## Features
### Core CiviCRM

[15820](https://github.com/civicrm/civicrm-core/pull/15820),
[15825](https://github.com/civicrm/civicrm-core/pull/15825)
and [15876](https://github.com/civicrm/civicrm-core/pull/15876))**
Begins work to enforce a common naming convention for temporary tables.
- **Performance issue when exporting to CSV from reports with custom fields
([dev/report#19](https://lab.civicrm.org/dev/report/issues/19):
[15248](https://github.com/civicrm/civicrm-core/pull/15248))**
Performance improvements when exporting a report to CSV.
- **Memory error on creating large pdfs
([dev/core#574](https://lab.civicrm.org/dev/core/issues/574):
[13232](https://github.com/civicrm/civicrm-core/pull/13232))**
Improves performance when creating PDFs.
- **Update Country list: change Macedonia, Republic of into North Macedonia
([dev/core#1166](https://lab.civicrm.org/dev/core/issues/1166):
[15997](https://github.com/civicrm/civicrm-core/pull/15997))**
Updates the name of "Macedonia, Republic of" to "North Macedonia" in
accordance with the iso 3166-1 list.
- **Default to 'copy' for non-empty fields on merge screen
([dev/core#1339](https://lab.civicrm.org/dev/core/issues/1339):
[15595](https://github.com/civicrm/civicrm-core/pull/15595))**
Updates the Merge screen to default to copy for all non empty fields. This
change makes it easier to keep too much data but harder to lose some.
- **Tagsets should display vertically in activity/new case forms
([dev/core#1346](https://lab.civicrm.org/dev/core/issues/1346):
[15649](https://github.com/civicrm/civicrm-core/pull/15649))**
Improves the User interface of the "New Activity" and "New Case" forms by
displaying the tag fields vertically instead of horizontally.
- **Make utf8mb4 status check language more for the general consumer
([15946](https://github.com/civicrm/civicrm-core/pull/15946))**
This alters the language on the utf8mb4 status check so that it is a bit more
general in nature and hopefully easier to digest for end users.
- **Include Metadata on advanced search form for membership, grant, pledge,
fields ([15936](https://github.com/civicrm/civicrm-core/pull/15936))**
Adds the ability filter on fields like `membership_join_date` and
`pledge_payment_start_date` on the advanced search form via url parameters.
- **Replace all instances of CRM_Core_Fatal with throw new CRM_Core_Exception
(Work towards [dev/core#560](https://lab.civicrm.org/dev/core/issues/560):
[15903](https://github.com/civicrm/civicrm-core/pull/15903),
[15770](https://github.com/civicrm/civicrm-core/pull/15770),
[15941](https://github.com/civicrm/civicrm-core/pull/15941),
[15775](https://github.com/civicrm/civicrm-core/pull/15775) and
[15822](https://github.com/civicrm/civicrm-core/pull/15822))**
Work towards throwing exceptions instead of fatal errors.

