate multiple Authorize.net payment processor instances and would
+ sometimes load the incorrect processor.
+
+- **[dev/core#72](https://lab.civicrm.org/dev/core/issues/72) fix payflow bug
+ for amount ([12019](https://github.com/civicrm/civicrm-core/pull/12019))**
+
+ Fixes a bug where PayflowPro throws an error due to more than 4 decimal places
+ in the amount.
+
+- **[CRM-19752](https://issues.civicrm.org/jira/browse/CRM-19752) Slow query
+ created by financial type acls
+ ([11657](https://github.com/civicrm/civicrm-core/pull/11657))**
+
+ This change is to improve financial ACL code that was unnecessarily slowing
+ down the contact dashboard on sites where financial ACLs are not enabled.
+ Financial ACL joins and conditions are no longer added where financial ACLs
+ are not enabled.
+
+- **[dev/financial#11](https://lab.civicrm.org/dev/financial/issues/11) email
+ invoice fails with validation error
+ ([11971](https://github.com/civicrm/civicrm-core/pull/11971))**
+
+ The "Email Invoice" action would result in an outgoing error message: The mail
+ library returned the following error message: Validation failed for: ""NAME"".
+
+- **Fix template for widget
+ ([11902](https://github.com/civicrm/civicrm-core/pull/11902))**

+ aligned properly under it.
+
+- **Remove usage of deprecated paymentProcessorType function
+ ([12039](https://github.com/civicrm/civicrm-core/pull/12039))**

+
+### CiviEvent
+
+- **Fix Soft credit personal note ton limit to 255 characters (DB limit).
+ ([12056](https://github.com/civicrm/civicrm-core/pull/12056))**
+
+ This change fixes a bug where when a user is donating on a CiviEvent Personal
+ Campaign page, checks the "Show my support in public honor roll", and puts a
+ message in the "Personal Note" box that is longer than 255 characters.
+ Submitting the donation would succeed, but the page threw a fatal error before
+ the receipt is sent.
+
+- **[dev/core#60](https://lab.civicrm.org/dev/core/issues/60) Fix for check
+ number no longer exposed dev/core/issues/60
+ ([12059](https://github.com/civicrm/civicrm-core/pull/12059))**

+ ([119](https://github.com/civicrm/civicrm-wordpress/pull/119))**