([15847](https://github.com/civicrm/civicrm-core/pull/15847))**
Makes the CiviCRM Menu opaque to improve readability.
- **Improve datePicker placeholder/icons
([15848](https://github.com/civicrm/civicrm-core/pull/15848))**
Small tweaks to the datepicker widget to improve flexibility & consistency.
- **modified shared address note under contact dashboard
([15666](https://github.com/civicrm/civicrm-core/pull/15666) and
[15769](https://github.com/civicrm/civicrm-core/pull/15769))**
Improves the note below the Shared Address field to include a link to the
contact that the address lives on to make it easier for get to the shared
address to edit it.
- **Grant in Edit mode doesn't show the associated contact and standardize all
screens accordingly. (Work Towards
[dev/core#1065](https://lab.civicrm.org/dev/core/issues/1065):
[15757](https://github.com/civicrm/civicrm-core/pull/15757),
[15833](https://github.com/civicrm/civicrm-core/pull/15833) and
[15840](https://github.com/civicrm/civicrm-core/pull/15840))**
Work towards ensuring that a clickable link to the associated contact is
included on the Grant Form in edit mode and the Membership Renewal Form and
standardizes the display of associated contacts across edit forms.
### CiviCase
- **Enable Case search metadata on Advanced Search Form
([15928](https://github.com/civicrm/civicrm-core/pull/15928))**
This change makes it so one can pass case search parameters using url
parameters on the Advanced Search Form.
### CiviContribute
- **Develop getter & setter structure for Payment classes (Work Towards
[dev/financial#82](https://lab.civicrm.org/dev/financial/issues/82):
[15697](https://github.com/civicrm/civicrm-core/pull/15697))**
This PR adds a new class, `Civi\Payment\PropertyBag` which will eventually
replace the wild `$params` array that gets thrown at payment processors, with
a standardized, at least minimally validated and type cast object. It uses the
new class in one very minimal way and adds some comments to outline future
work. This is a non functional change that lays the groundwork for future
work.
- **Always display amount paid even if it is 0.00. Blank looks like it's missing
data rather than nothing paid
([16021](https://github.com/civicrm/civicrm-core/pull/16021))**
This improves user experience by displaying contributions of 0 as 0 instead
of blank.
- **Contribution url params - add contribution_page_id as a supported url
parameter ([15785](https://github.com/civicrm/civicrm-core/pull/15785))**
Adds `contribution_page_id` as a supported url parameter on the advanced
search form.
### CiviMail
- **CiviMail - Only display "Headers and Footers" if there are headers and
footers ([15326](https://github.com/civicrm/civicrm-core/pull/15326))**
Makes it so when creating a CiviMail Mailing the "Headers and Footers" tab
only displays if there are Headers and/or Footers configured on the site.
### Drupal Integration
- **Add participant is_test field to views
([590](https://github.com/civicrm/civicrm-drupal/pull/590))**
Makes the Participant `is_test` field available in views.
### PayPal Implementation
- **PayPalImpl: Add SOLUTIONTYPE parameter that triggers allowing to pay without
having to create a paypal account.
([15523](https://github.com/civicrm/civicrm-core/pull/15523))**
Adds a `SOLUTIONTYPE` parameter to the PayPal checkout values so that one can
make a contribution without having to create an account.
## Bugs resolved
### Core CiviCRM

([dev/core#523](https://lab.civicrm.org/dev/core/issues/523):

Fixes the LYBUNT charts.
- **Search builder error on Membership source field.
([dev/core#1390](https://lab.civicrm.org/dev/core/issues/1390):
[15845](https://github.com/civicrm/civicrm-core/pull/15845))**
Fixes an error: "DB error: syntax error" when adding "Membership Source" on
the search builder screen.
- **Option to open navigation item in new window (if present)
([dev/core#1398](https://lab.civicrm.org/dev/core/issues/1398):
[15861](https://github.com/civicrm/civicrm-core/pull/15861))**
Ensures the target attribute is respected for CiviCRM Navigation menu submenu
items.
- **CIVI-SA-2019-21 may lead to regressions when following typehints on
CRM_Core_BAO_Setting::setItem() (Work Towards
[dev/core#1425](https://lab.civicrm.org/dev/core/issues/1425):
[15981](https://github.com/civicrm/civicrm-core/pull/15981),
[15988](https://github.com/civicrm/civicrm-core/pull/15988) and
[15980](https://github.com/civicrm/civicrm-core/pull/15980))**

- **allow PCP report to filter on contribution status
([16024](https://github.com/civicrm/civicrm-core/pull/16024))**
The PCP report template lists all PCP pages with total number of contributions
made against each PCP page and total amount raised. Before this change the
report had no filter for Contribution Status so Cancelled Contributions were
showing and throwing off the totals. With this change there is a filter for
contribution status allowing users to filter this list as they see fit for
their use case.
- **Only add in the metadata for advanced search if user has access to the
relevant component
